Description

For high density polyethylene (HDPE)/CaCO3 composites, CaCO3 inclusion influenced the mechanical properties significantly. The impact fracture behavior of HDPE depends on the diameter of the CaCO3 particles. When investigating HDPE showed ductile fracture in impact testing, CaCO3 inclusion increased tensile yield stress and impact strength. Especially, the CaCO3 having 1.4 µm of diameter improved significantly the impact strength. On the other hand, when the HDPE showing brittle fracture at impact test was used, CaCO3 inclusion decreased tensile yield stress and impact strength. Thus, during impact testing, CaCO3 inclusion varied ductile HDPE to be more ductile, while, in contrast, brittle HDPE became more brittle.
