Abstract
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.
Claims24
A composite material, comprising a first component formed by a polymer and a second component formed by a reinforcing material, wherein
- the first component comprises a thermoplastic polymer selected from the group of biodegradable polymers and mixtures thereof, and
- the second component comprises a woody material of platy wood particles having a smallest dimension greater than 0.1 mm.
(canceled)
A composite material comprising a first component formed by a polymer and a second component formed by a reinforcing material, wherein
- the first component comprises a thermoplastic polymer selected from the group of biodegradable polymers and mixtures thereof, and
- the second component comprises a woody material, the majority of the woody material being made up of wood particles greater in size than powder.
