CHARACTERIZATION OF KNITTED FABRIC REINFORCED PP/PP AND GF/PP COMPOSITES

摘要

This paper reports an experimental study to characterize impact behaviors of PP/PP and GF/PP composites. The plain knitted PP and GF textile fabric were combined with homo-PP matrices to fabricate flat composite panels using injection compression molding technique. The molding temperatures of the resin and the mold were varied in order to study the effects of processing conditions on the impact behaviors. It was found that at the low molding temperature, due to the integrity of PP fabric was preserved, even PP/PP composite showed the similar impact resistance as compared with GF/PP composite.
