Abstract
A compressed article formed by a composite material comprising a thermoset polymer and a wood material, a method of producing the same and the use of the novel articles. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, wood chips which are at least partially encased by the thermoset polymer, said article having a water absorbency of less than 1% by weight upon immersion into water over a time period of at least 168 h at room temperature. The articles can be used in structures that are frequently contacted with water.

20. A method of producing an article comprising:
-
blending wood chips with a liquid formed by unhardened thermoset resin at a weight ratio of 1;
100 to 60;
100 to obtain a uniform mixture;transferring the mixture into a compression mould having a receiving surface corresponding to an outer surface of the compressed article; and moulding the mixture in said mould under compression to form a compressed article having at least one surface formed against the receiving surface. - View Dependent Claims (21, 22, 23, 24, 27)
