Novel Experimental Approach to Enhancing the Tensile Properties of GFRP Laminates through Steel Wire Reinforcement

The limitations of traditional composite laminates in bearing complex and diverse loads have led researchers to explore innovative reinforcement methods. One such approach is the reinforcement of composite laminates using metallic wires. Due to their low cost and excellent mechanical properties, stainless steel wires are among the most suitable materials for reinforcing composite laminates. In this study, the effect of steel wire reinforcement on the tensile properties of Glass Fiber Reinforced Polymer (GFRP) laminates is investigated. Specimens with ۱, ۲, ۳, and ۴ longitudinal wires embedded in glass fiber laminates and fabricated using the vacuum bagging technique and subjected to tensile loading. The results demonstrated that wire reinforcement significantly enhances the tensile behavior of the laminates. Specifically, specimens with four wires exhibited a ۳۲-fold increase in absorbed energy, a ۵.۳-fold increase in tensile modulus, and a ۲۴-fold increase in specific energy absorption (SEA) compared to non-reinforced samples. Additionally, the use of wires substantially increased the ultimate displacement of the specimens. The findings of this study offer a novel solution, assisting researchers in optimizing the design and fabrication of wire-reinforced composites for various applications, enabling the production of lighter, stronger, and more durable components.
