EPOXY RESIN COMPOSITION, PREPREG, AND CARBON-FIBER-REINFORCED COMPOSITE MATERIAL |
摘要 |
Provided are: an epoxy resin composition which enables the production of a carbon-fiber-reinforced composite material having excellent tensile strength and compressive strength and suitable as a material for structures; a prepreg; and a carbon-fiber-reinforced composite material. An epoxy resin composition characterized by comprising at least [A] an epoxy resin having a structure represented by formula (1), [B] an epoxy resin having at least one amine-type glycidyl group or at least one ether-type glycidyl group and having a liquid form at 40° C. and [C] a curing agent; and a prepreg and a carbon-fiber-reinforced composite material, each produced using the epoxy resin composition.;;(In the formula, R1 to R4 independently represent at least one atom or group selected from the group consisting of a hydrogen atom, an aliphatic hydrocarbon group having 1 to 4 carbon atoms, an alicyclic hydrocarbon group having 4 or less carbon atoms, and a halogen atom.) |

1. An epoxy resin composition comprising at least the following components [A], [B], and [C]:
[A] epoxy resin having a structure as represented by chemical formula (1), wherein R1 to R4 represent at least one selected from the group consisting of a hydrogen atom, aliphatic hydrocarbon group containing 1 to 4 carbon atoms, alicyclic hydrocarbon group containing 4 or less carbon atoms, and halogen atom, [B] epoxy resin having at least one amine type glycidyl group or ether type glycidyl group and being liquid at 40° C., and [C] curing agent. |
