REINFORCING FIBER BASE OF CURVED SHAPE, LAYERED PRODUCT EMPLOYING THE SAME, PREFORM, FIBER-REINFORCED RESIN COMPOSITE MATERIAL, AND PROCESSES FOR PRODUCING THESE

摘要

Provided are: a curved reinforcing fiber substrate (1) characterized by having a curved planar shape and by comprising reinforcing fiber yarns (2) arranged parallel with a direction along a circumferential direction (3) of the curved shape and auxiliary weft yarns (4) arranged in directions crossing a plurality of the reinforcing fiber yarns (2) each arranged in one direction of the circumferential direction (3); a curved reinforcing-fiber layered product using the substrate; a preform; a reinforced composite material; and processes for producing those. These can be provided as: a reinforcing fiber substrate curved along the longitudinal direction and arranged with reinforcing fibers along the curved shape in a desirable formation; a curved reinforcing-fiber layered product layered with at least one layer of the reinforcing fiber substrate and a process for producing the layered product efficiently in a short time; a preform using the layered product and a process for forming the preform efficiently; and a long-extended curved fiber-reinforced composite material and a process for producing the same.
