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 assembly forming tooling, and the technique using forming frock production beam mould component.
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
