Abstract
In this research, effect of filler and coupling agent on mechanical properties of composites has made from sander dust of particleboard-polypropylene were investigated. The possibility of using high percentage of filler with polypropylene was studied. Three weight percentages of filler namely 40, 55 and 70 percents were chosen. MAPP as coupling agent for increasing quality of adhesion between filler and matrix was used namely 2 percents. Tensile strength, bending strength and toughness were measured. The results showed that with increasing filler, modulus of bending was improved. But tensile stress, tensile modulus, tensile strain, bending stress and toughness was decreased. Also, increasing coupling agent resulted in improving tensile stress, tensile strain, bending stress, modulus of bending and toughness and decreasing tensile modulus.
