    摘要: The invention relates to a method for making light-weight dimensionally stable wood-thermoplastic composite material composed of wood chips and a thermoplastic polycaprolactone. The manufacturing process of composite material comprising the steps of compounding virgin materials with single-screw extruder and production of uniform homogeneous plate-like composite with calendering apparatus. The calendering process comprises of several cycles, folding, cooling and reheating steps. During the gentle manufacturing process fragile wood chips maintain their 3-D structural properties in polymer matrix resulting light, mechanically strong wood-plastic composite.

    摘要: The present invention concerns a novel low-temperature thermoplastic wood-biopolymer composite comprised of small wood particles and a polycaprolactone (PCL) homopolymer for use in medical procedures including orthopedic casting or splinting. The material is made from a thermoplastic composite that softens when heated to approximately 60° C., after which it can be formed directly on the patient. The composite then retains its shape as it cools down. The material is composed of epsilon caprolactone homopolymer reinforced with discontinuous short length wood particles.
