Abstract [en]

The design freedom of composite parts is often limited by the material and/or manufacturing process. When approaching the limits of the processing window, manufacturing robustness is lost, and defects occur. Most common defects are out of plane laminate wrinkles, voids, porosities, delamination, thickness deviations and fibre angle misalignments. The process settings resulting in defects needs to be translated into hard limitations. The research community has during the years added excellent contributions to the understanding of defect generation. In this work we will present the engineering adoption of these results into industrial practice to further improve the composite manufacturing. This work is focusing on corner thickness deviations during manufacturing of carbon/epoxy parts out of Uni-Directional prepreg.
