Abstract:In order to explore the influence of phenolic resin on the properties of aramid paper honeycomb, two different phenolic resins were used to prepare aramid paper honeycomb core materials, and the compression properties and shear properties of the prepared honeycomb core material were tested. Combining the observation of resin end face resin distribution and contact angle measurement, the reasons for the difference in performance of honeycomb core materials prepared by two kinds of resins were analyzed. The results show that the volatilization rate of solvent water in the resin and the surface tension between the resin and the aramid paper affect the resin distribution of the resin on the honeycomb wall,When the content of the honeycomb core resin is the same, the resin rubber column at the end of the joint is beneficial to increase the compressive strength of the honeycomb core material, but the accumulation of the resin at the end of the node reduces the wall thickness of the honeycomb, resulting in a decrease in the shear strength and modulus of the honeycomb.
