In this article, Lambient describes how it has achieved the cure monitoring of carbon fiber composites with dielectric sensors and the implications this has on large-scale production and manufacture.

In this article, Lambient Technologies discusses the major differences between AC and DC cure monitoring. They also help determine which measurements are better for different situations with respect to cure monitoring.

Dielectric cure monitoring (DEA) allows for the measurement of cure in real-time. This allows for detailed analysis of materials such as H.B. Fuller U3345, a UV-cured adhesive.

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....
