Fire protection of a fan casing made of composite
First Claim
1. A fire protection methodthe fire protection method comprising the following successive steps:
- providing a fan casing comprising an overall cylindrical barrel having a main direction extending along a longitudinal axis and an upstream flange radially extending relative to the longitudinal axis from an upstream end of the barrel, the fan casing being made of composite material comprising a fiber reinforcement densified by a matrix, said matrix having been polymerized,draping, on an upstream radial face of the upstream flange of the fan casing, panels comprising prepreg glass fibers with a resin capable of thermally protecting the fan casing against fire, the resin of the panels being unpolymerized during the draping step, andpolymerizing the resin of the panels to obtain a protective layer.

Abstract
Method (S) for protecting against fire a fan casing (1) comprising a roughly cylindrical barrel (10) having a main direction extending along a longitudinal axis (X) and an upstream flange (20) extending radially with respect to the longitudinal axis (X) from an upstream end of the barrel (10), the fan casing (1) being made of a composite comprising a fibrous reinforcement densified by a matrix, said matrix being polymerized, the protection method(S) comprising the following steps:⋅—laying (SI) widths containing glass fibre pre-impregnated with a resin capable of affording the fan casing with thermal protection against fire on an upstream radial face (22) of the upstream flange (20), and ⋅—polymerizing (S2) the resin in order to obtain a protective layer (2).
