250 yarns per 25 mm are prepared in parallel in a sheet form, and the sheet yarns are crossed at right angles so that each fiber axis direction of the laminated sheet yarns is a glass fabric (density 15 x 16 yarns/inch). ) was placed perpendicularly to the warp and weft threads at an angle of approximately 45°. “Kevlar” (registered trademark) manufactured by DuPont is used in the laminate.
Using the fiber as a sewing thread, the glass cloth was sewn in the warp direction using a sewing machine (manufactured by Seiko Corporation, model LLW-8L). The sewing conditions were lock stitch, stitch interval 15 mm, and stitch 1 mm. The three-layer laminate thus obtained was subjected to a conventional molding process using an epoxy resin to obtain a molded product. The molding material thus obtained was strong and exhibited highly isotropic properties.
