Abstract

Fibre-reinforced polymer composites (FRPCs) are widely used in structural and semi-structural applications across various engineering fields. While previous drilling research on FRPCs has largely focused on optimising processing conditions to enhance hole quality, limited attention has been given to the interplay between drilling parameters, material properties, and production methods. This study investigates high-speed drilling of silane-treated pineapple fibre and waste micro rubber-reinforced vinyl ester composites under thermal (50 °C for 7, 14, and 30 days) and water ageing (room temperature for 7, 14, and 30 days) conditions. Post-drilling analysis examined common defects such as fibre delamination, matrix cracking, degradation, fibre swelling, burning, and edge tearing using an optical microscope. Results show that silane surface treatment with 3-aminopropyltrimethoxysilane significantly reduced drilling-induced damage under temperature ageing conditions, demonstrating its effectiveness in improving composite durability and machinability. These highly stable treated composites could be used in automotive, aerospace, and structural applications where large drill holes and fasteners are needed to be fixed to join the structural member temporarily and permanently.

水和温度老化对硅烷表面处理菠萝纤维-废微橡胶乙烯基酯复合材料的影响

纤维增强聚合物复合材料（FRPCs）广泛应用于各种工程领域的结构和半结构应用。虽然之前关于frpc的钻井研究主要集中在优化加工条件以提高孔质量上，但很少关注钻井参数、材料性能和生产方法之间的相互作用。本研究研究了硅烷处理菠萝纤维和废弃微橡胶增强乙烯基酯复合材料在热（50°C， 7、14和30天）和水老化（室温，7、14和30天）条件下的高速钻孔。钻后分析使用光学显微镜检查常见缺陷，如纤维分层、基体开裂、降解、纤维膨胀、燃烧和边缘撕裂。结果表明，3-氨基丙基三甲氧基硅烷表面处理显著降低了温度老化条件下钻井引起的损伤，表明其在提高复合材料耐久性和可加工性方面的有效性。这些高度稳定的处理复合材料可用于汽车、航空航天和结构应用，在这些应用中，需要固定大的钻孔和紧固件来临时或永久地连接结构部件。

期刊介绍： The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science. The Journal of Rubber Research welcomes research on: the upstream, including crop management, crop improvement and protection, and biotechnology; the midstream, including processing and effluent management; the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory; economics, including the economics of rubber production, consumption, and market analysis. The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines. Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
