Paper Title:
Mechanical Force Induced Grafting Effect on Strengthening HDPE/GF Composites with Maleic Anhydride
  Abstract

Grafting of maleic anhydride (MAH) onto high density polyethylene (HDPE) was carried out in melt state through the mechanical force initiation caused by high-speed rotation of the twin-screw, investigating its functional reaction and the grafting degree influenced by the rotation of the twin-screw, observing the influence on its mechanical property. The results showed that the increase of grafting degree made the interface phase produce a firm chemical coupling, which improved the tensile-strength and flexural strength of the composites. The produced interfacial stress from the shrinkage of specimen melts in injection molding process can strain-induce the forming of the extended-chain crystals in the matrix and obviously improve the notched impact strength of the composites.
