In the materials area, the Partnership listed eight areas of major achievement in its presentations to the committee on January 26, 2012.32 These were as follows:
• Completed design and manufacturability assessment of a magnesium front-end structure.
• Completed design, tooling, fabrication, and testing of a one-piece composite underbody, saving 11.3 kg.
• Optimized engineering and manufacturing processes for advanced high- strength steel (AHSS).
• Developed a process for warm forming of aluminum and magnesium sheet.
• Enhanced the formability of aluminum at room temperature.
• Demonstrated a conversion technique for low-cost textile precursor for carbon fiber.
• Improved performance of AHSS welds.
• Developed a unique process for producing low-cost highly ductile magnesium sheet.
Response to Recommendations from the Phase 3 Review
Three recommendations on materials were made in the NRC Phase 3 report (NRC, 2010, pp. 108-109). The Partnership responses are shown below as “Updates.”
NRC Phase 3 Recommendation 3-22. The materials technical team should develop a systems-analysis methodology to determine the currently most cost-effective way for achieving a 50 percent weight reduction for hybrid and fuel cell vehicles. The materials team needs to evaluate how the cost penalty changes as a function of the percent weight reduction, assuming that the most effective mix of materials is used at each step in the weight-reduction process. The analysis should be updated on a regular basis as the cost structures change as a result of process research breakthroughs and commercial developments. [NRC, 2010, p. 108.]
Updates: DOE FY 2011 solicitation results for the multimaterial vehicle car (50 percent lighter than a midsized vehicle, design, build, and validate):
• Award to Vehma (Magna International)—project started in November 2011.
