Blending of the C120 and HB120 into polypropylene PP at a loading of 40%w/w has been achieved by twin-screw extrusion. Compression moulded samples were machined into a conical tag used for die drawing. 2-stage orientation was done successfully to 3 and 10 lambda. The orientation of the WP structure has resulted in an increase in tensile and bending properties and decrease in the thermal expansion. The macroscopic density of 890 kg/m3 and aspect ratio in the rage from 9.1 to 8.1 of the WP were evaluated giving the possibility to use the Cox-Krenchel model to prediction the composite stiffness. For the isotropic C120 PP composite the C120 indicated 2D orientation giving the theoretical modulus of 1.9GPa which is in excellent agreement with the experiment value of (1.9 +/-0.2)GPa. For the oriented composites the orientation function eta0 used in the Cox-Krenchel model has not understated the moduli. For this reason, Wards orientation function I was used to link the modulus with the molecular and particles orientation. The function I is also a very successful tool to predict the stiffness of the WPC in oriented states. The theoretical moduli are 3.9GPa and 8.1GPa for the 3 lambda and 10 lambda materials respectively while the experimental values are (3.2 +/-0.3) and (8.2 +/-0.3)GPa.
