Document Type and Number:
WIPO Patent Application WO/2013/046434
Kind Code:
A1
Abstract:
Provided are: a fiber-reinforced composite material, whereby it becomes possible to achieve all of excellent CAI, excellent ILSS and excellent bending fracture toughness simultaneously at high levels and it also becomes possible to keep the glass transition temperature of a resin material contained therein at a high temperature; a prepreg which can be used for the fiber-reinforced composite material; and a benzoxazine resin composition. The composition according to the present invention contains (A) a compound having a benzoxazine ring represented by formula (1) in the molecule thereof, (B) an epoxy resin, (C) a curing agent, (D) a toughness-improving agent, and (E) a polyamide 12 powder having a specific particle diameter at a specified ratio, wherein the component (D) is dissolved. (R1: a C1-12 linear alkyl group or the like, wherein H is bound to C located at O-position and/or P-position relative to a carbon atom on an aromatic ring to which an oxygen atom is bound in the formula.)
