Enhancement of carbon fiber/epoxy composite electrical, optical and thermal properties by using different types of nano-additives

Abstract Environmental space threats are becoming more critical as they affect the optical, thermal, and electrical properties of reinforced fiber polymeric-based materials in spacecraft. Three different Nano-particles Alumina (Al 2 ,O 3 ), Multiwall Carbon Nanotubes (MWCNT), Reduced Graphene Oxide (RGO) were added to epoxy matrix then by bidirectional carbon plain form fiber/epoxy hand lay-up using autoclave curing technique make three materials. In this paper, electrical, thermal fiber/Epoxy Nanocomposite studied. Fourier transform infrared (FTIR) was performed evaluate structural changes newly synthesized The tested UV-visible Spectroscopy, Photo-acoustic spectroscopy (PA), Keithley 2635A respectively. results showed an enhancement after addition Nano-particles. optical test that neat epoxy/Nano-particles absorption spectra range. indicated parameters diffusivity, effusivity, conductivity best MWCNTs. pointed out Nano-particles, changed from insulating material a semi-conductive material.
