FRP DURABILITY EVALUATION METHOD BASED ON ELASTIC MODULUS

Abstract

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
