SIMULATING PID FOR CURING IN A DIAPHRAGM FORMING STATION

Research output: Chapter in Book/Report/Conference proceedingsConference contributionpeer-review

Abstract

We describe the material characterization required to model curing and the resulting process induced deformations for a low temperature epoxy UD prepreg. This includes the cure kinetics, cure shrinkage, coefficient of thermal expansion and modulus-development. Material data was fit to models with python scripts. Curing experiments with multiple lay-ups were performed in a diaphragm forming station on aluminum tool equipped with heating cartiges. The process was modeled in Abaqus with the Compro plug-in. High-resolution 3D laser scans of manufactured parts were compared with the predicted process induced deformations and good agreement was observed.
