Document Type and Number:
WIPO Patent Application WO/2023/182432
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a thermosetting prepreg having good mechanical properties, and particularly having good handleability. The present invention relates to a thermosetting prepreg including: a fiber sheet; a first thermosetting resin composition that is impregnated in a central region in the thickness direction of the fiber sheet in a cross section perpendicular to the surface direction of the fiber sheet; and a second thermosetting resin composition that is impregnated in an outer region in the thickness direction of the fiber sheet in the cross section perpendicular to the surface direction of the fiber sheet, wherein the first and second thermosetting resin compositions each contain a thermosetting resin and a curing agent, and the equivalence ratio of the curing agent in the first thermosetting resin composition is greater than the equivalence ratio of the curing agent in the second thermosetting resin composition.
