Abstract

This paper considers development and analysis of the mechanical behaviour of tubes which are made of composite materials under loading. Composite materials interface between layers have an essential influence on mechanical characteristics and are hardly predictable be-fore combining this mix. Presented analysis focuses on tubes, made of unidirectional carbon fiber, epoxy resin, considering various structure combinations and influence on mechanical behaviour under critical circumstances. The specimen tubes were reinforced using the polyacrylonitrile-based Toray T700 carbon fiber tow, of intermediate strength and modulus, combined with epoxy resin matrix of different impregnation, in order to analyse these variations effect on stiffness and bending strength characteristics.
