Abstract
This comprehensive study evaluates polymer composites through a systematic analysis of their mechanical, thermal, chemical, and environmental properties using the Weighted Sum Method (WSM). The research explores five distinct composite This encompasses metal matrix composites (MMCs), ceramic matrix composites (CMCs), along with various other composite types. made with natural fibers, and Carbon Fiber Reinforced materials. Composites. Materials. Plastics (CFRP), and an additional variant of Natural Fiber Composites. The investigation reveals a nuanced landscape of material performance, demonstrating that no single composite material universally excels across all properties. Natural Fiber Composites emerged as the top-performing material, achieving the highest overall score (Qj = 1), primarily due to their balanced properties and environmental compatibility. Metal Matrix Composites secured second place with a robust Qj value of 0.8004, distinguished by exceptional mechanical properties and high thermal conductivity. Key findings highlight the critical importance of context-specific material selection. Each composite type presents unique advantages: Natural Fiber Composites offer sustainability, MMCs provide superior mechanical strength, Ceramic Matrix Composites demonstrate thermal stability, and Carbon Fiber Reinforced Plastics exhibit remarkable strength-to-weight ratios. The research underscores several significant insights: - Material selection must be tailored to specific application requirements - Sustainable materials are increasingly competitive - Composite materials offer diverse engineering possibilities Recommendations for future research include: - Enhancing bio-based composite performance - Developing hybrid composite materials - Exploring innovative manufacturing techniques - Improving environmental sustainability of composites This research advances the field of materials science. providing a comprehensive framework for evaluating polymer composites. It emphasizes the potential for advanced engineering solutions through precise material design and selection, ultimately supporting technological innovation and sustainable development.
