Title:
MULTIAXIAL TEXTILE RESIN BASE MATERIAL AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/031834
Kind Code:
A1
Abstract:
A multiaxial textile resin base material comprising a thermosetting resin (B) impregnated in a multiaxial textile base material laminate. The multiaxial textile base material laminate includes fiber bundle sheets in which a unidirectionally aligned fiber bundle is stitched by a stitching yarn composed of a thermoplastic resin (A), the fiber bundle sheets being stacked at different angles, and is traversed in the thickness direction by the stitching yarn that is separate from the laminate, wherein the stitching by the separate stitching yarn runs back and forth while being disposed at a predetermined interval along the length direction. The thermoplastic resin (A) constituting the stitching yarn has a softening point, and the softening point is higher than a resin impregnation temperature for the thermosetting resin (B). Provided is a multiaxial textile resin base material that has an excellent resin impregnability, a high durability (hydrolysis resistance, resistance to thermal deterioration), excellent mechanical properties for composite materials, and an improved compression-after-impact (CAI).
