Abstract

In order to evaluate the mechanical properties of T800H/3633 CFRP woven laminates for cryogenic tankage in RLV, tensile and in plane shear tests were performed at room temperature, liquid nitrogen temperature (77 K) and liquid helium temperature (4 K). The tensile tests were conducted in accordance with ASTM D 3039 and JIS K 7073. Tensile strength and modulus were evaluated for both the warp and fill directions. A problem was encountered with obtaining acceptable failure of the specimens. We could not achieve failure in the test section. This problem was avoided by using dogbone shaped specimens. A two dimensional finite element analysis was also used to study the stress distributions within the specimens and to interpret the experimental measurements. The in plane shear modulus and shear strength were measured by tensile tests on the + 45 specimens (ASTM D 3518 and JIS K 7079). The effects of temperature on the stress strain responses in tension and in plane shear are examined. Fracture topography of specimens is also investigated and interpreted.
