Method for fixing structural metal reinforcement on e.g. leading edge of fan blade, of aeronautical engine, involves heating compaction block so as to cause reticulation of adhesive and concomitant thermal expansion of block

摘要

The method involves pre-assembling a structural metal reinforcement (10) on a part of fan blade (1) with interposition of adhesive layer (20) between contact surfaces of the reinforcement and the part. The reinforcement is placed on the blade in a bonding mold (30) that has a carcass (31) and a compaction block (32) in contact with outer surface of the reinforcement, where the block is formed from a material whose thermal expansion coefficient is greater than that of carcass material. The block is heated to cause a reticulation of adhesive and concomitant thermal expansion of the block. An independent claim is also included for a bonding mold for implementing a method for fixing a structural metal reinforcement on a part of a blade.
