Abstract:

The overall objective of the program is to demonstrate by analysis, fabrication, and testing of conical sections of ultra high-modulus graphite epoxy structures that the material is applicable on future high-performance interceptors. GY70934 epoxy Fiberites HY-E-1534 ultra-high-modulus unidirectional tapes were used in construction of the basic shell structure in the subscale development program. Ten subscale conical frusta representing the basic shell were fabricated and supplied to AMMRC. Testing at Martin Marietta confirmed their analytically predicted performance and enabled the program to investigate methods of fabricating strong, stiff end reinforcements for field splicing of missile sections. Twelve subscale cones were fabricated and supplied to AMMRC to evaluate three types of interleaved titanium foil joint concepts.
