摘要

The operational lifespan of woven composite structures involves experiencing a wide range of quasi-static and dynamic impact loads, which can result in different levels of damage, whether visible or nearly imperceptible. It is crucial to thoroughly analyze the response of composites to various types of loads, including low-strain and dynamic loads, both in-plane and out-of-plane. This study systematically evaluates the mechanical properties of glass, jute, and flax woven fabric-reinforced composites in both thermoplastic and thermoset matrices. The research addresses the growing interest in composite materials for their versatile and environmentally friendly characteristics. This investigation examines the impact of natural fibers (jute and flax) in combination with glass fibers, as well as the influence of matrix materials (thermoplastic and thermoset), on the mechanical behavior of advanced composites. The development of hybrid yarns, known as co-wrapped yarns (CWYs), involved the process of wrapping polypropylene (PP) filament around glass, jute, and flax rovings. Due to shortened impregnation periods and resin flow distances during processing, these CWYs have the potential for cost-effective manufacture of complex-shaped composite parts. The primary aim was to examine how reinforcement materials affect the mechanical performance of both thermoplastic and thermoset woven composites. A comprehensive suite of mechanical tests, including tensile, flexural, and impact assessments was conducted to evaluate critical properties such as strength, stiffness, toughness, and durability. The results revealed that under quasi-static loads such as tensile and flexural tests thermoset woven composites exhibited outstanding load-bearing performance, while thermoplastic composites showed exceptional resistance to dynamic impact forces. This research contributes to a deeper understanding of how different fiber types and matrix materials interact to influence mechanical properties, aiding in material selection and optimization for diverse engineering applications with a focus on sustainability.
