Influence of filler proportion on mechanical and physical

on particle size (Hayes Seferis, 2001). Smaller particle size provides higher stiffness. Impact strength can be increased by smaller particle size or by adding impact modifier. In this case it might be necessary to increase particle size to decrease stiffness, because the reduction of filler wt% is not desirable.
