Abstract:The laser-assisted fibre placement process (LAFP) is a key manufacturing technique used to fabricate thermoplastic composite components. It involves precise placement of reinforcing fibres onto a substrate using a laser to heat and consolidate the material. One of the critical factors affecting the quality of the process is the temperature at the nip point, where the substrate and tape come into contact. Temperature variations at the nip-point can lead to defects such as voids, delamination, or material degradation. Process models can improve the time-intensive trial-and-error approach currently used, provided that the physics are described accurately enough. Further, if the developed model is fast enough, it could be used to control the process in real-time. Therefore, in this research a numerical model of the LAFP process is developed, as a first step, to better understand the process parameter influences and its interdependencies. Usually, numerical models involving multiple domains of physics are computationally expensive and are not fast enough to make predictions of variation in quantities of interest in real time. Hence, as a second step, a surrogate model is created to reduce the prediction time, with the help of the data generated from the experimentally validated numerical model.
