The focus of this study has been to fully describe the mechanical properties and
behaviour of an extruded Wood Plastic Composite product. The use of plasturgy technologies
for the elaboration of lignocellulose reinforced composites raises fundamental questions
about the behaviour of these materials. Mechanical properties of a composite depend
generally on fibre content, fibre/matrix interface link or added coupling agents.
Processes play an important role on the reinforcement distribution in the matrix. The main
purpose of this paper is to describe mechanical behaviour of WPC composites which are
manufactured using an extrusion process. So, complete set of experiments has been
realised: tensile, compressive, bending and shear tests. Longitudinal direction refers to
extrusion process directional flow and transverse direction specimens have been tested.
Mechanical performances of Wood Plastic Composites depend also on the link of fibre/matrix
interface, fracture surface has been analysed using an optical microscope.
