Description
Technical field
The invention belongs to composite autoclave forming process technical field, in particular it relates to a kind of many beams of composite
Box section co-curing shaping beam mould assembly forming frock, and the technique for making beam mould component using the forming frock.
Background technology
Autoclave (Hot Air Autoelave write a Chinese character in simplified form Atitoelave) be it is a kind of for polymer matrix composite into
The process equipment of type process characteristic, the method for moulding process is carried out autoclave molding method using this equipment.Autoclave molding
Method is the main method for manufacturing continuous lod same with thermosetting compound material product, is now widely used for advanced composite material knot
The shaping of structure, honeycomb sandwich construction and metal or adhesive bonding of composites structure.When material is molded, offer simultaneously in autoclave is utilized
Uniform temperature and well-distributed pressure and solidify, complex-shaped so it is high to can obtain surface and internal soundness, huge compound of area
Material.
Autoclave molding method is one of widely used process both at home and abroad at present, be mainly used in large scale, profile compared with
The manufacture of complicated Aeronautics and Astronautics FRP components, such as Skin Parts, beam, frame, various wallboard parts, floor and radome fairing.Autoclave into
The general principle of type method is：Prepreg is laid on mould by laying requirement, and be 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 turned into required shape and is met 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 overall
The advantages such as shaping, therefore be widely used in aviation field, especially in terms of civil aircraft.Composites Molding Techniques are very
Many, prepreg-autoclave technique, in occupation of critical positions, there is co-curing with its excellent product quality, cementing altogether, secondary cementing
Etc. mode.
The composite torsion-box structural member at home and abroad employed in army's civil aircraft project generally uses following several sides at present
Formula is manufactured：
1st, after composite material skin and beam part are separately fabricated by assembly connection into box section；
2nd, RTM techniques；
3rd, rubber pneumatic bag moulding process.
In three of the above process, the 1st kind of method is using splicing frock, the covering and beam part positioning error of box section
Greatly, it is impossible to ensure depth of beam and the up and down depth of parallelism of covering, and the manufacturing cycle is long, cost is big.2nd kind of method and the 3rd kind of side
Method is overall co-curing shaping, although shortens the cycle, reduces cost, but can not ensure the Forming Quality of part.2nd kind
Method requires very high to Resin Flow, may be only available for specific resin system, and the product resin gel content being molded 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
In die cavity, cause the temperature homogeneity of whole product and mould poor, and there is ageing of rubber, swell increment dyscalculia etc. to ask
Topic, easily causes pressurization inequality, so as to cause the problems such as position skew, flexural deformation, overall box section quality cannot be ensured.
The content of the invention
It is an object of the invention to：For prior art Forming Quality it is poor the problem of there is provided a kind of many beams of composite
Box section co-curing shaping beam mould assembly forming frock and manufacture craft；The forming frock and manufacture craft are existing multiple
Solidification is reassembled on the basis of technique, and made beam mould component can realize many co-curing shapings of beam box section, and energy
Enough ensure Forming Quality.
To achieve these goals, the technical solution adopted by the present invention is：
