    The overall objective of this research is to develop high-performance wood polymer composites (WPCs) and novel wood-WPC hybrid materials for joinery products.These WPCs and hybrids represent new, innovative and eco-efficient biocomposites for targeted product profiles with improved mechanical performance.The composites were prepared by blending hardwood (birch) or softwood (a mixture of pine and spruce) chips with polypropylene matrix.The percentage of the wood material in the blends was 60%.Coupling agents (maleated polypropylene) and other additives were added in the blends in small quantities.Some material combinations were also treated with additives, such as UV pigments and nanomers, in order to improve the UV- and abrasion resistance of the samples.An injection molding technique was used to make test samples from the different material combinations.
