Abstract
A method for fabricating a composite structure, in which an intermediate member is sandwiched between first and second members, is disclosed. In this method, the intermediate member is disposed along the periphery of a spatial region formed between facing surfaces of the first and second members so that the spatial region is enclosed by the intermediate member, the fluidity of the intermediate member is enhanced under an atmosphere having a predetermined pressure, and then the pressure of the atmosphere is increased to make the intermediate member flow into the spatial region.
