The utility model discloses not only having solved the technological problem of the leading -in method in vacuum than difficult super thick combined material panel of realization or goods preparation, having enlarged the range of application of the leading -in method in vacuum, the while also provides a thinking for the low cost manufacturing of super thick combined material panel or goods.
Description
Technical field
This utility model relates to a kind of vacuum introductory technique and prepares super thick composite board device.
Background technology
In the various fields such as fibre reinforced composites are a kind of novel high performance materials, have specific strength high, and many excellent characteristics such as specific modulus is big, corrosion-resistant are used for Aero-Space, track traffic, automobile, Leisure Sport.The moulding process of composite mainly includes autoclave forming process at present, pultrusion molding process, winding shaping process, resin transfer molding, many moulding processs such as vacuum importing, wherein vacuum guiding and forming technique is a kind of low cost, operates easy liquid molding process, has bigger advantage in the manufacture of composite product.But because of the limitation of its process characteristic, for thicker, more complicated composite product is relatively difficult to achieve, also limit its extensive application.
The principle of vacuum guiding and forming technique is at one atm, by resin infusion to reinforcement, by the flowing of resin, infiltration, gradually infiltration reinforcement fiber.Resin wetting fibre mainly has two active forces, and first, the gravity of resin makes resin gradually permeate below preform, reaches the purpose of wetting fibre；Second, the interaction force between resin and fiber, make resin and fiber reach infiltration.During resin infiltrates with fiber, As time goes on, the resistance that resin advances becomes larger, and makes the difficulty of resin wetting fibre increase, therefore relatively big for thickness, and the composite product that shape is more complicated, vacuum imports relatively difficult to achieve.
The problem of above-mentioned existence, prepares in vacuum importing and should give enough attention in composite product, and should solve the technical barrier of reality.
Utility model content
A kind of vacuum introductory technique that this utility model provides prepares super thick composite board device, for solving the technical barrier of vacuum introductory technique super thick relatively difficult to achieve composite board product, expand the range of application of vacuum introductory technique, reduce the cost that super thick composite board manufactures.
Technical solution of the present utility model is:
A kind of novel vacuum introductory technique prepares super thick composite board device, including mould, die surface has been coated with lower permeable medium, bottom knockout cloth, preform, upper release cloth, upper permeable medium and vacuum bag successively, arranging sealant tape in mould surrounding, vacuum bag is sealed by sealant tape, and vacuum bag is provided with resin pipeline and exhaust pipe, resin pipeline connection glue injection pipe, injected rubber hose connects resin barrel, and exhaust pipe connects exhaust tube, and exhaust tube connects vacuum system.
Described exhaust tube is enclosed with single permeable membrane.
Vacuum introductory technique of the present utility model prepares super thick composite board device, solve vacuum introductory technique super thick relatively difficult to achieve composite board or technical barrier prepared by goods, expanding the range of application of vacuum introductory technique, the most also the cost degradation manufacture for super thick composite board or goods provides a thinking；Meanwhile, for the resin system that gel time is short, use this utility model can realize its application in vacuum guiding and forming technique.
Accompanying drawing explanation
Fig. 1 is the overall schematic that this utility model is implemented.
Wherein: 1-vacuum system；2-exhaust tube；3-resin barrel；4-injected rubber hose；5-sealant tape；6-vacuum bag；7-preform or prepattern fabric；The upper permeable medium of 8-；The upper release cloth of 9-；10-bottom knockout cloth；Permeable medium under 11-；12-mould.
Detailed description of the invention
Preferred embodiment of the present utility model is described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of novel vacuum introductory technique prepares super thick composite board device, including mould 12, mould 12 surface has been coated with lower permeable medium 11, bottom knockout cloth 10, preform 7, upper release cloth 9, upper permeable medium 8 and vacuum bag 6 successively, in mould 12 surrounding, sealant tape 5 is set, vacuum bag 6 is sealed by sealant tape 5, resin pipeline 13 and exhaust pipe 14 it is provided with on vacuum bag 6, resin pipeline 13 connection glue injection pipe 4, injected rubber hose 4 connects resin barrel 3, exhaust pipe 14 connects exhaust tube 2, and exhaust tube 2 connects vacuum system 1.
nullMould 12 removing surface is clean，Surrounding at mould 12 sticks sealant tape 5，Then the lower permeable medium 11 reduced is coated with on the mold 12，Then on lower permeable medium 11, bottom knockout cloth 10 it is coated with successively，Preform 7、Upper release cloth 9、Upper permeable medium 8，Vacuum bag 6 is arranged resin pipeline 13 and exhaust pipe 14，Injected rubber hose 4 is connected together with resin pipeline 13，Single permeable membrane is used to be wrapped up by exhaust tube 2，Then exhaust tube 2 is connected with exhaust pipe 14，Exhaust tube 2 connects vacuum system 1，Vacuum bag 6 is sealed with sealant tape 5，By vacuum system evacuation，During evacuation，In place of arranging turning，Prevent fabric from building bridge，Detection vacuum，Closure air leakage point，The resin prepared is imported in resin barrel 3，Perfusion resin，After treating resin complete wetting fiber，Injected rubber hose 4 is taken out from resin barrel 3，And seal.
After perfusion resin, the resin of preform upper surface passes through gravity and the downward permeable fiber of surface reaction forces, and the resin of preform lower surface permeates up fiber by surface reaction forces, shortens the injecting glue time, improves the success rate of composite board.
In order to ensure that resin, during dipping fiber, is not drawn out of, single permeable membrane is used to be wrapped up by exhaust tube.
