Investigation of Mechanical Properties of Jute Fiber Reinforced Low Density Polyethylene Composites

ABSTRACT

The environmentally friendly natural fiber reinforced polymers are increasingly taking attention in several industries like automotive and construction due to their properties such as being synthesized in desired properties, easy processing, non-corrosion, low weight, and low cost. In this study, untreated/alkali-treated/silane (1.5%)-treated/alkali+ silane treated jute fabrics (25%) were reinforced to low density polyethylene (LDPE) polymer (75%) with 1%, 3%, 5% and 7% maleic anhydride additives for composite production by using hot pressing method. Further, the effect of jute fabric surface treatments on the tensile strength, flexural strength, and impact resistance properties of the LDPE/jute composites were investigated with the absence/presence of maleic anhydride additives. The results indicate that the alkali/silane treatment of jute fibers led to more than 30% improvement in mechanical properties of the composite structures when reinforced to untreated LDPE, and the mechanical properties of the composites had more than 45% improvement by maleic anhydride addition to the polymer in ideal ratios with untreated jute reinforcement.

摘要

环保型天然纤维增强聚合物由于其合成性能好、加工方便、无腐蚀、重量轻、成本低等优点，在汽车、建筑等行业越来越受到重视. 本研究以未处理/碱处理/硅烷（1.5%）处理/碱处理/硅烷处理的黄麻织物（25%）为原料，采用热压法，分别加入1%、3%、5%和7%的马来酸酐添加剂，将其增强到75%的低密度聚乙烯（LDPE）聚合物中. 此外，研究了黄麻织物表面处理对LDPE/黄麻复合材料拉伸强度、弯曲强度和抗冲击性能的影响. 结果表明，黄麻纤维经碱/硅烷处理后，与未经处理的LDPE相比，复合材料的力学性能提高了30%以上，用未经处理的黄麻增强体与马来酸酐按理想比例添加到聚合物中，复合材料的力学性能提高了45%以上.
