Popis: This paper presents the properties of epoxy nanocomposites, prepared using a synthesized hybrid carbon nanotube–alumina (CNT–Al 2 O 3 ) filler, via chemical vapour deposition and a physically mixed CNT–Al 2 O 3 filler, at various filler loadings (i.e., 1–5%). The tensile and thermal properties of both nanocomposites were investigated at different weight percentages of filler loading. The CNT–Al 2 O 3 hybrid epoxy composites showed higher tensile and thermal properties than the CNT–Al 2 O 3 physically mixed epoxy composites. This increase was associated with the homogenous dispersion of CNT–Al 2 O 3 particle filler; as observed under a field emission scanning electron microscope. It was demonstrated that the CNT–Al 2 O 3 hybrid epoxy composites are capable of increasing tensile strength by up to 30%, giving a tensile modulus of 39%, thermal conductivity of 20%, and a glass transition temperature value of 25%, when compared to a neat epoxy composite.
