Development and mechanical characterization of a waste polyamide-reinforced polymer matrix composite

In this study, a novel, eco-friendly, and cost-effective polymer matrix composite was developed by incorporating waste polyamide yarns derived from industrial processes. The mechanical properties of this composite were comprehensively investigated. The primary objective of the research is to promote sustainability and cost efficiency through the utilization of waste materials while producing high-performance materials. To evaluate the mechanical performance of the resin composite, fundamental mechanical tests such as tensile testing, three-point bending tests, and delamination (interfacial) testing were conducted. These tests were performed to assess critical parameters including flexural strength, flexural modulus, strain at break, and stress performance. The study also examined the effects of polyamide yarns with varying dimensions on the composite material. The analyses revealed detailed insights into how experimental parameters influence the mechanical behavior of the material. The results demonstrated that the incorporation of waste polyamide significantly enhances the mechanical properties of the polymer matrix composite and that optimized formulations hold strong potential for industrial applications.
