Modifiers for Wood Plastic Composites (WPC)

impact strength decreases. Whereas an increase in the E-modulus is desirable, a reduction in the impact strength is certainly not. Through the use of SCONA coupling agents, which significantly enhance the bonding of wood fibers with the polymer matrix, mechanical properties such as bending strength and impact strength of the composite material are

The impact strength was found, in general, to increase when the samples were fractured at temperatures above 0oC and the impact strength decreased with the increase of fiber content. The impact energy absorption was highest of 270 KJm-2 with 47 vol% fiber when fractured at 60oC and it reduced to 130 KJm-2 at -60oC.
