The invention provides a composite
honeycomb sandwich structure for an oversized high-precision single-curved reflection panel. The composite
honeycomb sandwich structure comprises three
layers of hard aluminum plates, two
layers of
aluminum honeycomb cores and a sectional material framework for connecting and supporting. A total realization process comprises determination of a panel partitioningscheme, splicing of the three
layers of hard aluminum plates, determination of a slotting scheme, calculation of shielding, unfolding of the panel, calculation of nailing height, positioning of the three layers of hard aluminum plates, the panel and the sectional material framework on a high-precision nailing
bed, production of a working plate
solid mold, pre-stretching and molding of the sectional material framework,
notching of the
honeycomb cores, adjustment of the nailing
bed, layer-by-layer pavement of the sandwich structure and cementing and formation under vacuum negative pressure. Thecomposite honeycomb sandwich structure is applied to
engineering, and the formation rigidity and profile precision stability of the oversized high-precision single-curved reflection panel can be effectively improved; a production target of an oversized and single-curvature high-precision, large-rigidity and light-weight reflection panel applicable to a column surface near field is realized.
