Abstract: "Thermoplastic composites are gaining attention in aerospace, automotive, and energy sectors due to their advantages, including potential for rapid manufacturing, automation, adoption of conventional metal processing techniques, repairability, recyclability, and higher shelf life. Utilization of thermoplastic composites has potential challenges such as higher processing temperatures, higher matrix viscosity, and the possibility for process-induced defects such as non-uniform heating and cooling, lack of consolidation, residual stresses, delamination, and wrinkles. Process simulation has emerged as a crucial tool for understanding the effect of process parameters on the final product state, thereby minimizing manufacturing risks and costs. The precision and effectiveness of process simulation relies on material models that accurately represent the evolution of material state during processing. These material models are mathematical representations of various phenomena of interest. This paper presents an overview of characterization of Toray Cetex® TC1225 T1100G thermoplastic composite for process simulation. The characterization includes crystallization and melt kinetics and modulus development and relaxation. The study employs the COMPRO and RAVEN process simulation platforms from Convergent to predict melt and crystallization and modulus development. The model predictions are compared with experimental measurements, offering valuable insights into optimizing thermoplastic composite manufacturing processes."
