Some Approaches for Evaluation of Impact Energy Absorption\ud in Composites for Civil Aircraft Applications

This project document gives the road map for the development of impact energy absorbing structures for use in civil aircraft applications. The chosen area of work has been-the seat system which has to be designed for vertical impacts with crash speeds upto 9.4 m/s. Filament wound braided tubes were thought of as replacement materials. Initial tests with filament wound tubes has shown promising applications
