Abstract

The compression properties of three-dimensional (3Dim) and five-directional (5Dir) braided/epoxy resin composites and laminated resin composites at room temperature, 90℃, 120℃, 150℃, and 180℃ and heating for 15 min, 600 min, 1800 min, and 3000 min were studied. The effect rules of different temperature and different heating time on the compression property of these composites were comparatively analyzed. Macro-fracture morphology and SEM micrographs were examined to understand the deformation and failure mechanism. The significant decrease for the compression strength of laminated composites at high temperature is due to the delamination of the laminated composites because of the resin damage, which shows that structures of reinforcements have significant influences on compression property of resin composites at high temperature..
