Abstract

Radiation can be used to modify and improve the properties of materials. Electron beam irradiation has potential application in modifying the structure of carbon fibers and carbon nanofibers in order to produce useful defects in the graphite structure and create reactive sites. In this project, a methodology will be developed to graft functional groups from acrylic acid on to carbon nanofiber surface leading to better dispersion and better matrix/fiber interface on composite manufacture. The grafted samples will be characterized through several techniques to evaluate the grafting process. Advanced composites will be produced for application in aerospace and defense industry. (AU)
