【 摘 要 】

A lot of researchers are connected with partially green, biocomposites producing and investigations. Various of polymer matrices, mainly polyolefines, reinforcement-natural fibres and their combinations are used. Our studies are focused on high density polyethylene based biocomposites, containing investigation results of plywood production by-product sanding dust (PSD) exploitation properties (flexural strength and modulus, impact strength, microhardness, and water uptake). Also, the fluidity of composite melts was noted, but the fracture mechanism of the composites tryed to clear up with SEM studies. For wood plastic composites (WPC) modification coupling agents maleatedpolypropylene (MAPP) and polyvinylbutyral (PVB) were used.
