Abstract Scope |
The fabrication process of advanced composites is highly complex, with stringent requirements for manufacturing outcome, often outlined as process specifications. Studying the curing process through numerical simulations is crucial to enable process optimizing without solely relying on expensive and laborious experiments.
Multi-field simulation is a fundamental approach for evaluating the effects of process parameters on the final performance of composites. This study proposes a detailed analysis of the process in terms of temperature, degree of cure, and part deformation during processing. Using a coupled one-dimensional thermochemical model with the finite element method, it is possible to simultaneously predict the temperature and degree of cure trends during curing. At the same time, an advanced one-dimensional model derived in the framework of the Carrera Unified Formulation allows accurate evaluation of process-induced deformations and residual stresses.
This paper presents numerical results that highlight the effectiveness of the proposed approach in predicting the behavior of a simple composite part. Accurate prediction of the gradients across the part thickness during curing and the consequent changes in the material's properties is needed for process optimization and a realistic assessment of the part's final performance.
The results demonstrate the capability of the presented numerical tool to obtain a 3D digital representation of the cured part geometry and stresses. Results can be used to minimize curing time and mitigate processing-defects, thus increasing process efficiency and part quality. |
