摘要： A method of fabrication of a structure (10) is described, the structure comprising an open cell foam element (12) of metallic, refractory, ceramic and/or diamond form, and/or provided with one or more metallic, refractory, ceramic and/or diamond material coatings, the element (12) defining a plurality of interconnected cells (14), and a material (16) located within the cells (14), the material (16) having been treated, in situ, by sintering and/or infiltration, to form a continuous mesh or lattice structure (18) extending within and through the cells (14) of the open cell foam element (12). The method comprises the steps of providing an open cell foam element (12) of metallic, diamond, ceramic and/or refractory material form, and/or having one or more metallic, diamond, ceramic and/or refractory material coatings, the foam element (12) defining a plurality of interconnected cells (14), locating a material (16) within the cells (14), and treating the material16, in situ, by sintering and/or infiltration, to form a continuous mesh or lattice structure (18) extending within and through the cells (14) of the open cell foam element (12). Structures (10) fabricated using the method are also described.
