EPOXY RESIN COMPOSITION FOR RESIN TRANSFER MOLDING OF FIBER-REINFORCED COMPOSITE MATERIAL, FIBER-REINFORCED COMPOSITE MATERIAL, AND METHOD FOR PRODUCING SAME
摘要:
An epoxy resin composition for RTM molding of a fiber-reinforced composite material includes [A] to [D] below, wherein [A]/[B], which is a blend mass ratio of [A] to [B], is in the range of 55/45 to 95/5: [A] a multifunctional epoxy resin that is liquid at normal temperature or has a softening point of 65° C. or lower, the multifunctional epoxy resin being at least one selected from phenol novolac epoxy resin, cresol novolac epoxy resin, and triphenylmethane epoxy resin; [B] an alicyclic epoxy resin; [C] an acid anhydride curing agent; and [D] a curing accelerator.
