<P>PROBLEM TO BE SOLVED: To provide a composite blade resistant to impact from a foreign body without degrading a set of composite blades to reduce such a fault. <P>SOLUTION: This turbomachine blade comprises an aerodynamic surface made of a composite material and extending in a first direction 14 between a leading edge 16 and a trailing edge 18 and in a second direction between a root and a tip of the blade. The blade includes a solid metal reinforcement 32 adhesively bonded to the leading edge 16 of its aerodynamic surface, and the reinforcement extends along the first direction 14 beyond the leading edge of the aerodynamic surface and along the second direction between the root and the tip, and includes at least one recess 34a for absorbing at least a portion of the energy that results from the impact of the foreign body against the leading edge of the blade. <P>COPYRIGHT: (C)2008,JPO&INPIT |
