Ansys Composite Cure Simulation
Evaluation of autoclave curing effects on composite laminates using the simulation
Deformations induced by the curing process (Process Induced Distortions - PID) are one of the main problems for composite materials production with polymer matrix (Fiber Reinforced Plastics - FRP). These effects are mainly caused by residual stresses that arise during the matrix polymerization. Process optimization can be pursued through a traditional trial & error approach, generally convenient and effective only for simple geometries. More complex composite parts require more sophisticated models which must be based on an in-depth understanding of residual stresses (e.g. different composite thermal expansion in-plane and through-the-thickness, shrinkage by polymerization, layup asymmetry, mold-composite interactions, etc.).
Ansys Composite Cure Simulation (ACCS) is a dedicated simulation technology to study the effects of the cure process for polymeric matrix composites. ACCS is implemented within the Workbench platform through ACT and it extends the thermal and structural solver capabilities. The integration in Workbench and Mechanical allows to exploit Ansys Composite PrepPost (ACP) for the composite lay-up definition. Through ACCS it's possible to optimize a pre-existing project reducing scraps and rework, it makes new products design cycle more efficient and optimizes mold geometry to reduce the onset of residual stress.
