<p>PURPOSE:To obtain fiber reinforced composite material, the volume reduction treatment and reclamation of which are easy, by a method wherein composite material layer is made of reinforcing fiber and resin such as epoxy resin or the like and resin layer is made of heat generating body to generate heat by flowing electric current therethrough and resin, which is decomposed or melted by the generated heat so as to laminatingly integrate both the layers. CONSTITUTION:As the reinforcing fiber used in composite material layer 1, both inorganic fiber and organic fiber are favorable. The composite material layer 1 is produced by solidifying the reinforcing fiber with highly rigid resin such as epoxy resin or the like. The resin layer 2 is made, for example, of polyolefin-based resin and nickel chrome resistance wire. The composite material layers 1 and the resin layers 2 are laminated to each other into an integral body. By flowing electric current in the heat generating body of the resin layers 2 in the obtained fiber reinforced composite material, the polyolefin-based resin is melted, resulting in separating the composite material layers 1 from each other and consequently allowing to easily compress, cut and grind the fiber reinforced composite material. Further, as the heat generating body, short electrically conductive fiber or the like can also be used.</p> |
