PURPOSE: To provide the reinforced fiber sheet arranged in one direction, while when the construction such as a bridge, etc., is reinforced by fiber-reinforced plastic, the reinforcement may be carried out with favorable workability at reinforcing site, its reinforced strength can be improved and it is preferably used in the manufacture of a small boat, etc., by hand lay-up.
CONSTITUTION: A reinforced fiber sheet 1 is composed of the substrate sheet 2 which is provided with adhesive layer 3 and has mold release property and resin-unpermeability and the reinforcing fiber 4 arranged in one direction on the substrate sheet 2 through te adhesive layer 3 and stuck thereto. Accordingly, after the reinforcing fiber 4 has been impregnated with the matrix resin of room temperature-curing type and has been stuck to the position to be reinforced at reinforcing site, since the matrix resin is cured by leaving it as it is and fiber reinforced plastic is made, the operational propety of reinforcing process is excellent, and since the reinforcing fiber 4 is arranged in one direction, its reinforced strength is improved.
