Improvement of Mechanical Properties in Bamboo Maleic Anhydride grafted Polypropylene/Polypropylene Composite Enhanced with Resin Impregnation Method

摘要

Previously bamboo fiber reinforced PP composites was manufactures using Polyvinyl Alcohol(PVA) and Phenolic resin for Resin impregnated bamboo fiber with polypropylene(PP). Using 40% weight fraction of bamboo fiber in PP matrix, PVA impregnated composites with mean flexural and tensile strength 10% higher than untreated were produced. The PVA treatment improved the tensile and flexural strength of bamboo/PP composites and increased water absorption ratio. Next, matrix modified with Maleic Anhydride grafted Polypropylene(MAPP). For matrix PP mixed with 10% of MAPP. In this study, resin impregnation method dose not make different for mechanical properties of composites. Untreated and PVA, Phnolic resin impregnated mechanical properties was almost same. However; it can decreased water absorption PVA resin absorption bamboo fiber composites.
