Description
Technical field
Present invention relates particularly to a kind of assembling die of full composite material ripple Cylindrical Sandwich Shells.
Background technology
With the development of Aeronautics and Astronautics and each engineering field, structure lightened design is particularly important, sandwich structure tool
The mechanical property for having higher specific strength, specific modulus etc. outstanding, is that grid adds currently used for the cylindrical shell of large space structure mostly
Muscle structure, including without skinned mesh reinforced structure, inside panel grid reinforced structure, exterior skin grid reinforced structure, interior exterior skin
Grid reinforced structure, its complicated process of preparation, for Composite Cylindrical Shell, are difficult to realize the effectively connection of eyelid covering and panel.
For Stiffened cylindrical shell, its more ripe technique is mainly carbon fiber winding technique and post forming
Technique.Pressure stochastic distribution can realize the mass of component and automated production, but the reinforcement that fiber winding is prepared is justified
Post shell has some shortcomings, such as cellosilk is continuous laying winding on mould, then necessarily deposit in rib infall
In the overlap of fiber, the fibre weight of non crossover point part is caused to have very big difference with the fibre weight of cross point part so that non-
The fiber volume fraction of zone of intersection reinforcement is less than 50%.In addition all there is molded body with mould when fiber winds and solidifies
Directly contact, inevitably causes the damage of product during the curing molding demoulding.At present, for prepared grid reinforcement is multiple
Rib of the condensation material cylindrical shell in the hand of spiral, its modulus are about the 80% of traditional unidirectional composite material, and compressive strength is reduced to
The 40% of only traditional unidirectional composite material.Secondary curing molding is also to carry out on the basis of fiber winding technology, therefore
This technique has the shortcomings that to avoid fiber from winding.
For pyramid dot matrix structure, its preparation technology is more complicated, cannot winding core using carbon fiber winding technology
Shape.Also there is the exploration of some time with regard to the people that prepare of lattice structure, spell including rod member packaging technology, Water Cutting single pole
Technique, Water Cutting interlocking packaging technology is connect, is interted weaving, RTM mold technique etc., but is all difficult to structure mass
Automatically producing, and prepare large-scale component has very big difficulty.Also scholar starts out prepreg integral forming process and prepreg
Secondary forming process and interlocking packaging technology, wherein interlocking packaging technology are built upon on grid basis, are to realize golden word
High-strength aluminum alloy is selected in the mass production of tower dot matrix cylindrical shell structure, its core material, with wire cutting mass production aluminum
Alloy lattice fuse, eyelid covering are composite, using circular dies pressure sintering molding.Using the connection side being glued between the core of face
Formula, inside and outside panel connect rear stick carbon fiber piece and reinforced sheet to make up the defect of structure.
The content of the invention
It is an object of the invention to provide a kind of assembling die of full composite material ripple Cylindrical Sandwich Shells, to solve existing system
Lack special mould during standby full composite material ripple Cylindrical Sandwich Shells, be difficult to realize eyelid covering dough-making powder using existing during other moulds
The effectively connection of plate, the shortcoming that cannot avoid fiber winding, complicated process of preparation are difficult to the problem of mass production.
The present invention is adopted the technical scheme that for solving above-mentioned technical problem：
Scheme one：A kind of assembling die of full composite material ripple Cylindrical Sandwich Shells, it include stem stem, matched moulds fixture, two
Individual end cap, multiple interior side core bar bodies and multiple outboard wick bar bodies, the stem stem is split-type hollow cylinder, described two end caps point
Top surface and the bottom surface of stem stem be not detachably connected on, the axial direction of multiple interior side core bar bodies and multiple outboard wick bar bodies along stem stem
It is arranged alternately on the excircle of stem stem, between the outboard wick bar body that side core bar body is adjacent in each, gap is arranged, described
Matched moulds fixture is cylindrical shape, and the matched moulds fixture is sleeved on the stem stem with multiple interior side core bar bodies and multiple outboard wick bar bodies
On, the inwall of the matched moulds fixture is arranged with interior side core bar body space, and inwall and the outboard wick bar body phase of the matched moulds fixture are pasted
Tightly.
Scheme two：A kind of assembling die of full composite material ripple Cylindrical Sandwich Shells, it includes stem stem, matched moulds fixture and two
Individual end cap, the stem stem are split-type hollow cylinder, and the outer surface of the stem stem is the curved surface of the radially uniform convex-concave in direction,
The shape of the matched moulds fixture inwall is arranged with the symmetrical shape of the outer surface of stem stem, and described two end caps are detachably connected respectively
In top surface and the bottom surface of stem stem, the matched moulds fixture is sleeved on outside stem stem.
Present invention beneficial effect compared with prior art：
1st, the present invention is the assembling die for preparing full composite material ripple Cylindrical Sandwich Shells, and the present invention includes two sides
Case, scheme one are longitudinal combination mould, in scheme one two end caps be disposed to it is solid respectively from the top surface of stem stem and bottom surface
Determine the basic structure of stem stem, prevent the stem stem of split-type from shifting because lacking stable fixing component, it is ensured that core column structure
Stablize indeformable；The arrangement mode of multiple interior side core bar bodies and multiple outboard wick bar bodies on stem stem effectively realizes that longitudinal convex-concave rises
The ripple struction of volt, prepreg is put between interior side core bar body and outboard wick bar body, so that prepreg is integrally formed to be formed
Longitudinal ripple fuse.Being disposed to of matched moulds fixture clamps and fixed stem stem, prepreg, multiple interior side core bar bodies and multiple outer
Side core bar body.
2nd, in the present invention, scheme two is ring assembling die, and in scheme two, two end caps is disposed to from the top of stem stem
Face and bottom surface fix the basic structure of stem stem respectively, and matched moulds fixture is to pressurize and fix all in which to prepreg molding
Internal component parts.
3rd, the present invention omits the step of fiber winding prepares full composite material ripple Cylindrical Sandwich Shells used in traditional handicraft,
The step of effectively prevent ups and downs ripple struction and be difficult to fiber and wind, the longitudinal wave for finishing will be prepared with pressure sintering
Stricture of vagina fuse and panel form full composite material longitudinal ripple Cylindrical Sandwich Shells by linking together by the way of being glued, together
Reason, ring ripple fuse dough-making powder plate form full composite material longitudinal ripple interlayer circle by linking together by the way of being glued
Post shell.
4th, present invention process is realized simply, and operation is simple and motility strong, by interior side core bar body and outboard wick
Add processing release paper between bar body or silica gel piece can prepare the cylindrical shell thinner than preset clearance, can so pass through one set of die
Prepare the different cylindrical shell of thickness.
5th, in the present invention, the fuse prepared and panel splicing area can be controlled, so as to realize the effective of fuse and panel
Connection, makes the annexation of the two stably firm.
6th, the present invention is cheap for manufacturing cost, is capable of achieving mass production.
