AbstractThe objective of the research is to screen lightweight composite manufacturing methods for rotorcraft airframes that are lower cost than the autoclave curing process. The suitability and durability of materials used for rotorcraft airframe parts must be established by approved tests to ensure the strength and other properties are applicable to the specific structure's loads and environments. TRI/Austin will conduct screening tests on composite materials to evaluate new material systems under worst-case operational environments and loading conditions. These results will be used for future analysis of rotorcraft airframe designs, with emphasis being placed on Boeing's V-22 airframe. This test program will be designed to help identify the most promising new material systems while keeping testing to a minimum. The screening test matrix will involve key static tests that will provide sufficient data to assess mean values of stiffness and strength at the extreme operational conditions. Screening will consist of tensile, compression, shear, water absorption, chemical resistance, and fatigue tests. The results from these tests will be used to verify the performance of the composite material and to augment the design and analysis of future composite airframe structures.
