MULTI-AXIS FABRIC, ITS PRODUCTION METHOD, PREFORM MATERIAL, AND FIBER-REINFOCED PLASTIC MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a multi-axis fabric which can easily produce a fiber-reinforced plastic molding of high surface smoothness. SOLUTION: In the multi-axis fabric, fiber-reinforced material layers 10a-10f of fiber-reinforced materials arranged in parallel to each other and heat weldable resin layers 12a-12f are laminated alternately. The fabric is produced by laminating fiber-reinforced material sheets with fiber-reinforced materials arranged in parallel to each other and nonwoven fabrics of heat weldable threads alternately while the fiber axis directions of the sheets are arranged or disarranged and heating and pressurizing the laminate. A preform material can easily be obtained by piling the multi-axis fabrics or the multi-axis fabrics and other fabrics and preforming them. COPYRIGHT: (C)2006,JPO&NCIPI
