Crash-energy absorbing structure and method of fabrication.

The primary design goal crashworthiness in aerospace and automotive vehicles is to minimise the impact forces transmitted to the occupants during the crash events. In this study, an innovative lightweight composite energy-absorbing keel beam system has been developed to retrofit in aircraft and heli...
