Abstract:

Oxidized poly(acrylonitrile) fibers (OPF) upon thermal treatment of poly(acrylonitrile) has been achieved and has been used as raw material to produce carbon fibers. The influence of fibers on the mechanical properties of the composite of polymer matrix reinforced by fabric were analyzed in this study by using three types of advanced fibers. For this purpose, 13 composites of epoxy matrix reinforced by fabrics of carbon fiber, Kevlar and Glass fiber with OPF were prepared by manual padding of 4 layers with different arrangements. For the preparation of composite epoxy resin Bisphenol F and polyamine as a hardener were used with resin to fiber ratio of 60:40. The tensile properties and the fractured surface of the composite samples were studied. Results of the study showed that by increasing the ratio of OPF to carbon, to Kevlar and to Glass fabric, the tensile strength decreases but for the samples in which OPF is more than 50% the fracture strain is increased. The results of cross-sectional fracture showed that composite made with a carbon fiber fabric, Kevlar and Glass fabric with OPF have lateral, explosive and edge delamination failure mode occurs on the other hand by increasing the OPF content to composite transverse failure mode happens.
