Strengthening fibers and layers in nanocomposites can make these materials suitable for many applications such as automobile, sport goods, aerospace, etc. Currently, scientists are still looking for materials with higher strength, but still lightweight because of consuming less fuel and energy in industries such as automobile and aerospace. In this research, by considering thermal fatigue resistance management technology between the nanofibers and layers, it was attempted to achieve a new super reinforced MWCNT/epoxy. This nanocomposite consists of MWCNTs with 25 nm diameter, triple-walled CNTs and single layer graphene. The reinforcing theory, which is suggested in this study, is to cover the triple-walled CNT with MWCNT with 25 nm diameter. Furthermore, all of the empty space between interior of triple-walled CNT and MWCNT should be filled out with rolled graphene layers. The recommended super reinforced MWCNT/epoxy offers a very high strength, but still is lightweight. Furthermore, the recommended nanocomposite has a high thermal fatigue resistance.
Key words: Super reinforced nanocomposite, thermal fatigue resistance, coefficient of thermal expansion, Nano-fibers, single layer grapheme, MWCNT.
