EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition for a fiber-reinforced composite material as a matrix resin composition used for a self-adhesive prepreg for a face plate of a honeycomb panel, wherein the self-adhesive property of the prepreg can be improved and the workability and the quality of product appearance of the prepreg can be improved.

SOLUTION: The epoxy resin composition for the fiber-reinforced composite material contains an epoxy resin (A) which is in a liquid state at an ordinary temperature, a thermoplastic resin (B) which dissolves in the epoxy resin (A) at≥90°C, a thermosetting resin particle (C) which does not completely dissolve in the epoxy resin (A) at <90°C and has a softening point of≥120°C and a hardener (D).
