Fracture toughness remains low in Fiber Reinforced Plastics (FRP) composites compared to metals of equal strength due to a lack of plastic ductility. Metal wires such as 2000-4200 MPa (250-600 KSI) steel wires have good plastic ductility under tension, bending, and torsion. Current work uses a net structure of steel wires of 700 MPa (110 KSI). Multiple layers of net have been used to reinforce a polyester matrix. This paper will highlight the potential of this new composite.
