Description

One kind can be used for the molding air bag of composite material Ω stringer co-curings
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.

Embodiment
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 4, R angles reinforcing fiber 5, fibre reinforced fabric, interior half finished rubber layer and vacuum bag;The air bag Outermost layer is outer half finished rubber layer 4, and section is consistent with Ω stringer inner mold face;In the R Angle Positions of air bag, that is, it is located at outer non-sulphur Change and R angles reinforcing fiber 5 is pasted at 4 inner wall rib of rubber layer, ensure that air bag is closed with Ω stringer inner mold face paste;Described is interior unvulcanized Rubber layer is located in outer half finished rubber layer 4, and cap waist position one layer of fibre reinforced of laying positioned at interior half finished rubber layer is knitted Object, fibre reinforced fabric are compacted between interior half finished rubber layer and outer half finished rubber layer 4;Vacuum bag is filled in interior unvulcanized In rubber layer.
A kind of preparation method available for the molding air bag of composite material Ω stringer co-curings, step are as follows:
(1) the half finished rubber layer 4 outside laying in metal die;
(2) in air bag cap waist position one layer of fibre reinforced fabric of laying;
(3) 0 ° of R angles reinforcing fiber 5 is filled in air bag R Angle Positions;
(4) half finished rubber layer in laying is continued, compacting is put into vacuum bag, high temperature vulcanized after encapsulation.
