Composite materials based on wood and thermoplastic material, and process for preparing them.

摘要

A new composite material made up of wood dispersed in a thermoplastic material forming a matrix, characterised in that: - the wood is present in the said material in a proportion of 15 to 50 % by weight relative to the final material in the form of fibrous particles of mean diameter of between approximately 0.1 and approximately 1 mm and not exceeding 10 times the said diameter in length, - and the final material has a density which is from 10 to 20 % lower than the density of the thermoplastic material forming the matrix; and a process for preparing the said material. e
