EPOXY RESIN COMPOSITION, SEMI-CURED EPOXY RESIN COMPOSITION, RESIN SHEET AND PREPREG

摘要

Provided are an epoxy resin composition, a resin sheet which is a sheet-shaped molded body of the epoxy resin composition, a prepreg having a fiber substrate and the epoxy resin composition impregnating the fiber substrate, and a semi-cured epoxy resin composition, comprising component (A): an epoxy resin having a mesogenic skeleton, component (B): a curing agent comprising a novolac resin wherein a divalent phenolic compound has been turned into a novolac, and component (C): an inorganic filler, wherein monomeric components in the curing agent of component (B) are at most 0.6 mass% of the entire resin content in a semi-cured state (B stage).
