ABSTRACT

The growing interest in eco-friendly materials motivates the use of natural fibers in composites. This study investigated the influence of jute fabric layer reinforcement on the mechanical and thermal properties of polypropylene (PP) modified with 20% and 30% weight contents of maleic anhydride (MAPP). Results showed improved mechanical properties, especially for the composite with 2 layer jute fabrics and 30% of MAPP, which had an increase of about 100% in tensile and 45% in flexural strength. This composite also presented advantageous thermal properties for processing. Statistical analyses of mechanical properties revealed a significant interaction between jute and MAPP, leading to improved fiber/matrix adhesion.

摘要

对环保材料日益增长的兴趣促使天然纤维在复合材料中的使用。本研究调查了黄麻织物层增强对聚丙烯 (PP) 的机械和热性能的影响，聚丙烯 (PP) 用 20% 和 30% 重量含量的马来酸酐 (MAPP) 改性。结果表明，机械性能得到改善，特别是对于具有 2 层黄麻织物和 30% MAPP 的复合材料，其拉伸强度和弯曲强度分别提高了约 100% 和 45%。这种复合材料还呈现出有利的加工热性能。机械性能的统计分析揭示了黄麻和 MAPP 之间的显着相互作用，从而提高了纤维/基质的粘合力。
