【摘要】 预应力混凝土可以改善使用阶段的各项性能,提高构件承载力,但碳纤维织物施加预应力,施工有一定困难,自应力混凝土无需张拉设备、工序简单,可张拉任何方向的纤维,造成多向应力,对于生产预应力碳纤维织物薄板来说,是一种很好的方法。为研究自应力碳纤维织物薄板性能,进行了张拉、弯曲、黏接以及耐腐蚀试验。试验结构表明:自应力混凝土可以提高构件的承载力,单层纤维网混凝土的耐腐蚀性有待提高,而双层纤维网混凝土的耐腐蚀性能良好。更多还原

【Abstract】 Prestress concrete can improve performance and improve load capacity at the use of stage.However,imposition of prestress carbon fiber fabric,the construction must have difficult,self-stressing concrete without tensioning equipment,easy process can be tensioned in any direc- tion of the fibers,causing many to stress,for the production of prestressed carbon fiber fabric sheet is a very best method.To study the self-stress of carbon fiber fabric sheet performance,conducted Tension,bending,bonding,and corrosion-resistant test.Test structures show that:self-stressing concrete can improve the bearing capacity of components,single-fiber network to be of concrete improve corrosion resistance,and double-fiber concrete Net good corrosion resistance.更多还原
