Abstract: In this paper, investigation results of tensile testing of specific jointed assembly of two elements, realized by pins, are presented. One element is specific composite tube, produced by filament winding technology using glass fiber impregnated with polyester resin, and another element is cylindrical steel part, obtained by standard machining technology. An assembly specific composite part/metallic part, jointed by pins, was exposed to the action of axial tensile stress. A tensile breaking force of mentioned assembly is determined. An influence of pins number to tensile breaking force of mentioned joint is presented. A failure mechanism of specific composite tubes is described.

Keywords: Polymeric composites, filament winding technology, tubes, joining, pins, tensile characteristics.
