摘要
FRP作为一种复合材料,浸渍树脂是其重要的组成部分,因此,树脂本身的耐久性能对FRP材料的抗老化性能会有影响。对土木工程加固常用的树脂耐久性进行了试验研究,并对一部分试件进行了遮挡防护。考察华北地区自然环境条件对其抗拉强度、伸长率和弹性模量等的影响。2年已完成了7组共35个试件的试验。结果表明,有防护试件的性能优于无防护试件的性能。
As a complex material, infused resin is an important part of FRP. So durability of resin may have some influence on aging resistant capability of FRP. Tests and study were done on durability of resin common used in civil engineering, and some sheets were preserved. Influence of nature environment in north China to strength, extensibility and Young＇s modulus was investigated. Seven groups of sheets which are thirty-five sheets were tested in two years. The results indicates that property of sheets protected was better than the one unprotected.
