AbstractThis paper focuses on the manufacturing of thermoplastic composite PEEK parts using Automated Tape Placement (ATP) with in-situ consolidation. The choice of the adequate processing parameters for the in-situ ATP is critical because no additional autoclave step is used to correct any manufacturing imperfections created during layup, or to homogenize the laminate consolidation. The current paper can be considered as a first step towards understanding the deformation behaviour of APC-2/IM7 (Cytec) in-situ ATP tape material subjected to various processing conditions. Compression analyses performed using a Dynamic Mechanical Analyzer (DMA) show that the material can quickly reach a steady state transverse deformation. The deformation behaviour of the pre-impregnated carbon/PEEK tape was investigated using a specially developed compaction apparatus. Processing parameters such as temperature, consolidation forces, and orientation of the deposited tow were independently controlled and the material's steady state deformation was measured by optical microscopy. The processing temperature was found to have negligible impact within the studied range. The consolidation pressure and ply orientation were found to contribute with similar magnitude to the tow deformation.
