Abstract

The statistical st rength and dist ribution of 5 cm PBO single fiber t reated with six different chemicalmediums were researched based on Weibull/ weakest-link model. The results were compared with the unt reated PBOfiber, and the surface of the fiber was analyzed by SEM. The results show that acidic mediums have more effects onthe strength and dist ribution of PBO fiber, and the break mechanisms are different between t reatment s by HCl andby H₂SO₄ .
