Cure, Shrinkage and Properties of an Epoxy Material
O Sindt, S L. Simon, G B. McKenna, E Liang
This work focuses on obtaining data to perform realistic finite element models of residual stresses in composite parts made of toughened epoxy thermosets. The initial thrust of the work is aimed at studying the volumetric behavior before, during, and after cure. The cure kinetics were also examined in order to relate the volume shrinkage during cure to changes in conversion. In this paper, the DSC cure kinetic studies will first be summarized, followed by the dilatometric measurements.
