Summary

This report, commissioned by the National Highway Traffic Safety Administration (NHTSA) and conducted by the Volpe National Transportation Systems Center, addresses the safety challenges associated with the development of Plastics and Composites Intensive Vehicles (PCIVs). The study was motivated by Congressional guidance and national sustainability goals, specifically the need to improve fuel efficiency and reduce greenhouse gas emissions through vehicle light-weighting. As automakers increasingly substitute steel with plastics, composites, and other advanced materials to meet Corporate Average Fuel Economy (CAFE) standards, there is a critical need to ensure these lighter vehicles maintain or exceed current crash safety performance. The report specifically prioritizes the safety of older drivers, whose vulnerability in crashes is increasing due to demographic shifts. The methodology involved a comprehensive situation analysis to assess the state of knowledge regarding automotive light-weighting and crash safety. This included a review of technical literature, national and international research efforts, and existing standards from organizations such as SAE and ASTM. The study also incorporated focused interviews with subject matter experts from federal agencies, industry, academia, and standards bodies to identify knowledge gaps, barriers to deployment, and research priorities. The analysis synthesized inputs from previous workshops, including those sponsored by the American Plastics Council, and aligned findings with the Department of Energy’s FreedomCAR initiatives and NHTSA’s integrated safety strategy. The findings identified significant opportunities and challenges in using advanced materials for structural and safety applications. Key knowledge gaps were found in predicting the crash performance of plastics and composites, particularly regarding energy absorption and compatibility with heavier vehicles. The report outlines specific research needs, including the development of predictive engineering tools and testing standards for composite materials. It highlights that while light-weighting offers substantial fuel economy improvements—estimated at 5–7 percent for every 10 percent weight reduction—it requires compensatory safety enhancements to address vehicle-to-vehicle compatibility issues. The study also noted that current plastics usage averages 150 kg per vehicle, with projections for substantial increases over the next two decades. The significance of this work lies in the development of a PCIV Safety Roadmap targeting deployment by 2020. This roadmap synthesizes near-term (1–3 years), mid-term (3–5 years), and long-term (up to 2020) research and development priorities. It aims to facilitate the design, verification, and integration of safe, fuel-efficient PCIVs that comply with Federal Motor Vehicle Safety Standards. By establishing clear milestones and performance metrics, the report provides a strategic framework for public-private partnerships to overcome technical barriers, ensuring that the transition to lighter vehicles does not compromise occupant protection, particularly for aging populations.

Key finding

The study developed a comprehensive PCIV Safety Research Roadmap identifying specific near-term, mid-term, and long-term R&D priorities to ensure crash safety compliance for lightweight vehicles by 2020.
