Influence of glass fiber on mechanical properties of UV-cured lining materials

Abstract Glass fiber is an important component of resin composites and greatly affects the properties materials. UV-cured pipe rehabilitation lining materials prepared by hand lay-up process using glass fibers with different areal densities weaving types were studied in this paper. Their thermal stability mechanical properties, such as flexural strength, modulus, tensile studied. The results show that fiber-reinforced material has good at 300°C. With density increase, material’s modulus increase. Compared plaid stitch-bonded felt lapped felt, higher degree bonding between warp-knitted can significantly improve strength material.
