Carbon Nanotube Enhanced Composite Materials

چکیده
Non covalent functionalization by π stacking was accomplished by treating multi walled carbon nanotubes (MWNTs) through the use of Kentera, a conjugate rigid rod polymer. The functionalized MWNTs were then introduced into the epoxy resins through a combination of shear and elongation forces. The resulting epoxy resin (containing MWNTs) was then impregnated with carbon fiber under hot-melt conditions to produce epoxy pre-preg. Composites were fabricated from both epoxy resin and prepreg by hand lay ups and cured in autoclave. Mechanical testing showed about 50% and 25% improvements in flexural strength and modulus respectively. Furthermore, SEM, DMA, and mechanical test data of the composites suggested formation of strong interfacial bonding between the MWNTs, epoxy matrix and carbon fiber.
