| Abstract: | In this paper,the methods of chemical etching combining with swelling and argon plasma with chemical coupling were employed to modify the surface of PBO fibers.Furthermore,the influences of the treating conditions on the surface properties of PBO fibers were studied,and the fiber surface chemical structure and morphologies were characterized by the means of EM and SEM as well.A single fiber pullout test was chosen to measure the interfacial shearing strength(IFSS) between the fiber and the epoxy resin.From the results,it can be shown that the argon plasma combining with chemical coupling is the further optimal method to improve the interfacial adhesion between the fiber and the matrix. |
