A possible solution to address these issues is to use a coated textile composed of a single material. The highly oriented skin thickness is the most important factor in determining the tensile properties of the sample. A dwell time of 2 min was found to be optimum because this gave the required percentage of melted material to bind the structure together, while giving only a small decrease in molecular weight. The parametric studies are performed on the stress field along the elements of reinforcements, using image processing to correlate the influence of reinforcement architectures with the failure mechanism of WSPC.
