A kind of light-weight multi-layer thermally protective materials structure of the utility model design, it is characterized in that this structure comprises upper strata dot matrix sandwich board, intermediate thermal insulating layer, lower plywood and side plate and forms, welding forms the box structure between described side plate and upper strata dot matrix sandwich board and the lower plywood, and described intermediate thermal insulating layer is arranged in the vestibule that upper strata dot matrix sandwich board, lower plywood and side plate surround;
Described upper strata dot matrix sandwich board forms the triangular pyramid structure of periodic arrangement by the heating resisting metal impact briquetting, and described side plate supports accordion by extrusion modling;
Described intermediate thermal insulating layer is made of two-layer heat insulation fiber, and described two-layer heat insulation fiber comprises the alumina fibre on upper strata and the super glass wool of lower floor;
Described upper strata dot matrix sandwich board is connected at the hole in four bights pipe by soldering with lower plywood.
Technical characterstic of the present utility model and effect:
The utility model is in order to improve the mechanical property and the impact resistance of multilayer thermally protective materials structure, adopted upper strata dot matrix sandwich board, it is by the heating resisting metal impact briquetting, form the triangular pyramid structure of periodic arrangement, this design can improve the load-carrying properties and the shock resistance protective ability of structure simultaneously, the integrity and the stability that in hot environment, keep structure, realize multi-functional many integrated designs of material and structure, this makes it have broad application prospects in the aerospace craft field, satisfies aerospace craft simultaneously for heat insulation, the strict demand of aspects such as carrying and shock resistance.
Light-weight multi-layer thermally protective materials structure of the present utility model, its side plate is designed to the sheet metal of accordion, the bending deflection during with minimizing thermal stress and opposing pressurized.Upper strata dot matrix sandwich board is that high porosity truss core structure and side plate are all made by nickel-base heat resisting superalloy, and lower panel then adopts titanium alloy frame and is attached to top tinsel and makes.Described intermediate thermal insulating layer is made of two-layer heat insulation fiber.What adopted on the upper strata is the relatively large alumina fibre of density, plays a part heat insulation and maintenance thermal protection structure integrity, and what lower floor adopted is the less relatively super glass wool of density, can suppress the wherein natural convection of fluid layer fully.The design's novel light multilayer insulation structure is under similarity condition, but loss of weight is more than 25%.This structure has excellent more shock resistance and vibrationproof performance simultaneously.
