Abstract

A method of producing a moulded article comprising a thermoset polymer and particles of porous natural materials, such as wood materials, and uses thereof. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, and the particles are at least partially encased by the thermoset polymer. The method comprises the steps of providing a mould with two opposite pressing surfaces, said pressing surfaces defining a space between them; feeding particles of porous natural materials into the space between the pressing surfaces; advancing the surfaces towards each other to compress the particles in said space; feeding unhardened thermoset resin in liquid form into the mould so as to fill at least said space between pressing surfaces while keeping the particles compressed between the pressing surfaces; and curing the thermoset resin in the mould to provide a moulded composite article.
