| 概要 | Vinylester resin (VER) composed of bisphenol-A-based epoxy methacrylate and styrene was cured finally at 120 degree C with methacryl-substituted polysilsesquioxane (ME-PSQ). The dynamic mechanical and thermal properties of the VER/ME-PSQ hybrid composites were investigated as compared with crosslinked VER (C-VER) and VER/phenyl-substituted polysilsesquioxane (Ph-PSQ) composite cured at the same condition. As a result, the VER/ME-PSQ hybrid composites showed much higher storage modulus (E') at rubbery state than C-VER and the VER/Ph-PSQ composite. The E' of the composites increased with increasing ME-PSQ content. Also, coefficient of thermal expansion of the hybrid composites decreased with increasing ME-PSQ content. The Tg and 5% weight loss temperature of the VER/ME-PSQ composites were almost the same as those of C-VER and the VER/Ph-PSQ composite. |
