Multi-Criteria Evaluation of Advanced Polymer Composites Using TOPSIS Method: A Comparative Analysis of Material Performance

In this study, we analyze advanced polymer composites and classify these materials into five categories: metal composites, ceramic composites, wood-based composites, natural fiber composites, and concrete composites. The focus of this analysis is to study the performance of these composites based on the following four criteria: being lightweight, corrosion resistance, customizability of properties, and ease of manufacturing. Each of these criteria is assigned an equal weight of 0.25. The method used to conduct the evaluation is the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. In this method, the performance of each composite is normalized, the weights are applied, and preference values are calculated to obtain the

final rank. The results show that metal composites rank the highest, with a Ci value of 0.7632, with concrete composites, natural fiber composites, wood-based composites, and ceramic composites following. Concrete composites are also noted for being particularly lightweight, while ceramic composites are noted for exhibiting a high potential for customizability and metal composites are noted for exhibiting high corrosion resistance. This research shows that while no one composite material can be uniformly applied to all criteria, each composite material has enough unique strengths to be useful for a targeted application. This analysis also provides a basis for selecting the appropriate material for use in various engineering applications that require lightweight

construction, durability, and the ability to customize and manufacture the composite material.
