Inventor

A sandwich panel is any structure made of three layers: a low-density core, and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required.

Sandwich panel with closed edge and methods of fabricating

InactiveUS20090255213A1Great strength to weight ratioLight weightLaminationLamination apparatusEngineeringSandwich panel

The edge of a construction element, such as a sandwich panel having a core and two outer layers, is closed such that forces acting on the construction element are directed to the outer layers and generally not through the panel core. A portion of the core may be removed to define a cavity within the construction element. A bonding material closes the edge by filling the cavity and forming a new edge that is substantially coplanar to the edges of the outer layers. The edge also can be closed by inserting the edge into a U-profile bracket and connecting the outer layers of the panel to side walls of the U-profile bracket.

InactiveCN111876118AHigh tensile strengthHigh impact strengthMacromolecular adhesive additivesEpoxy resin adhesivesFiberCarbon fibers

The invention discloses a lightweight high-toughness military shelter structural adhesive and a preparation method thereof. The structural adhesive is prepared by compounding a component A and a component B according to a mass ratio of 100 : 20-50, wherein the component A comprises, by mass, 70-100 parts of epoxy resin, 10-20 parts of an itaconic acid-based hyperbranched polyester ether active toughening agent, 5-20 parts of a diluent, and 20-30 parts of an inorganic filler; and the component B is prepared from the following components in parts by mass: 30-80 parts of modified cardanol-based polyamine, 10-30 parts of polyamide and 1-2 parts of a coupling agent. The military shelter structural adhesive formula is suitable for bonding of honeycomb sandwich panels, polyurethane foam sandwichpanels, aluminum skin or carbon fiber plate skin and the like. The adhesive is low in viscosity, simple in curing process, high in peeling and shearing strength, high in high-temperature creep resistance and stable in quality; main raw materials are derived from renewable resources, so that the military shelter structural adhesive is more environmentally friendly, low in cost, easy to obtain and suitable for large-scale popularization and application. The invention has great application prosepct.

Preparation method of negative thermal expansion metamaterial sandwich panel based on topological optimization design

PendingCN114091124AMultiple Design FreedomGeometric CADDesign optimisation/simulationThermal dilatationElement model

The invention discloses a preparation method of a negative thermal expansion metamaterial sandwich panel based on topological optimization design. The preparation method comprises the following steps: (1) establishing an overall structure model of the negative thermal expansion metamaterial sandwich panel; (2) establishing a metamaterial-based structure finite element model for filling the sandwich panel; (3) inputting basic material parameters, constraint values and a finite element model of the metamaterial-based structure; (4) calculating values of an equivalent thermal expansion coefficient and an equivalent elastic modulus of the metamaterial and corresponding partial derivatives; (5) establishing an explicit optimization model, and solving through linear programming; (6) judging whether the equivalent thermal expansion coefficient convergence precision is met or not, and if the equivalent thermal expansion coefficient convergence precision is not met, returning to the fourth step; and if the equivalent thermal expansion coefficient convergence precision is met, inverting the optimal continuous topological variable until the equivalent elastic modulus requirement is met, to obtain an optimal topological structure; and (7) modeling the filled metamaterial, and filling the negative thermal expansion metamaterial in a periodic array between clamping plates to form the negative thermal expansion sandwich plate. The method has more design freedom degrees and better performance.
