Influence of fiber orientation on the behavior of composite pipes subject to internal pressures

Abstract

In the field of engineering the matrices reinforced by synthetic fibers have become widely used in view of the high specific stiffness and resistance they offer. The main objective of this work is to simulate and analyze the mechanical behavior of a multilayer composite pipe for different fiber orientation angle. A finite element numerical model (MEF) under ANSYS has been developed to determine the displacement fields for a multilayer pipe under internal pressure. Subsequently, a parametric study was carried out to enhance the effect of the mechanical and geometrical characteristics of the materials constituting the multi-layer pipe. From the results obtained, it was found that the displacement fields are clearly influenced by the orientations of the composite layers.
