Abstract
The utility model discloses a kind of high strength high rigidity lightweight wallboard, divide individual layer wallboard or multilayer wallboard, described individual layer wallboard is by madial wall, lateral wall, supporting-core Structure composing, madial wall, lateral wall and supporting-core structure use metal dust, utilize metal material laser gain material manufacturing technology one-body molded.Described madial wall, outer side wall structure are according to requirements set to solid construction or are set to network.Described supporting-core structure can be different according to requirement of strength different designs structure, adopt all kinds of lightweight supporting construction, comprise honeycomb, support bumper structure, for support thick stick connecting portion, adopt integrated little medicine ball structural strengthening.This lightweight wallboard, madial wall, lateral wall, supporting-core three class basic structure are combined into an entirety, because outboard sidewalls adopts metal material, better than composite shock resistance, due to the special tectonic of metallic support core, lighter than metal wallboard, rigidity is higher, possesses the advantage of metal and composite two kinds of wallboards.
Description
Technical field
This patent belongs to aerospace structure design, relates to the design of high strength high rigidity lightweight wall panel structure.
Background technology
Wall panel structure is widely used in the structure such as outer surface covering, fuel tank wallboard, deckle board, beam slab of aerospace flight vehicle, and being the important component part of Flight Vehicle Structure, is a modal class formation form.In modern aerospace structural design, wall panel structure is mainly divided three classes: metal wallboard, laminated composite wallboard, the sandwich wallboard of composite.Metal wallboard structure mainly divides two kinds, and a kind of version adopting thin metal plate to add riveted joint section bar, this kind of construction panels exists poor rigidity, type quality and is comparatively difficult to ensure card, adds the problem such as staking process and connector weight.Another kind of metal wallboard structure adopts thick aluminium sheet, and by the mode of machining, integrated machine addition metal wallboard, it is good that this kind of integrated machine adds metal wallboard type quality, and overall stiffness and strength is better.But owing to adopting machine adding method, by the restriction of lathe minimum process thickness, wall panel thickness is thicker, in part manufacture process, stock utilization is low simultaneously.Along with composite is in aerospace a large amount of use, laminated composite wallboard is more and more used, and lamination wallboard need use the artificial or machinery paving on mould of material prepreg, and then heating cure is shaping.Large-scale lamination wallboard manufacturing process is complicated, and manufacturing cost is high, and in production process, quality is uncontrollable, easy existing defects.Simultaneously due to the characteristic of composite, impact resistance is poor.The sandwich wallboard of composite is that increase sandwich of layers, it exists the problem of impact resistance difference equally for improving rigidity in the middle of lamination wallboard laying.How to design, adopt which kind of material, use which kind of the most effective manufacture method thus reach the covering of aerospace flight vehicle, wall panel structure weight is the lightest, strength and stiffness are the highest, is the most difficult problem that aerospace structure designer faces always.
Summary of the invention
The purpose of this utility model is, adopt new manufacturing process technology, for aerospace flight vehicle provides a kind of high strength high rigidity lightweight wall panel structure of brand new class, under the prerequisite meeting traditional wallboard using function, reach the requirement of wallboard lightweight, Rigidity and strength excellentization, possess good shock proof ability simultaneously.
The technical solution of the utility model is: a kind of high strength high rigidity lightweight wallboard, divide individual layer wallboard or multilayer wallboard, multilayer wallboard is the superposition of individual layer wallboard, inner containing sandwich wall, the limit, left side of described lightweight wallboard and right edge have two kinds of patterns to be vertical-type and apsacline, it is characterized in that: described individual layer wallboard is by madial wall, lateral wall, supporting-core Structure composing, described madial wall, lateral wall and supporting-core structure use metal dust, utilize metal material laser gain material manufacturing technology one-body molded.Described madial wall, outer side wall structure are according to requirements set to solid construction or are set to network.Described supporting-core structure can be different according to requirement of strength different designs structure, adopt all kinds of lightweight supporting construction, comprise honeycomb, support bumper structure, for support thick stick connecting portion, adopt integrated little medicine ball structural strengthening.
This high strength high rigidity lightweight wallboard, madial wall, lateral wall, supporting-core three class basic structure are combined into an entirety, because outboard sidewalls adopts metal material, better than composite shock resistance, due to the special tectonic of metallic support core, lighter than metal wallboard, rigidity is higher.Simultaneously because the number of plies is adjustable, the design plasticity of wallboard is stronger.Possess the advantage of metal and composite two kinds of wallboards, and shaping without mould fast free, stock utilization is high, the manufacturing cycle is short, production cost is low, is a kind of creationary wall panel structure form completely newly.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1 to 4, it is a kind of various structures of high strength high rigidity lightweight wallboard, to meet the needs be connected with all kinds of structural framework, this lightweight wallboard divides single or multiple lift, the limit, left side of lightweight wallboard and right edge have two kinds of patterns to be vertical-type and apsacline, can require to select according to environment for use, rigidity, intensity, shock resistance etc.Individual layer wallboard is made up of madial wall 1, lateral wall 2 and supporting-core 3, and multilayer wallboard is the superposition of individual layer wallboard, inner containing sandwich wall 4.Individual layer wallboard detailed description of the invention is: individual layer wallboard madial wall 1, lateral wall 2 and supporting-core 3 structure use metal dust, utilize metal material laser gain material manufacturing technology (3D printing technique) one-body molded manufacture.Realized the function such as shock resistance, sealing of wallboard by the outboard sidewalls 1,2 of metal, realize the high rigidity of wallboard and lightweight requirement by supporting-core 3 structure, by the one-body molded manufacture of metal material laser gain material manufacturing technology, meet the requirement of strength of wallboard.Inside and outside sidewall 1,2 structure is according to requirements set to solid construction or is set to network.Supporting-core 3 structure can be different according to requirement of strength different designs structure, adopt all kinds of lightweight supporting construction, comprise honeycomb, support bumper structure.For support thick stick connecting portion, adopt integrated little medicine ball structural strengthening.The advantage of the comprehensive conventional metals wallboard of the utility model and Composite Panels, merges the version of two class wallboards, designs the wall panel structure form that a class is brand-new.
Above-described embodiment; the just one of the utility model more preferably detailed description of the invention, the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model, combination and replacement all should be included in protection domain of the present utility model.
