Abstract

The present study investigates mechanical, thermal, and tribological characteristics with the influence of novel composite material of perforated polyethylene terephthalate (PET) polymer, distinct natural fibre, and vinyl ester matrix produced by compression moulding technology. The primary objective of this study is to identify and influence the strength of vinyl ester resin bonding features of three distinct natural fibre sources: banyan, snake grass, and pineapple with recycled PET plastic bottles polymer composites. The natural fibre is undergoing chemical treatments using NaOH (7% alkali) in order to remove the impurities and enhance the strength of the composite material. The mechanical characteristics of the produced composites (PC1, PC2, PC3) were assessed using tensile, flexural, and impact tests. The study also encompasses an investigation of thermogravimetric analysis conducted on natural fibre/PET/vinyl ester composites, demonstrating the impact of distinct fibre with PET polymer on thermal characteristics. Moreover, specific wear rate and coefficient of friction analysis explore the distinct character of developed composites. Using natural fibre reinforced/vinyl ester composites in conjunction with PET offers a promising avenue for achieving lightweight structural applications due to the PET composite's favourable mechanical properties and heat resistance.

穿孔废PET改性天然纤维复合材料力学、热学和摩擦学特性的协同效应

本研究考察了穿孔聚对苯二甲酸乙二醇酯（PET）聚合物、独特的天然纤维和乙烯基酯基复合材料通过压缩成型技术生产的机械、热和摩擦学特性的影响。本研究的主要目的是确定并影响三种不同天然纤维来源：榕树、蛇草和菠萝与再生PET塑料瓶聚合物复合材料的乙烯基酯树脂结合特性的强度。天然纤维经过氢氧化钠（7%碱）的化学处理，以去除杂质，提高复合材料的强度。制备的复合材料（PC1、PC2、PC3）的力学特性通过拉伸、弯曲和冲击试验进行评估。该研究还包括对天然纤维/PET/乙烯基酯复合材料进行的热重分析调查，展示了不同纤维与PET聚合物对热特性的影响。通过比磨损率和摩擦系数分析，探索了复合材料的独特特性。由于PET复合材料具有良好的机械性能和耐热性，将天然纤维增强/乙烯基酯复合材料与PET结合使用，为实现轻量化结构应用提供了一条有希望的途径。
