<p>In one aspect of the invention there is provided a method of manufacture of an assembly comprising: forming an assembly by coupling a first component (150) to a second component (110) in spaced apart relationship therewith by means of coupling means (131); providing thermally activated seal means between the components, the first component, second component and seal means being arranged such that a gap exists between the first and second components allowing fluid flow therethrough; and subjecting the assembly to heat thereby to cause the seal means to expand and bridge the gap between the first and second components thereby to form a fluid tight seal between them. The second component may be at least partially enclosed between the first and a third component (161), and the second component may provide an aperture at a location opposite a portion of the third component whereby expansion of a seal means (112S,114S) around the aperture causes the aperture to be sealed by the seal means and said portion of the third component</p> |
