Description
Technical field
The invention belongs to composite material autoclave forming process technical fields, and in particular, to a kind of more beams of composite material
Box section co-curing molding beam mould component locating support, and the technique using the locating support Web beam die assembly.
Background technique
Autoclave (Hot Air Autoelave or writing a Chinese character in simplified form Atitoelave) be it is a kind of for polymer matrix composite at
The process equipment of type process characteristic carries out the method for moulding process autoclave molding method using this equipment.Autoclave molding
Method is to manufacture the main method of continuous fiber reinforcement same with thermosetting compound material product, is now widely used for advanced composite material knot
The molding of structure, honeycomb sandwich construction and metal or adhesive bonding of composites structure.When material forms, provided simultaneously using in autoclave
Uniform temperature and well-distributed pressure and solidify, so can be obtained, surface and internal soundness are high, and complex-shaped, area is huge compound
Material.
Autoclave molding method is one of the process that is widely used both at home and abroad at present, be mainly used for large scale, shape compared with
The manufacture of complicated Aeronautics and Astronautics FRP component, such as Skin Parts, beam, frame, various siding parts, floor and radome fairing.Autoclave at
The basic principle of type method is: by prepreg by laying requirement laying on mold, and being put into autoclave after being sealed in vacuum bag
In, by the heating of autoclave equipment, pressurization, material solidification reaction is completed, prepreg blank is made to become required shape and meet matter
Measure the process of desired component.
Carbon fiber enhancement resin base composite material has specific strength and specific modulus is high and designability is strong and is easy to whole
The advantages such as molding, therefore be widely used in aviation field, especially in terms of civil aircraft.Composites Molding Techniques are very
More, prepreg-autoclave process, in occupation of critical positions, there is co-curing with its excellent product quality, cementing altogether, secondary cementing
Etc. modes.
At home and abroad composite torsion-box structural member employed in army's civil aircraft project generallys use following several sides at present
Formula manufacture:
1, by assembly connection at box section after composite material skin and beam part are separately fabricated；
2, RTM technique；
3, rubber pneumatic bag moulding process.
In three of the above process, the 1st kind of method is using splicing tooling, the covering and beam part positioning error of box section
Greatly, it cannot be guaranteed that the depth of parallelism of depth of beam and upper and lower covering, and the manufacturing cycle is long, and cost is big.2nd kind of method and the 3rd kind of side
Method is whole co-curing molding, although shortening the period, reduces costs, not can guarantee the Forming Quality of part.2nd kind
Method requires Resin Flow very high, may be only available for specific resin system, and molding product resin gel content compared with
It is high and unstable, it is impossible to be used in the load box section structure of aircraft.3rd kind of method uses rubber pneumatic bag expandable pressurized, due to air bag
It is intracavitary in type, cause the temperature uniformity of entire product and mold poor, and there are ageing of rubber, swell increment dyscalculias etc. to ask
Topic be easy to cause pressurization uneven, and the problems such as so as to cause positional shift, bending deformation, whole box section quality cannot be ensured.
Summary of the invention
It is an object of the invention to: for the problem of the Forming Quality difference of the prior art, provide a kind of more beams of composite material
Box section co-curing molding beam mould component locating support and packaging technology；The locating support and packaging technology are existing multiple
On the basis of solidification reassembles technique, beam mould is subjected to positioning pre-assembled, and then realizes more beam box Duan Yici co-curing moldings,
And it can ensure Forming Quality.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of more beam box section co-curing molding beam mould component locating supports of composite material, are oppositely arranged including two groups
Locating support is respectively arranged at least two groups position on the locating support and is relatively fixed plate.Fixed plate is for fixing rigid type
The fixed ear of board ends.It is one group that fixed plate is opposite two-by-two, is arranged to several groups, and beam mould component and beam blank is accurately pre-
Assembly.
Since prepreg is very soft, when being assembled with beam mould component, the side of beam mould can only be placed again upward
Beam prepreg, and again in the next beam mould of beam prepreg over-assemble will appearance position deviation, and be difficult to all beams
The problem of mold and prepreg are fixed as one, thus it is unable to complete the group of beam mould component and beam blank and covering die component
Dress.By the locating support, first by beam mould component and beam prepreg pre-assembled, an entirety is precisely formed, then fixes again
Between covering die component.
Preferably, it is provided with positioning plate on the locating support, is provided with dowel hole on the positioning plate.With
In the accurate position for determining beam mould component on lower wall plate forming die.
Preferably, the locating support is made of the crossbeam and vertical beam being fixed to each other, and the fixed plate setting exists
On the vertical beam.
Further, the crossbeam and the vertical beam are orthogonal.
Further, the vertical beam is provided at least two, to meet the needs of more beam box sections.
Further, the height of the locating support is less than the height of beam mould component, will not influence upper and lower wallboard forming
Mould.
Utilize above-mentioned composite material more beam box section co-curing moldings beam mould component locating support Web beam set of molds
The technique of part, includes the following steps:
C2, outermost one group of fixed plate that the fixed ear with soft mode on the outside of rigid template is installed on to the locating support
On, and on the outside of the rigid template of the band soft mode notch towards the outside of locating support；
C4, the fixed ear of inside soft mode is installed in next group of fixed plate, and the flexible template one of the inside soft mode
Side is adjacent with soft mode on the outside of rigid template；
C6, described without soft mode on the outside of rigid template, and the notch without soft mode on the outside of rigid template is placed on rib
Towards the outside of locating support.
By said modules and step, beam blank can be assembled, so realize beam blank integrated co-curing at
Type.Wherein, the two sides of beam blank position are the combination of rigid template and flexible template, also, beam mould is provided with
One rigid template for playing the role of tieing up shape and a flexible template for playing the role of molding.
In conclusion by adopting the above-described technical solution, the beneficial effect of the present invention compared with the existing technology is:
1, beam mould component is combined by the present invention, realizes the co-curing molding of the more beam box sections of composite material,
And can guarantee accurate positioning of the beam slab part in assembling and solidification process, to guarantee the thickness and axis degree of part.
2, present invention process is easy to operate, and repeatability is strong, shortens the manufacturing cycle, reduces manufacturing cost, reaches
Weight loss effect.
