ABSTRACT:
A process for making a laminated structural member is disclosed in which the member is fabricated with one layer of sheet material such as plywood or fiberboard and an adjacent layer bonded thereto and formed from a mixture of scrap particles of thermoplastic wire and cable insulation, wood particles, comminuted paper, sawdust, and a suitable resin binder. The fabrication process is carried out by initially forming a mixture of reclaimed thermoplastic wire or cable insulation, a thermosetting binder, a wood-like filler, and a mold release agent. The mixture is then placed in a mold with the sheet material and subjected to heat and pressure to form a laminated structural member.
