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