PURPOSE: To provide an excellent reinforcing effect by a method wherein laterally arranged carbon fiber yarns are organized in a gauge elastic webbing state by means of two reinforcing fiber yarns, and the reinforcing fiber yarns are hardened by a thermoplastic resin to form a lattice-form substance. CONSTITUTION: Reinforcing fiber yarns 3 in a lateral direction formed of a polyaramide fiber, a carbon fiber, and a glass fiber are organized in a gauge elastic webbing state by means of two reinforcing yarns 2a and 2b in a vertical direction. The reinforcing fiber yarns 3, 2a, and 2b are impregnated or covered with a thermoplastic resin solution or molten thermoplastic resin and by curing the thermoplastic resin, a lattice-form substance 1 with a lattice mesh size of approximate 5-150mm is formed. The lattice-form substance 1 is then applied on forms and bent under heating. The bending is effected at a non-intersection part between the reinforcing fiber yarns 2a, 2b, and 3 in a vertical direction and a lateral direction. This constitution and method prevent the occurrence of a warp and peel at a joint.
