Title:
THERMOPLASTIC COMPOSITE WOOD MATERIAL
Document Type and Number:
WIPO Patent Application WO2002022981
Kind Code:
A3
Abstract:
A composite material comprises a first wood component (102) of substantially axially aligned wood chips having a first size range and being distributed throughout the composite material in a first discontinuous phase (602), a second wood component of wood particles (104) having a second size range and being distributed between the wood chips in a second discontinuous phase (604), the second size range being distinct from the first size range and having substantially smaller values than the first size range, and a thermoplastic polymer component encapsulating the wood chips and the wood particles and forming a continuous phase extending throughout the composite material. The wood chips constitute from about 100 to about 0 weight percent of a total weight of the first and second wood components and the wood particles constitute from about 0 to about 100 weight percent of the total weight of the first and second wood components. The first and second wood components together constitute from about 90 to about 50 weight percent of the composite material. The thermoplastic polymer component constitutes from about 10 to about 50 weight percent of the composite material.
