Abrégé

Method of manufacturing a fibrous polymer composite material by compounding an organic fibrous component in particulate form with a mouldable polymeric component to obtain a flowable heated paste. The paste which is formed into an artefact which is caused or allowed to set to provide a solid matrix in which the particles of the fibrous component are dispersed. The method includes, prior to the setting of the polymeric component to form the matrix, the step of colouring the fibrous particles by impregnating them with a colouring material. The invention also provides a fibrous polymer composite material which includes an organic fibrous component in particulate form dispersed in a set polymeric component which is in the form of a matrix. The fibrous particles are coloured by means of a colouring material which is impregnated therein.
