Abstract
The continuous growth of the composites industry accompanied by the use of emerging new materials and more complex shapes and structures cause increasing difficulties in design, production and maintenance of composite products. One issue is the insufficient knowledge about the cure kinetics of the composites during production, which directly results in some badly cured composite parts. In this paper, the current progress of a dielectric sensor system for the in situ on-line cure monitoring of a composite material is presented. An interdigital sensor was fabricated by Flexible Circuit Board (FCB) technology. Dielectric properties of the resin, monitored by the interdigital sensor, changed over time during the curing. By analyzing the dielectric properties (relative permittivity, and loss factor), the degree of cure can be understood. The data obtained in the experiments clearly showed the different stages of the cure, which can be used with confidence for in situ and on-line monitoring of composites cure.
