The Role of Reinforcement Matrix Interfaces in Advanced Composite Materials using Weighted Sum Method

Advanced composite materials have emerged as a transformative solution in modern engineering due to their superior mechanical properties achieved through the combination of matrices and reinforcements. The effectiveness of these composites largely depends on the reinforcement–matrix interface formed during manufacturing. Any incompatibility between the reinforcement and matrix materials may result in premature structural failure, emphasizing the importance of appropriate material selection and design optimization. Advanced composites are increasingly significant in aerospace applications because of their high strength-to-weight ratio, durability, thermal resistance, and fatigue performance. Consequently, the development of improved resins, enhanced bonding agents, and high-performance reinforcements has become essential for meeting future technological demands. This study evaluates different advanced composite materials, including Carbon Fiber Reinforced Polymer (CFRP), Glass Fiber Reinforced Polymer (GFRP), Aramid Fiber Reinforced Polymer (AFRP), Natural Fiber Reinforced Polymer (NFRP), and Basalt Fiber Reinforced Polymer (BFRP). The evaluation criteria considered tensile strength, thermal resistance, cost, and density using the weighted sum method. The results reveal that BFRP achieved the highest overall ranking because of its balanced mechanical and thermal properties, whereas GFRP obtained the lowest ranking among the evaluated composite materials.
