A Loop Test to Evaluate Strength of Glass Fiber and Comparison with Tensile Test

摘要

There are two types of tests, tensile test and loop test, to measure the strength of fibers (monofilaments), which are commonly used for fiber-reinforced plastics (FRPs). Owing to a difference of gage lengths, we had difficulty comparing both results by means of these tests. In this paper, we tried to make a comparison between strengths in terms of the same gage lengths, which were converted by Modified Weibull theory. Also, we conducted a simulation for the loop test.
