Wood-polymer composites flexural properties

The effect of wood species on the wood-polymer interface and on properties of WPCs has received little attention in the literature. Stark and Berger [13] evaluated the effect of ponderosa pine, loblolly pine, maple, or oak on the mechanical properties of polypropylene WPCs. In general, WPCs made with maple or oak exhibit slightly better tensile and flexural properties and heat deflection temperatures than either of the pines. Composites elaborated with coconut flber and polyurethanes have shown good results. Coconut flber acts as reinforcement and active part of the matrix system, improving the interface...
