摘要

This study investigates the cooling phase in autoclave processing for composite materials, focusing on its impact on thermal properties. A three-dimensional numerical model was developed using Computational Fluid Dynamics (CFD) and validated with experimental data under controlled cooling conditions. The model accurately replicated the thermal dynamics, including heat transfer rates, convection effects and temperature changes along the composite. Numerical results showed that cooling is more uniform in horizontal direction due to material anisotropy. These findings underline the importance of controlling cooling parameters to minimize residual stresses and ensure optimal curing of composites. These findings provide a basis for optimizing autoclave processes in industries requiring high-performance composites.
