Title:
PREPREG AND CARBON FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/173953
Kind Code:
A1
Abstract:
The present invention provides: a prepreg that yields a carbon fiber-reinforced composite material having exceptional mode I interlayer toughness, mode II interlayer toughness, and tensile strength; and a carbon fiber-reinforced composite material. A prepreg including the following components [A]-[C], wherein a resin composition including components [B] and [C] has a higher-order structure derived from a diffraction angle 2θ = 1.0-6.0° observed by x-ray diffraction after curing. [A]: Carbon fibers, [B]: epoxy resin, [C]: curing agent of [B]
