Abstract:
1. A method of assembling a structure, comprising the steps of: providing a mould comprising a main body containing a thermally-expandable unit arranged to function as a movable portion, wherein the thermally-expandable unit comprises a material having a coefficient of thermal expansion greater than that of the main body of the mould; forming an annular housing comprising composite material by laying-up the composite material on an outer peripheral surface of the main body of the mould including positioning a first portion of the composite material over the thermally-expandable unit of the mould; fitting a sleeve onto the housing; and curing the housing; wherein, before or during the curing step, the first portion of the composite material of the housing is forced into a recess of the sleeve by radially-outward thermal expansion of the thermally-expandable unit of the mould so as to fasten the sleeve to the housing.
