An aerospace structure and method for its construction composed of two elements having mutually opposed mating surfaces, at least one of which is irregular. The mating surfaces of the elements are fastened and compressed against a noncompressible cast-in-place void filler having complimentary shape

An aerospace structure and method for its construction composed of two elements having mutually opposed mating surfaces, at least one of which is irregular. The mating surfaces of the elements are fastened and compressed against a noncompressible cast-in-place void filler having complimentary shape to the two mating surfaces. The void filler is prepared by admixing a polymerizing matrix selected from polyesters, epoxides, polyamides, polyimides, polycarbonates, polyvinyl alcohols and organosilicone polymers and a space filling material selected from phenolic microspheres, carbon microspheres, metal coated microspheres, chopped fiberglass, alumina, fumed silica and mixtures thereof.

An aerospace structure having aerodynamic surfaces positioned in a desired orientation comprising: two structural elements, each of the structural elements having an aerodynamic surface and an abutting surface, the aerodynamic surfaces being positioned in the desired orientation thereby positioning the abutting surfaces in a mutually opposed spaced relationship, at least one of the mutually opposed abutting surfaces being irregular; a noncompressible, crack-resistant shim comprising a cured void filler, the cured void filler complementarily contoured to conform to the irregularities of the abutting surfaces and sized to fill the space therebetween, the noncompressible shim sandwiched between the mutually opposed abutting surfaces, so that no voids exist; and, at least one fastener joining and compressing the abutting surfaces against the noncompressible shim, the stresses in the structural elements adjacent the abutting surfaces being evenly distributed.
