Microcosmic morphology investigation of chlorinated polyethylene/AO 2246/seven-hole hollow polyester fiber composites

A series of ternary composites were prepared from chlorinated polyethylene(CPE),2,2′-methylene-bis-(6-tert-butyl-4-methyl-phenol)(AO 2246) and seven-hole hollow polyester fiber(SHPF).The cross-section and internal microcosmic morphologies of the composites were investigated by means of scanning electron microscope(SEM) and three-dimensional video microscope.The effect of SHPF on AO 2246 crystallization and SHPF distribution inside the composites was analyzed.The results showed that SHPF acted as an induced nuclear for the crystallization of AO 2246 in the forming process of the composites.The induction enhanced significantly with increasing of SHPF content,and a large number of three-dimension granular crystallizations were formed,then most of the crystallizations were coated on SHPF surface.This resulted in the forming of crystallization-fiber network structures inside the composite even thought when SHPF content was small.
