Abstract

The aim of this study is to investigate the mechanical properties of continuous glass fi ber reinforced composite tubes produced by fi lament winding technique with three different winding angles. With help of split-disk tests hoop tensile properties of selected specimens were determined, where reliable results were obtained with low standard deviations. It was observed that bigger winding angle lead to higher hoop tensile properties of fi lament wound tubular samples. Also, the effect of reinforcement direction on the mechanical performances of these composites has been presented. Fiber fracture and fi ber-matrix debonding is observed to be the dominant failure mechanisms by samples winded with bigger winding angles, whereas delamination in addition to these mechanisms is detected by samples with smaller winding angles. From received results it is concluded that, mechanical properties of composite specimens are depended from winding angles in fi lament winding technology. With help of conducted SEM analysis good merger between glass fi bers and the epoxy matrix was seen, but cracks within plies and broken fi ber were noticed, due to the high fi ber branching.
