Composites For Sustainability
Wednesday January 25, 2023 1:30 pm - 2:30 pm

Don’t look up: How Increasing demand for sustainability will impact the future for Composite Material suppliers.

Read more

Positively or negatively, the increasing demand for more circular, sustainable products will directly impact the future for composite material suppliers. Their success will depend on how well they understand their influence on both sustainability and circularity, their acceptance of change, and the steps they take to today to position themselves for tomorrow. As consumer demand increases for more circular and sustainable products, designers and engineers must now look at the entire life cycle of the product along with its individual parts and materials to consider the overall sustainability and circularity. Fundamentally it begins and ends with material suppliers, but how well do composite material suppliers understand the difference between sustainability and circularity? Aren’t they the same? Can you increase sustainability but lower circularity? Sort of, and yes. We will discuss examples of Wind Blades and Tesla Tires, and through Life Cycle Analysis (LCA) evaluate how both provided greater sustainability during their operation but holistically aren’t truly sustainable or circular products. The potentially billion-dollar question, is the composite industry ready for change? The first signs of increasing demand for sustainable materials are occurring in the automotive, packaging, and building industries; some of the largest consumers of materials. Consider Porsche and Daimler who have both launched initiatives with goals of seeking carbon neutral supply chains in the next 7-10. Designers and Engineers must now consider these factors. How will companies respond? We will highlight how one global material supplier is preparing themselves for this imminent change by incorporating LCA concurrently with their strategic planning to alter their strategic direction, redefine their product strategy, and differentiate themselves. As demand increases companies will have two choices, they “don’t look up” and continue forward as normal or they “look up” and acknowledge the large asteroid of change that is entering their world. Increasing demand for more sustainable and circular materials will inevitably spur the next wave of material innovation and once again shift the market landscape creating new technologies, new entrants and exits for some existing players. For the companies that choose to “look up”, they must prepare now by assessing the changing needs of the market, identifying new threats and opportunities, and defining strategies that better position them for future growth. For those companies that choose not to “Look Up”, then their very existence may be in jeopardy.

Automotive Structural Component Design Analysis & Manufacturing
Thursday January 26, 2023 8:00 am - 9:00 am

Design and development of an ultra-lightweight carbon fiber reinforced thermoplastics composites automotive closure system.

Recent global energy markets and supply chain disruptions have reiterated the necessity to improve the efficiency of transportation systems. In the U.S., one of the biggest automotive and energy markets, transportation accounted for more than a 1/4th of all energy consumption and resulted in nearly 1/3rd of all CO2 emissions. Although many approaches have been investigated to improve the fuel efficiency of vehicles, light-weighting has proven to be particularly effective as it allows automotive original equipment manufacturers (OEMs) to improve fuel efficiency, incorporate value-adding features without a weight penalty, and extract better performance. Historically, there have been several successful attempts focused on body-in-white (BiW) light-weighting as it accounts for more than 35% of the total vehicle weight. However, closure systems, which account for almost 50% of the total structural mass of the vehicle, are often overlooked. This is because closure systems need to meet a diverse range of design requirements such as crashworthiness during side impacts, stiffness, strength, corrosion resistance, durability, fit and finish, NVH and weather sealing. Since many of these design requirements are same as those of the larger BiW, light-weighting approaches using fiber reinforced (FRP) composites developed for closures can be translated to light-weighting other structural system of the vehicle as well. Thus, the U.S. Department of Energy’s (DOE) Vehicle Technologies Office has initiated a multi-year research and development program to enable cost-effective light-weighting of the closure system, in this case the driver side door, of a commercial SUV. The designs developed as part of this initiative would enable weight reduction of 42.5% compared to the baseline steel door system, with a maximum allowable cost increase of $5 for every pound of weight reduced. Furthermore, the conceived designs were to be compatible with large-scale composite manufacturing processes to enable production of at least 20,000 vehicles annually. With the growing focus on use of sustainable materials and enabling recyclability, the designs were to enable 100% recyclability for the structural components. This addresses the increasingly stringent regulations such as the 95% recyclability required as per European standards. To address these objectives a wholistic systems design and optimization approach was adopted to ensure development of feasible carbon fiber reinforced plastic (CFRP) composite designs. In addition to superior specific mechanical properties, composites also enable significant parts consolidation. Thus, many smaller stamped components and reinforcing brackets were consolidated into two distinct high-performance carbon fiber reinforced thermoplastic (CFR-TP) composite parts suitable for fast and scaled production using thermoforming. The systems approach followed in design conceptualization, allowed for nearly 40% parts consolidation, which in turn reduced the tooling and assembly costs significantly. The systems approach employed, the design studies conducted and resulting assessment and down-selection of feasible designs are being presented in subsequent sections.

Finite element analysis and performance evaluation of an ultra-lightweight continuous carbon fiber thermoplastics composite door assembly.

An effective approach widely adopted by the transport industry to create fuel-efficient and sustainable solutions is light weighting. Among the various systems considered for light weighting in the automotive industry, closure systems have received least attention although their contribution to the overall structural mass is about 50%. Part of reason being the stringent crashworthiness requirements that demand high ductility and energy absorption. In addition, a diverse range of requirements including crash safety, durability, strength, fit, finish and NVH make the light-weighting of closure systems an extremely challenging task. To this end, the Clemson Composites Center embarked on an arduous task of light weighting an OEM’s vehicle door assembly by 42.5% while meeting all functional requirements at a moderate cost increment of less than $5 for every pound of weight saved. Several door designs were investigated using an integrated design, finite element analysis and optimization approach. The designs were evaluated using static load cases carefully derived from daily use and misuse of the baseline door. More importantly, finite element analysis was employed to assess the crashworthiness of the door assembly through three non-linear load cases: (a) quasi-static pole test (FM VSS 214S), (b) full pole test (FM VSS 214) and (c) moving deformable barrier test (IIHS SI MDB). As an essential step, the material card properties and parameters were optimized and validated at a sub-component level. The crashworthiness of the door designs was examined based on a set of key performance indicators recommended by the OEM. This presentation provides detailed assessment of the door designs thoroughly investigated for static and crash load cases and shows feasible door design that is ultra-light weight while meeting all performance requirements. Key attributes include, design optimization, subcomponent-level study, static and crash analyses of the door designs. Lastly, this work sheds light on the process involved in designing the thermoplastics composite door for crash performance based on inputs from a Manufacturing-to response pathway to validate and optimize the door’s crash response to that of a metal baseline.

Digital lifecycle: a radical redesign of automotive product development for continuous fiber thermoplastics composite

The development and adoptions of new and innovative materials has seen a major uptick due to several factors from light weighting to sustainability. However, a major roadblock to the adoption of these materials is the conventional automotive product development process that is rooted in costs, risk mitigation, catastrophic failure, and the lack of expertise at the systems and design level. New materials like carbon fiber reinforced thermoplastic composites offer high stiffness, strength, lightweight, recyclability while having short cycle times however, their adoption is severely limited by complex material architecture (localized stiffness properties), inability to predict manufacturing defects and model composite failure behavior. Repurposing this development process by architecting a simulation intensive paradigm that incorporates nuanced materials and manufacturing inputs on design, static, dynamic and NVH response could provide decision makers with the feedback necessary to facilitate this change. Clemson Composites Center (CCC) has embarked on a new platform that can revolutionize product lifecycle through a novel Manufacturing-to-Response (MTR) pathway. The MTR pathway seeks to address these limitations by establishing an end-to-end virtual chain that tries to accurately capture and simulate material properties, design, and process effects that can be structurally mapped for CAE predictions. This formed the centerpiece of a Department of energy (DOE) project whose goal is to design and develop a door which is 42.5% lighter than the baseline door while meeting all functional requirements at a moderate cost increment of less than $5 for every pound of weight saved. In this regard thermoforming process of continuous carbon fiber reinforced thermoplastic composites (CFRTP) offer significant advantage in terms of ductile behavior and for large scale production, such as reduced cycle times. This presentation delves into the details of this MTR pathway that derives properties at the coupon level but goes on to be validated at a subcomponent and component level. Key attributes include, capturing of residual stresses during rapid cooling from the elevated temperatures, which are predicted by implementation of classical laminate theory (CLT) and its mapping for structural performance evaluation. Lastly, this work sheds light on the numerical investigation conducted to optimize the crash performance of the thermoplastic composite door using the manufacturing process inputs to meet targets through implementation of the MTR pathway.

Novel Methods for Composites Recycling via Pyrolysis

Read more

Composites are unique materials in many respects. When fabric woven from carbon fibers is joined with a thermoset resin in a controlled environment, it results in a very strong material, especially evaluated on a pound-for-pound basis against metals and ceramics. One aspect of this construction that provides great strength lies in the fiber-matrix adhesion which facilitates load transfer to the reinforcement of the composite. This fiber-matrix adhesion is promoted by the polarity of the usual thermoset matrices, and properly designed sizing materials coating the fibers. It’s a two-edged sword, though. Although the resin and the fibers are quite strong together, they are very difficult to pull apart once they’re formed, in order to recover the materials and use them again in the future. The crosslinked nature of thermoset matrices dictates combustion as the most viable option for separation of the constituents. As such, composite structures formed with industry-standard thermoset resins have a single-use lifespan. The least expensive end-use option is simply landfill disposal. However, by isolating the dry fibers by burning off the resin (a process called pyrolysis), the fibers are able to be reclaimed and processed again in useful ways. This study focuses on pyrolysis and ways to optimize its process for use of reclaimed carbon fiber. The aim is to showcase its environmentally-friendly capabilities through making new composite structures with fibers reclaimed via pyrolysis to lessen landfill waste.

Forwarding Looking at Wind Turbine Blade Recycling in the United States

Read more

Over recent years, wind turbine blade (WTB) waste management has become a focus and priority of not only the wind industry, but the composites industry as a whole. Due to the polymeric structure, size, and volume of WTBs, decommissioning and recycling at end of service is challenging from a business and engineering perspective. While some WTB recycling occurs in the United States, current infrastructure and businesses are not poised to handle the current number of decommissioned blades and the projected number of blades that will be decommissioned in the coming years. Even with the existing challenges of recycling WTBs, paths forward exist but require further analysis to identify which to innovate and develop further. Here, we will examine opportunities to further WTB recycling beginning from manufacturing and ending with decommissioning and end of service management. The potential pathways for recycling will be identified along with some of the potential advantages and disadvantages associated with each. Furthermore, forecasting of how WTB manufacturing, material selection, and design will affect these recycling pathways will also be discussed. While developments to handle WTB recycling appear to be forthcoming in the United States, robust, economical, and innovated solutions will be required to best utilized WTBs at end of service.

Sustainability in Carbon Fiber Reinforced Thermosets

Read more

Decarbonization has been a focus of the world in the past few decades, however, with multiple global headwinds, the progress toward it was already slower than necessary. Carbon fiber reinforced thermosets are advantageous in many applications over incumbent materials and see increasing demand but raise serious environmental and energy concerns when it comes to scrap and waste management. Therefore, how to effectively reclaim carbon fibers and matrix polymer for reuse is critical to retain the embodied energy during manufacturing and the carbon for longer life. The state-of-the-art recycling methods and their shortcomings will be discussed. PNNL’s collaborative efforts with academia and industry in this field will be shared along with our current strategies, challenges, and visions.
