Abstract
Thrust reverser composite cascade (1), comprising at least one longitudinal wall (15) and transverse walls (14) connecting to this longitudinal wall, characterized in that the longitudinal wall comprises at least one continuous longitudinal fibre bundle (19) and the transverse walls each comprise at least one continuous transverse fibre bundle (23) crossing the longitudinal bundle, so that the intersections (16) of the transverse and longitudinal walls are structurally bridged in both directions by the reinforcing continuous longitudinal and transverse fibre bundles.
Claims19
Thrust reverser composite cascade comprising cells, at least some of them having overhanging shapes, the cascade comprising:
- at least one longitudinal wall comprising at least one continuous longitudinal fibre bundle with a textile fibre reinforcement architecture,
- transverse walls connecting to this at least one longitudinal wall, the transverse walls each comprising at least one continuous transverse fibre bundle with a textile fibre reinforcement architecture crossing the longitudinal bundle, so that the intersections of the transverse and longitudinal walls are structurally bridged in both directions by the continuous longitudinal and transverse fibre bundles.
Process according to the preceding claim, the captive insert being removed from the cascade by chemical attack, mechanical fragmentation, deformation, melting and/or dissolution.
