Description
Technical field
The utility model belongs to curing molding technical field, and in particular to one kind can be used for composite material Ω stringer co-curings
Molding air bag.
Background technology
Ω type stringers are a kind of parts of semi-closed structure, compared to traditional drum, c-type and L-type stringer, Ω stringers
Difficulty bigger is molded, generally use male mould forming mould individually cures Ω stringers, then by being glued co-curing or second bonding
Method is connected with covering, and the forming process of entire part at least needs into tank to cure twice, and the production cycle is long, and cost is higher.Such as
Fruit uses co-curing forming technique, and Ω stringers can form a cavity after combine with siding, how to ensure cavity inside pressurize with
Inner surface quality is the key that Ω stringers and siding co-curing forming technique, and current solution method is using vacuum bag or solid
Rubber is placed in the cavities as core, is pressurizeed, taken by the gases at high pressure in autoclave or solid rubber expanded by heating
Obtained good effect.But the above method still has certain limitation.First, pressurizeed using vacuum bag easily due to vacuum
Bag is damaged and pressurizes and fails, and is even scrapped so as to cause the defects of entire part；Secondly, vacuum bag is in itself without intensity, type
Face is difficult to consistent with Ω stringer inner mold face, often there is the problem of poor to stringer R angles pressure effect in pressure process, actual
Often there is the defects of layering, hole at the product stringer R angles produced.Its type face of solid rubber core can in Ω stringers
Type face is consistent, and R angles pressure effect is preferable, but the swell increment of rubber is difficult to control, and it is excessive and lead to be susceptible to swell increment
Stringer is caused to crouch the situation that side is erected, in this case stringer crouch side can because be pressurized deficiency due to there are internal flaw, and not
It can theoretically prove that the pressure that rubber applies stringer due to expanded by heating meets design document requirement always, in civil aircraft
In the manufacturing process of part, solid rubber mandrel molding scheme tends not to be readily accepted by customers.The utility model provides one kind
Thin-walled rubber air bag can make product be pressurized uniform by the air bag, inside and outside good quality, in theory in practical operation
Meet Element Design drawing requirement, disclosure satisfy that the requirement of civil aircraft Airworthiness Examination, the failures such as vacuum leak occur and be easy to
It excludes, does not influence part quality, high recycling rate, there is higher economic benefit.
Utility model content
The technical problem to be solved by the present invention is to provide one kind can be used for composite material Ω stringer co-curings molding
Air bag.
The technical solution of the utility model：
One kind can be used for the molding air bag of composite material Ω stringer co-curings, which is enhanced using fibre reinforced fabric
Vulcanization rubber is made, and is molded by metal negative and positive assembling die, and section is consistent with Ω stringer inner mold face；The air bag includes
Outer half finished rubber layer, R angles reinforcing fiber, fibre reinforced fabric, interior half finished rubber layer and vacuum bag；The air bag is most
Outer layer is outer half finished rubber layer, and section is consistent with Ω stringer inner mold face；In the R Angle Positions of air bag, i.e., positioned at outer unvulcanized
R angles reinforcing fiber is pasted at rubber layer inner wall rib, ensures that air bag is closed with Ω stringer inner mold face paste；The interior half finished rubber
Layer is located in outer half finished rubber layer, positioned at cap waist position one layer of fibre reinforced fabric of laying of interior half finished rubber layer, carbon
Fiber-reinforced fabric is compacted at interior half finished rubber layer and outer half finished rubber interlayer；Vacuum bag is filled in interior half finished rubber layer
In.
The beneficial effects of the utility model：
0 ° of fibre reinforced of air bag R Angle Positions has certain intensity, can be good at and Ω stringer inner mold face pastes
It closes, ensures the pressure effect of each position including R Angle Positions.Air bag itself has air-tightness, liner vacuum bag, solid
Connected during change by vacuum bag with gases at high pressure in autoclave, intracapsular pressure and tank pressure are consistent, pressure effect it is preferable and
Meet civil aviaton's requirement.If it find that vacuum bag is revealed in airtight detection before curing, vacuum bag can be replaced immediately, is not influenced
Even if the encapsulation combination of entire part, breakage occurs in vacuum bag in the curing process, due to the air-tightness of air bag itself, can also protect
Demonstrate,prove the normal cure of part.Vacuum bag is replaced after each use, air bag is reusable.
