摘要
A method for making a honeycomb composite structure wherein the method allows for fluid flow from cells of a honeycomb core during a cure process. More specifically, the method involves forming one or more vents in a skin of the structure, which are preferably filled with venting wicks, to allow for fluid flow before being sealed by the polymer matrix during a skin bonding process. Additionally, the structure preferably comprises a scrim that allows for fluid flow between multiple cells of the honeycomb core. The honeycomb composite structure produced according to this process comprises, among other things, a sealed venting region that comprises a polymer matrix and fibers that are transverse to the skin.
