Preparation and Properties of the Tubular Nonwoven Composite Material Applied on Pipeline Rehabilitation

摘要：

　　Based on requirement of intensity and thickness for the tubular nonwoven composite material by the big pipeline rehabilitation,the preparation and properties of the tubular nonwoven composite material were researched.To add fabric to reinforce the tubular nonwoven composite material; two pieces or more of the reinforced nonwoven were designed,so the structure of the tubular nonwoven composite material with the seams in circle direction equidistant,the structure of the tubular nonwoven composite material with many seams is symmetry,during inversion,the collecting of the stress of the single seam can be avoided,so the crazing of the seam is prevented; when the reinforced nonwoven is coverd film,at its two sides the areas for sewing were obligated,the difficulty of the sewing is decreased,the efficiency of the sewing is increased,and the thickness of the seam is decreased,the film jointing of the seam become more easy,the airproof of the tubular nonwoven composite material can be guaranteed.The test result shows that mechanical property,width and airproof property can meet the design requirement,and the corrosion resistance can meet the requirement of the standard.
