Abstract: In this work, the optimum parameters for manufacturing technique of composite materials, based on various woods and polymers, are developed. These composite materials are intended to be used for furniture industry, knifes handles and figurine. Beech (Fagus silvatica), poplar (Populus alba) and rosewood (Pterocarpus indicus) were used as the object of research. Epoxy, styrene and tripropylene glycol acrylate were taken as monomers for making the composites. Several parameters of the manufacturing technique, including type of initiator for polymerization and its quantity, have been varied for optimum value. The manufacturing technique of composite material includes the extraction of wood by solvent to increase the size of pores and to obtain better filling of wood with the polymer. It has been established that methanol washes away the largest amount of substances from the wood. After extraction, the wood was exposed to vacuum drying and filled with initiator-containing monomer. Afterwards, the pressure was increased to improve the filling of wood with monomer. The final stage of technique was the increase of temperature and polymerization.
