Jr. Attorney, Agent or FirmAbstractA structural member is fabricated from a mixture of scrap particles of thermoplastic wire and cable insulation, wood particles, comminuted paper, sawdust, and a suitable resin binder. The fabrication procedure is carried out by initially forming a mixture of reclaimed thermoplastic wire or cable insulation, a thermosetting binder, and one or more wood like fillers, such as wood chips, comminuted paper and sawdust and mold release agent. The mixture is then placed in a mold and is subjected to heat and pressure to form a structural member. | |
