Abstract

Carbon Nanotubes (CNTs) have been a subject of interest for most of the researches after their discovery, due to their superior mechanical properties and ability to be used as the reinforcement phase in nanocomposites. The other carbon structure which was discovered a few years after the discovery of CNTs was Carbon Nanohorns (CNHs). The structure of CNH is cone-shaped compared to the cylindrical shape of CNTs structure. This cone-shaped structure causes difficulties in finding the stress distribution in CNHs when embedded in the matrix phase of nanocomposites. In this paper the governing differential equation of the stress distribution on the CNHs placed in a nanocomposite matrix is derived using some simplifying assumptions. It has been shown here that while the stress distribution is symmetric for the special case of CNT, it is non-symmetric for the general CNHs and the maximum stress shifts toward the tip of CNH.
