Abstract: Aiming at inner wall prone collapse problems in the conventional pipe lining repair material construction, combined with the rapid development of current green fiber composite material, adding ramie yarn in polyester woven fabric lining material was advised, and polyester-ramie composite woven fabric was producted to improve pipeline rehabilitation lined woven fabrics resin impregnated performance, the bonding performance of inner lining materials and pipe wall was enhanced. The appearance of fiber and fracture surface after pulling experiment was observed by electron microscope. With the resin and fabric contact angle testing, bonding experiment, a comprehensive analysis of the resin penetration of polyester-ramie composite woven fabrics was made. Meanwhile, mechanical properties of polyester/ramie composite woven fabric were texted in order to meet the inner lining composite materials strength requirements. Experimental results show that the use of polyester/ramie woven composite manner as described above, can significantly improve the resin penetration, and it's beneficial for carrying more resin to improve bonding performance of resin and pipe wall, and can reduce the likelihood of collapse. While, the tensile and bursting performance of woven fabric added ramie composite can meet the repair requirements of high-pressure gas pipeline.
