Overview: This paper aim at developing methodologies to design crashworthy composite commercial aircraft fuselages, a 2 frames section based on the A321 AIRBUS standard dimensions was manufactured by AIRBUS France, in order to be crash-tested at the Toulouse Aeronautical Test Centre. Though most p re-test numerical analyses confirmed this expected rupture behavior i.e. a crushing of the sinewave beams, the structure finally proved to fail in an unexpected manner since the crash test finally led to a rupture of the sub-cargo beams located above the absorbers.
