    摘要: A method and apparatus for strong bonded wide joints for cryogenic applications. In one advantageous embodiment, an apparatus may comprise a three-dimensional preform and a plastic matrix. The plastic matrix may be impregnated in the three-dimensional preform to form a softening strip that may be capable of remaining flexible at a temperature at which a gas may have a liquid form.

    摘要: An apparatus comprising a first structure, a second structure, a first layer, and a second layer. The first structure has a first plurality of channels extending towards a number of edges of the first structure. The second structure has a second plurality of channels extending towards a number of edges of the second structure. A first side of the first structure is connected to a first side of the second structure. The first plurality of channels and the second plurality of channels have an orientation with respect to each other. The first layer is connected to a second side of the first structure. The second layer is connected to a second side of the second structure.

    摘要: A method for joining fittings to a composite sandwich shell edge includes laying up an inner facesheet and positioning a wrapped flute mandrel on top; applying a layer of adhesive on the inner facesheet and positioning spacer-supported fittings on top; applying adhesive over the co-bonded fittings and laying up an outer facesheet forming an assembly; curing the assembly under heat and pressure; removing the fittings by first collapsing the spacers and removing the flute mandrel; placing an adhesive layer on the fittings with collapsible spacers inserted therein; reinserting the fittings between the inner and outer facesheets and effecting bonding and curing; and removing the spacers from the fittings by collapsing the spacers.
