Abstract
A kind of structure that vacuum bag is reused belongs to composite and manufactures field, comprise putty bar, mould, vacuum bag, also comprise tack reinforcing strip, described tack reinforcing strip is pasted onto outside vacuum bag, and trend and the putty bar of tack reinforcing strip move towards to mate consistent.Disclosed structure can make vacuum bag when not affecting sealing, reuse, tack reinforcing strip no doubt can strengthen the intensity of vacuum bag, and simultaneously, tack reinforcing strip, by making vacuum bag can not torsional deformation, makes the influenced of the bonding relation indirect between putty with vacuum bag, after vacuum bag uses, even if circumstance complication, putty bar also can be made together can to take off with vacuum bag, and this technique effect that tack reinforcing strip affects putty and vacuum bag is unexpected.Vacuum bag can reuse the production cost not only can saved in composite material shaping process, can also reduce pollution on the environment in waste and old vacuum bag removal process, protection of the environment.
Description
Technical field
The utility model belongs to composite and manufactures field, is specifically related to the structure that vacuum bag can be made in a kind of composite manufacturing process to reuse.
Background technology
Manufacture in shaping technology field at composite at present, no matter be prepreg forming technique, or wet-forming technique (also claims liquid composite molding technology (being called for short LCM), in the technique such as resin transfer moulding, vacuum assisted resin transfer molding (VARTM), resin infiltration molding process (SCRIMP) in, the use of vacuum bag is essential.Particularly in prepreg moulding process, the utilization rate of vacuum bag is very high, and therefore, the recycling rate of waterused improving vacuum bag is most important.
In real work, vacuum bag utilizes putty bar fixing in a mold, vacuum bag is bonded on putty bar, then form closed space between mould, putty, vacuum bag, workpiece is placed between closed space, making workpiece obtain continual and steady pressure by vacuumizing pressurization, being used for getting rid of the escaping gas produced when the air existed in composite reacts with gummed.And the thorough degree of exhaust, directly affect the surface quality after Workpiece shaping and intensity.
And the resin in prepreg moulding process in prepreg is solid-state form, during laying, gas is between layers difficult to get rid of, and which floor needs often to spread and will make vacuum bag and carry out pre-compacted.And make vacuum bag at every turn and all will use the vacuum film of some and corresponding putty bar.This not only adds the amount of labour, and brings too high, unnecessary production cost.
There is a kind of preparation method of the silica gel under vacuum bag reused can improve the utilization rate of vacuum bag in prior art, but the method cannot ensure all reliably even of pressurization, so range of application is not very extensive when the part that curvature is excessive or complex-shaped makes.And the effect of putty bar is sealing, when curvature is excessive or complex-shaped, use once, take vacuum bag off, vacuum bag can torsional deformation, and coating performance between putty bar is just bad.If increase intensive aspect on putty bar surface, the sealing of putty bar can be affected, if strengthened in putty bar inside, can cost be increased again.
Utility model content
For vacuum bag in solution prior art is when tearing vacuum bag, due to putty bar and vacuum film insufficient strength, produce gross distortion, cannot continue the technical problem using, cause production cost higher, the utility model provides a kind of vacuum bag recycling structure.
A kind of structure that vacuum bag is reused, comprise putty bar, mould, vacuum bag, putty bar is bonded on mould, vacuum bag is crimped on putty bar, seal cavity is formed between mould, putty bar, vacuum bag, it is characterized in that: also comprise tack reinforcing strip, described tack reinforcing strip is pasted onto outside vacuum bag, and trend and the putty bar of tack reinforcing strip move towards to mate consistent.
Structure disclosed in the utility model can make vacuum bag when not affecting sealing, reuse, tack reinforcing strip no doubt can strengthen the intensity of vacuum bag, and simultaneously, tack reinforcing strip is by making vacuum bag can not torsional deformation, make the influenced of the bonding relation indirect between putty with vacuum bag, after vacuum bag uses, even if circumstance complication, also putty bar can be made together can to take off with vacuum bag, and this technique effect that tack reinforcing strip affects putty and vacuum bag is unexpected.Vacuum bag can reuse the production cost not only can saved in composite material shaping process, can also reduce pollution on the environment in waste and old vacuum bag removal process.Can protection of the environment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is made an explanation:
A kind of structure that vacuum bag is reused, comprise putty bar 2, mould, vacuum bag 1, putty bar 2 is bonded on mould, vacuum bag 1 is crimped on putty bar 2, seal cavity is formed between mould, putty bar 2, vacuum bag 1, it is characterized in that: also comprise tack reinforcing strip 3, described tack reinforcing strip 3 is pasted onto outside vacuum bag 1, and trend and the putty bar 2 of tack reinforcing strip 3 move towards to mate consistent.
During use, even if vacuum bag 1 is at complex environment, namely when the part that processing curvature is excessive or complex-shaped, the corresponding curvature of mould is equally comparatively large, and when complex-shaped, the sticking effect between vacuum bag 1 and putty is bad, even can affect vacuum.And the perfection between putty and vacuum bag 1 is fitted now to use tack reinforcing strip 3 to ensure, realize the object vacuumized.
Degree is fitted tightly when the reinforcing strip of tack can ensure vacuum bag 1 distortion between putty and vacuum bag 1, when vacuum bag 1 is finished using, when needing vacuum bag 1 and putty to take off from mould, vacuum bag 1 is stressed yielding, and distortion directly affects life-span and the service property (quality) next time of vacuum bag 1.Tack reinforcing strip 3 for this reason in the utility model selects fabric bar.After selecting fabric bar, the fiber of fabric bar has good tensile resistance because of its structure, and the fabric bar of tack is attached to outside vacuum bag 1, when taking vacuum bag 1 off, the most easily stretch stressed place by the fabric bar of tack attachment reinforcement, then vacuum bag 1 is not fragile.Realize the recycling of vacuum bag 1.
When using vacuum bag 1, the putty width bonding with vacuum bag 1 is about between 10 ~ 20mm, for this reason, tack fabric is cut into the fabric bar of 10 ~ 30mm mm wide.
Tack fabric is pasted onto outside vacuum bag 1, is clipped in the middle by vacuum bag 1 together with putty.
When the distance of tack fabric transverse side distance putty central shaft is identical, the effect of pasting reinforcement is best.
When the distance of tack fabric transverse side distance putty central shaft is 3 ~ 5mm, cost performance is the highest, both ensure that the intensity of vacuum bag 1, has saved tack fabric web material simultaneously.
Protection domain of the present utility model is not limited only to the technical scheme disclosed in detailed description of the invention part, and all tack reinforcing strip that utilizes make the reusable technical scheme of vacuum bag all fall into protection domain of the present utility model.
