<p><P>PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin plate improved in flexural strength in the longitudinal direction. <P>SOLUTION: The fiber-reinforced resin plate is obtained by a process in which a plurality of fiber-reinforced resin rods 1, 1, etc., are arranged in parallel, at a prescribed intervals, and in the longitudinal direction on a reinforcing fiber structure 2, another reinforcing fiber structure 2 is arranged on the upper surfaces of the resin rods 1, 1, etc., a prescribed spot between the resin rods 1 and 1 is sewn with a thread 3 so that the resin rods 1, 1, etc., are held and integrated by the reinforcing fiber structure 2 and 2, the whole obtained integrated structure is impregnated with a resin, and the resin is cured. In the reinforcing fiber structure 2, preferably, a layer A in which all the reinforcing fibers are arranged in a constant direction and a layer B in which all the reinforcing fibers are arranged in another constant direction are laminated together. <P>COPYRIGHT: (C)2004,JPO</p> |
