Abstract
A structure such as a containment case (2) for a gas turbine engine (1) comprises an annular housing (3) made of composite material. A sleeve-like flange unit (4) is fitted onto an end of the housing (3) and is mechanically joined thereto by a first portion (31, 32, 33) of the composite material of the housing which projects into a recess (411) of the flange unit (4). This reduces or eliminates the need to use mechanical fasteners to connect the housing (3) to the flange unit (4).
