Anti-crash composite structure for aerocraft with controlled warping

The composite structure consists of transverse (18B) and lengthwise (18) walls, each comprising two layers (19) of composition material and an intermediate layer (20), with at least one of the outer layers having a corrugated inner core. The core's corrugations extend parallel to the outer laye...

Zusammenfassung:	The composite structure consists of transverse (18B) and lengthwise (18) walls, each comprising two layers (19) of composition material and an intermediate layer (20), with at least one of the outer layers having a corrugated inner core. The core's corrugations extend parallel to the outer layers for enhanced impact energy absorption capacity, and at least one of the outer layers has a weakened area (45) that leads to a controlled degradation of the layer in the event of an impact.
