Historically, studies by the National Highway Traffic Safety Administration (NHTSA) in support of CAF� rulemaking indicate that lightweighting vehicles lead to degraded safety. However, recent studies provided to NHTSA show that good designs for lightweighting can provide equivalent safety. This presentation highlights two studies funded by NHTSA in part to address these latest findings. The first is a George Washington University study, �Investigate Opportunities for Lightweighting Vehicles Using Advanced Plastics and Composites.� The second is an Electricore study, �Mass Reduction for Light-Duty Vehicles for Model Years 2017-2015. The findings presented include that it is possible to lightweight vehicles and provide equivalent safety and that costs drive designers toward the use of advanced metals. The final remarks also identified needs: data for changing prevailing attitudes, demonstration programs to demonstrate efficacy of good designs, improved education, and improved predictive engineering.

Composite bearings of PTFE as the base material have been widely used for automotive parts. However, in recent years, due to downsizing, faster sliding speeds, and tendency to increase the bearing load with high performance, particularly for boundary lubrication conditions, the PTFE-based composite bearing is often worn, making it difficult to apply to some applications. A high strength polymer was selected as an alternative to PTFE base material, and the mechanical properties and performance in a start-stop test, reciprocating sliding test and seizure test were evaluated. Focusing on the characteristics of high strength, by applying a PEEK resin, in each evaluation, it was confirmed that superior performance was achieved compared with a conventional PTFE based composite bearing.

The need for light-weighting of automotive structures has spurred on a tremendous amount of interest in and development of low cost carbon fiber composite materials and manufacturing. This presentation provides a description of the commercial carbon fiber concept compared to traditional aerospace and specialty carbon fiber products. A specific update is presented on the development and commercialization of new low cost carbon fiber based on lignin / PAN precursor technology. The second focus of the presentation is on carbon fiber composite manufacturing processes, including carbon SMC, RTM, prepregs, and thermoplastic processes. Advantages and disadvantages of these processes are discussed, especially related to low cost manufacturing. Presenter George Husman, Zoltek Companies Inc.

This paper presents a new concept for a 100% plastic prototype automotive door panel. This concept has the potential of providing a weight reduction of up to 40% compared to conventional steel door panels, but with equivalent performance (static strength). This innovative technology can be used for a variety of exterior automotive parts. The concept includes a composite sandwich panel combination of GFRP (glass fiber reinforced polymer), and LACTIF®, which is expanded beads foam made from PLA (polylactic acid) and developed by JSP Corporation. This GFRP+LACTIF® composite design offers the following characteristics: Excellent environmental resistance Strong adhesion Equivalent static strength (vs. conventional door panels) Design flexibility This concept also offers an alternative to conventional steel door panel systems by using unsaturated polyester material of plant origin as part of the GFRP composite.

“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. In the episode “Composite Materials: Advanced Materials and Lightweighting” (30:20), Molded Fiber Glass Companies, known for its deep involvement in the creative development of the molded fiberglass process for the Corvette, demonstrates the manufacturing of sheet molded composite for fiberglass parts. Tanom Motors introduces the Tanom Invader, a blend between an automobile and a motorcycle made exclusively with composite materials. Finally, Euro-Composites demonstrates the manufacturing of honeycomb core material made out of aramid paper and phenolic resin used in aircraft structures.
