Abstract

The phenomenon of core crush encountered in the aerospace industry during manufacture of co-cured composite panels has been explained. An experimental program which relied on direct measurement of pressure within the honeycomb core using an optical sensing technique has been used in conjunction with experimental observation and numerical modeling to determine the sequence of events which lead to this costly problem. Having understood the issue, it is now possible to take steps to reduce or eliminate the occurrence of core crush.
