Document Type and Number:
Japanese Patent JPH08127663
Kind Code:
A
Abstract:

PURPOSE: To obtain a carbon fiber-reinforced polyfunctional maleimide-based resin prepreg capable of stably imparting high toughness to carbon fiber- reinforced polyfunctional maleimide-based composite materials without impairing their heat resistance.

CONSTITUTION: This prepreg with carbon fibers as reinforcing fibers and a polyfunctional maleimide resin as matrix resin has on its surface a thermoplastic resin molding material. In this prepreg, the polyfunctional mleimide resin is made from, as the essential components, (1) a polyfunctional maleimide compound and (2) an alkenylphenol and/or alkenylphenol ether compound, and ≥50wt.% of the component (1) exists in the form of solid particles in the resin and meltable at the temperatures at or below the curing temperature of the resin.
