  Abstract

Tee-joints are the weakest links in the composite pipelines under internal pressure. In this paper, the internal pressure behavior of Tee-joint composites reinforced with integrated weft-knitted preforms was studied. For this purpose, a multiscale approach was developed on meso-and macro-scales using the homogenized fi nite element method and ABAQUS Commercial package. Three repetitive unit cells (RUC) of the weft-knitted composite were investigated on the mesoscale. Using the result of the mesoscale simulation, the internal pressure behavior of integrated and non-integrated Tee-joint composites was simulated on the macroscale. A burst pressure test was carried out on the prepared samples. The numerical and experimental results showed that the integrated Tee-shape preforms improve the internal pressure resistance of the Tee-joint composite so that the resistance against internal pressure of integrated Tee-joint composites is at least 40% higher than non-integrated Tee-joints.
