AC and DC Cure Monitoring: An Overview
Sponsored by Lambient TechnologiesMay 28 2021 Both AC and DC techniques can be utilized to analyze thermoset and composite cure. AC dielectric cure monitoring, also known as Dielectric Analysis (DEA) agitates a sensor with a sinusoidal signal of a particular frequency and amplitude, applying a DC bias of zero volts. The measured frequency independent resistance, or ion viscosity, corresponds to the cure state of the Material Under Test (MUT). Similarly, DC resistance cure monitoring probes a material but alternatively uses a excitation voltage V DC that remains constant. AC and DC signals....
