摘要: 为研究FRP耐久性提出同体试验测试方法,以弹性模量为耐久性评价指标,开展了同体试验与破坏性试验两种方法的测试和分析,论述了FRP性能测试结果的影响因素。完成了湿热老化环境下20个同体试验试件与21个破坏性试验试件在不同老化时间点的弹性模量测试,通过试验数据验证分析了同体试验与破坏性试验的弹性模量有显著的正相关性,这种相关性可以把破坏性试验数据转换为同体试验数据并找到同一基准。其他不同制备工艺和不同试验工况下的FRP的同体试验与破坏性试验数据也存在类似的关系,FRP的耐久性具有相同的基准,以弹性模量来评价FRP耐久性的方法更加合理与科学。

Abstract: In order to study the durability of FRP, the non-failure test method is presented. The modulus of elasticity was used as the durability evaluation index, and two methods of the non-failure test and the failure test were tested and analyzed. The factors influencing FRP performance test results were discussed. Elastic modulus tests of 20 non-failure test specimens and 21 failure test specimens at different aging times were completed. The experimental data indicate that there is a significant positive correlation between the elastic modulus of the non-failure test and the failure test. This correlation can convert the failure test data into the data of the non-failure test and find the same benchmark. Similar relationship exists between the non-failure test and the failure test data under different preparation processes and different test conditions. The durability of FRP has the same benchmark, and it is more reasonable and scientific to evaluate the durability of FRP by elastic modulus.

Key words: durability, the non-failure test, the failure test, elastic modulus
