EPOXY RESIN COMPOSITION, PREPREG, AND METHOD FOR PRODUCING MOLDING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve such a problem in conventional technique that a mold release agent has to be applied to a mold almost every time upon molding in order to secure sufficient mold releasability, so that a molding cycle is prolonged due to effort and time for applying the mold release agent. SOLUTION: The epoxy resin composition contains 0.1-10 pts.mass of an epoxy resin having structure (I) relative to 100 pts.mass of an epoxy resin. The prepreg comprises the epoxy resin composition and reinforcing fibers. In a method for producing a molding, the prepreg comprising the epoxy resin composition and the reinforcing fibers is heated and pressurized for 1-20 minutes in a preheated mold and cured.
