Influence of fiber type and the layer thickness on the stress distribution in composite pipe

In this work authors presented distribution of circumferential stress in wound composite structures made from different layers. The cylindrical shape specimens were made from layers which have different elastic moduli. Manufactured specimens underwent strength test to obtain distribution of circumferential stress as a function of radius. Circumferential strain on outside surface was measured by fiber optic strain gauge. In order to verify the experimental results were made microscopy specimens, obtained material properties by homogenization method and calculated the strain using analytical approach. In the end, authors compared results obtained from both methods.
