PURPOSE: To achieve wt. reduction and to hold strength by using polydicyclopentadiene as a matrix material and coating the matrix material with a synthetic resin or synthetic rubber containing a reinforcing fiber on the heat source side thereof to form a resin body.
CONSTITUTION: In a small ship, a hull member 1, a deck member 2, an engine hatch 6 and an air suction pipe 19 are formed by using polydicyclopentadiene as a matrix material. The inside being a heat source side of polydicyclopentadiene 22 is coated with a synthetic resin 24, for example, composed of a thermosetting resin such as an epoxy resin, a phenol resin or a urethane resin or a thermoplastic resin such as nylon and containing a reinforcing fiber. As the reinforcing fiber, a glass fiber is used for example. Said inside on the heat source side can be coated with synthetic rubber containing the reinforcing fiber.
