Abstract

In the present work a novel technique was used to fabricate multiwalled carbon nanotubes (MWCNT) impregnated Epoxy composites. In the context of high strength and superior thermal properties of carbon nanotubes infused epoxy composites, our emphasis is to evaluate the effect of post curing temperature on these composites by different thermo mechanical analysis such as DMA, TMA, and TGA tests. Tests were conducted for two different sets of nanocomposites processed by two different post curing temperatures. For each post curing temperature, samples with different weight percentages of MWCNT were tested. Also, Flexure tests were performed in order to evaluate the mechanical properties of these composites. Fracture surfaces of the test specimens were observed by SEM in order to verify the dispersion, and the effect of addition of nanotubes in matrix epoxy. It was found that with the increase of the percentage of carbon nanotubes (CNT) the storage modulus and the glass transition temperature (T g) of the nanocomposites increase. However, the TGA results indicated that the addition of nanotubes did not show any significant difference in decomposition temperature in comparison to neat epoxy.
