Fabrication and properties of HDPE/CF/CaCO3/PE-g-MAH quaternary composites

Abstract

In this research, carbon fiber (CF) was taken as reinforcing filler, nano calcium carbonate (CaCO3) was taken as toughener, maleic anhydride grafted polyethylene (PE-g-MAH) was taken as compatibilizer for high density polyethylene (HDPE) modification. Through orthogonal test, the influence of different amount of ingredient CF, CaCO3 and PE-g-MAH on the mechanical properties of the HDPE composites was researched. The optimal composition of the quaternary composites with the good toughness and high strength was obtained.
