Abstract

Aramid/epoxy composites process excellent dielectric properties and that can be greatly influenced by thermal fields. In this paper, the rectangular waveguide testing system was modified and equipped with heating, temperature control and heat dissipation units. The accuracy of the testing system was verified by the dielectric properties of reference materials. Then the properties of unidirectional aramid/epoxy composites were measured in X-band from room temperature to 200℃. It can be founded that both the dielectric constants linear increase as temperature increase while the loss tangents are non-linear changed.
