- Abstract
The application of polyimide(PI) fibers in the field of composite materials has been limited because of their smooth surface and chemical inertness. In order to overcome these problems, oxygen plasma was used to modify the surface of fibers. The single fiber fragmentation test (SFFT) was used to characterize the interfacial adhesion performance of PI fiber as a simple and accurate analysis method. It was found that the interfacial shear strength between the fiber and resin after oxygen plasma modification was increased by 54% compared to the untreated fiber. Meanwhile, the surface micromorphology, chemical composition, wettability of fibers and the interface morphology at the fiber fracture were analyzed by field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS), contact angle measurement and polarizing microscope, respectively. All of these results demonstrated that the single fiber fragmentation test for analyzing the interfacial adhesion of PI fibers was effective.
