Cure Monitoring cf Thermosetting Composites by Lacomtech Dielectrometry

摘要

The properties of thermosetting resins are dependent on the degree of cure and consolidation quality. Since the consolidation process of thermosetting resin matrix fiber composites is much dependent on the viscosity of resin in the composites, in this study, the dissipation factor which is a function of viscosity was measured by the newly developed Lacomtech dielectrometry apparatus and sensors. Using the measured dissipation factors, and the relationship between the dissipation factor and degree of cure with respect to environmental temperature was investigated.
