Bundle strength statistics of basalt fiber with Weibull model and G auss model

The applicability of Weibull distribution model and Gauss distribution model was confirmed by hypothesis testing in the bundle strength statistics of basal fibers. The bundle st rength dist ributions in different lengths of basalt fiber BF-CSH-01 , BF-CMD-02 and BF-CAH-01 were analyzed with both the models. When the fiber and sample length change , the bundle strength transformation trends are the same in the two models. Among the three kinds of basalt fibers , the fiber BF-CSH-01 has the highest bundle strength and the fiber BF-CMD-02 has the smallest variation coefficient . For the same basalt fiber , when the sample length increases , the bundle strengths and the variation coefficient s of the strength decrease. A comparison between the Weibull model and Gauss model shows that the former has the higher bundle strength and a bigger variation coefficient .
