Abstract
Advanced Fibre-reinforced composites, renowned for their remarkable mechanical properties including high strength, stiffness, and fatigue resistance, have garnered considerable attention. To elevate these materials’ performance and meet the escalating demands of modern applications, researchers have delved into hybridization strategies. Hybridization entails amalgamating diverse Fibres, encompassing carbon, glass, aramid, and natural Fibres, within a single composite matrix to engender synergistic effects and attain superior mechanical performance. This study employs the COPRAS (Complex Proportional Assessment) multi-criteria decision-making method to comprehensively assess the mechanical properties and manufacturing intricacies of various carbon Fibre hybrid composites. Parameters such as tensile strength, flexural strength, impact strength, compressive strength, density, cost, and manufacturing complexity are meticulously scrutinized. Findings reveal that integrating alternative Fibres, particularly natural variants like kenaf and bamboo, markedly enhances the mechanical attributes of carbon Fibre-based composites. Nonetheless, this enhancement is accompanied by escalated manufacturing intricacies and costs. The COPRAS method furnishes a systematic framework for prioritizing hybrid composites based on their significance, utility, and the delicate balance between benefits and costs. Insights gleaned from this study can aid decision-makers in aligning material selection with specific application requisites and financial constraints, ultimately fostering the development of advanced, cost-effective, and sustainable composite solutions. Integrating the COPRAS approach with emerging technologies such as artificial intelligence and automated manufacturing holds promise for further augmenting the optimization and adoption of high-performance Fibre-reinforced composites.
