Abstract
In this paper, we added the carbon fiber into the aramid pulp and then prepared the dielectric loss aramid paper, which was used to prepare honeycomb-core materials. We also prepared different specifications microwave absorbing honeycomb with dielectric loss aramid paper as raw material, and investigated the relationship between honeycomb nonsteady compressive strength, horizontal shear strength, longitudinal shear strength and phenolic resin increment. The microwave absorbing property was also characterized. The results showed that, the addition of carbon fiber as absorber into the normal aramid paper could bring good microwave absorbing property for the honeycomb, and also less impact on mechanical properties. The microwave absorbing honeycomb based dielectric loss aramid paper had good nonsteady compressive strength and shear strength, especially the shear modulus. Importantly, the microwave absorbing honeycomb based dielectric loss aramid paper exhibits excellent microwave absorbing ability, and it will be a new type of application prospect in aerospace field.
