THE EFFECT OF CURING SCHEDULE ON THERMAL AND MECHANICAL PROPERTIES OF A VARTM PROCESSABLE EPOXY RESIN

摘要

For the VARTM resin investigated, all cure paths are not created equal. In a composite manufacturing environment it is important to use one cure schedule to produce parts with similar properties. For this presentation, the industrial resin will be compared to a model DGEBA and PACM epoxy system to better understand the behavior of complex VARTM formulations. We will demonstrate the insensitivity of the model system T_g to cure schedule and the influence of the aging endotherm on final resin fracture properties.
