摘要/Abstract

摘要：

为减少涤纶用量以保护石油资源,制备了涤纶/苎麻混杂非织造复合材料。分析了涤纶/苎麻混杂量对非织造复合材料在管道翻衬施工及修复中拉伸强度的影响,利用复合材料混合定律和胡克定律建立了管道修复用涤纶/苎麻非织造材料内衬复合材料的理论临界混杂比和拉伸强度计算公式。结果表明:理论临界混杂比为0.177,实验所得临界混杂比在0.2附近,实验拉伸强度与理论拉伸强度的变化规律基本一致。临界混杂比和拉伸强度计算公式具有较高的实用性,可为翻衬修复受损大管径、非压力排污或排水管道的管状非织造复合材料的设计和生产加工提供参考。

Abstract:

In order to reduce the requirements of polyester resources hence the petroleum resources, polyester/ramie hybrid nonwoven composites were prepared. It was found that hybridizing polyester and ramie would have certain effect on the tensile strength of the pipeline after lining construction and repair. In this paper, the formulae for calculating the critical hybrid ratio and tensile strength of polyester/ramie nonwovens lining composites for pipeline repairing were established based on the law of mixing of composite materials and Hooke's law. The theoretical ratio was found to be 0.177 and the experimental ratio was around 0.2. The experimental tensile strength was basically consistent with the theoretical prediction. The results show that the formula for calculating critical hybrid ratio and tensile strength are practically useful, which can provide theoretical basis for the design and manufacture of tubular nonwovens composites for repairing damaged pipelines with pipes with large pipe diameters, such as non-pressure sewage and drainage.

Key words: pipeline rehabilitation, polyester/ramie nonwoven composite, hybrid theory, critical volume fraction, tensile strength
