Abstract
A containment structure for a propulsion device, comprising a plurality of laminates arranged in a stack for absorbing projectile impact from the propulsion device, each laminate comprising a multi-ply composite of fibre reinforcement material and matrix material. The plurality of laminates comprises a plurality of primary laminates and a plurality of secondary laminates provided in an alternating arrangement along a stacking direction S of the containment structure. The primary laminates comprise a first fibre reinforcement material and the secondary laminates comprises a second fibre reinforcement material. The first fibre reinforcement material has a higher elongation to failure than the second fibre reinforcement material.
