<p>The panel has a rigid support (52) fixed on an inner wall of a fan casing (20). The case has a side covered of a stratified structure (50) carrying a layer of abradable material (42). The structure has fiber sheets drowned in an epoxy resin. The structure has an upstream part (54) covered by the abradable material and a downstream part (56) that extends above the abradable material. The part (56) has thickness greater than thickness of the upstream part, and resists impacts of ice. Cells are closed by polymer foam (58) and the support is an alveolar structure.</p> |
