	The development of nano-particle reinforced polymer composites is presently seen as one of the most promising approaches in the field of future engineering applications. The unique properties of at least some of these nano-particles (e.g., CNTs or carbon black) and the possibility of combining them with conventional reinforcements (e.g., carbon-, glass- or aramid-fibres), has led to an intense research in the field of nanocomposites. This study presents mechanical properties of two carbon composites made from bisphenol A epoxy resin (E) and 3 layers of 160 g/m 2 carbon cloth with twill (TC) and plain (PC) weave as a reference and three-composite system that consists from carbon fiber reinforced epoxy matrix and 1% of multi-wall carbon nanotubes dispersed in epoxy resin. Used hardener H507 was based on cycloaliphatic polyamine with absence of nonylphenol. Samples were also tempered at 80 ºC (for 12hours) for improvement of their thermal resistance. Mutual comparison of obtained tensile strength values are shown on Fig. 2. As it is shown, the presence of carbon nanotubes in carbon cloth/epoxy system improves its strength, but exposure to elevated temperatures lowers the tensile strength of samples. Also difference in strength between twill and plain weave of carbon cloth were observed.
