Abstract

This study investigates the impact of silane coupling grafting on the mechanical properties of load-bearing applications in a novel composite material composed of recycled PET bottle waste, thick core, and pineapple leaf fibre reinforced with vinyl ester. A comprehensive array of tests, including tensile, flexural, impact, interlaminar shear strength, flammability, and thermal conductivity tests, was conducted on both untreated and silane-treated specimens. Tensile tests revealed consistent strength improvements post-silane treatment (10.8%–19.4%), attributed to enhanced interfacial bonding. Flexural strength tests demonstrated notable gains (13.5%–20.8%), emphasizing the role of the PET core and pineapple fibre, with silane treatment optimizing adhesion. Impact test results displayed varied responses, suggesting complex interactions between components. Interlaminar shear strength consistently improved with silane treatment (9.68%–36.19%), showcasing collaborative effects. Flammability tests confirmed fire resistance in both composites, with nuanced thermal conductivity changes post-treatment (6.4%–18.6%). The study underscores the intricate interplay between the PET core, pineapple fibre, and silane treatment, collectively contributing to enhanced mechanical performance, fire resistance, and thermal behaviour in the composite materials. The integrated findings emphasize the intricate interplay between the recycled PET core, pineapple leaf fibre, and the effects of silane treatment, showcasing enhanced mechanical performance and potential suitability for load-bearing applications in the investigated composite material.

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
