Problems solved by technology

However, epoxy resin lacks heat resistance, and sometimes cannot fully meet the heat resistance requirements in high-temperature environments such as exceeding 180°C.
In addition, although polyimide, which is known as a heat-resistant resin, has excellent heat resistance, it may be very difficult to melt impregnate when producing prepregs, and the viscosity and drapability of the produced prepregs may be completely lacking.

Abstract

Provided are: a resin composition which exhibits a good balance between the heat resistance and handleability of the composition and the tuckability and drapability of a resulting prepreg, and which causes little resin flow during the molding of the prepreg; a prepreg made using the resin composition; and a fiber-reinforced composite material. A resin composition which comprises a maleimide compound, a diallylbisphenol A, and a diallyl isophthalte polymer; a prepreg obtained by impregnating a reinforcing fiber with the resin composition; and a fiber-reinforced composite material obtained by molding the prepreg.

Description

technical field [0001] The present invention relates to a resin composition, a prepreg using the resin composition, and a fiber-reinforced composite material. Background technique [0002] As a matrix resin used in fiber-reinforced composite materials, epoxy resin is the mainstream. However, epoxy resins lack heat resistance, and sometimes fail to satisfy heat resistance requirements in high-temperature environments exceeding 180° C., for example. In addition, polyimide known as a heat-resistant resin has excellent heat resistance, but it may be very difficult to melt impregnate when producing a prepreg, and the stickiness and drapability of the produced prepreg may be completely lacking. Therefore, a maleimide compound having a good balance between heat resistance, tackiness and drapability of a produced prepreg has attracted attention as a matrix resin for fiber-reinforced composite materials (Patent Documents 1 and 2). [0003] In addition, Patent Document 3 describes a...
