【 摘 要 】

The purpose of this study was to generate the material database for carbon and glass composite panels created by the SCRIMP process. The materials tested were glass/polyester composites, two types of carbon/polyester composites, and carbon and glass hybrid composites. The differences between the two types of carbon/polyester, which we call Type 1 and Type 2, are the ply thickness (.037 inch/ply and .048 inch/ply) and slightly different treatment of polyester resin. The tests that were performed for this study are four-point-bending tests, tension tests, panel warping tests, and beam bend-twist coupling tests. The material properties of interest were basic longitudinal and transverse stiffness and strength, residual stress due to curing, and the effect of bend-twist coupling. The bend-twist coupling is a feature that can be added to the composite laminate or structure, such that when it is bent, it will also twist.
