development2. Directives are established through workshops where the PNGV technical teams and vehicle engineers identify potential materials and applications. Challenge tables have been created to prioritize developments needed to support technology selection in 1997. These tables compare present state-of-the-art technologies with PNGV requirements. A series of workshops has been held with materials suppliers to identify materials research projects in response to the developments identified in the challenge tables. Workshop participants are encouraged to submit white papers outlining their proposed research. Opportunities may exist to leverage materials developments in non-automotive areas —notably in the aerospace sector—in pursuit of PNGV goals. Advanced alloys, ceramics, and composite materials developed for a range of high-performance applications may offer potential for automotive use.

MATERIALS OPTIONS

Three candidate materials have now been identified for body structure; namely, steel, aluminum, and graphite fiber-reinforced, polymer-matrix composites (GFRP). Many opportunities exist to develop improved
