Abstract
The utility model discloses a circular metalwork and fiber reinforcement combined material's connection structure, including circular metalwork and combined material board, be equipped with connecting device between circular metalwork and the metal sheet, the connection face of metal sheet is equipped with a plurality of recesses, when the recess internal fiber spread and apply, the tow is arranged in the recess, and connect the cellosilk of tow is and disperses into the umbelliform and arranges the fibre cloth in, connecting device uses vacuum auxiliary forming technology negative pressure adsorption resin promptly and fills solidification moulding. The utility model has the advantages that: 1) the problem that the composite material plate cannot be connected with the interface of the cylindrical metal material is solved; 2) the vacuum auxiliary forming connects the fiber bundle in the groove and the fiber silk which is diverged into an umbrella shape and is arranged in the fiber cloth into a whole.
Description
Technical Field
The utility model relates to a connection mode of different components especially involves the connection structure of composite board and metal.
Background
1) The fiber reinforced composite material has the characteristics of high strength, light weight, corrosion resistance, excellent performance designability and the like, and is more and more widely applied to the high-end industry fields of aviation, aerospace, ships, automobiles and the like.
2) In the application process, the metal is inevitably required to be compounded and connected, but the thermal expansion coefficient, the modulus and other properties of the metal are greatly different from those of the metal, and when the adhesive is used in a bonding and compounding way, the interface is easy to peel off under the conditions of high and low temperature, vibration and the like for a long time, so that the adhesive becomes one of the biggest problems of limiting the compounding application of the metal and the metal material.
3) A typical fiber reinforced composite material and metal composite connection structure is designed in the scheme, and the problem that a bonding interface of the fiber reinforced composite material and metal is easy to peel off can be effectively solved.
As shown in fig. 1, the metal member is directly connected to the fiber-reinforced composite material, and the interface between the metal member and the fiber-reinforced composite material is easily peeled off by high and low temperatures, long-term vibration, and the like.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a simple structure, firm in connection's composite material board and metal sheet's connection structure.
The technical scheme of the utility model is that:
the utility model provides a connection structure of circular metalwork and fibre reinforced composite, includes circular metalwork and composite board, is equipped with connecting device between circular metalwork and the composite, and the face of connecting of circular metalwork is equipped with a plurality of recesses, and when the fibre was spread and is covered in the recess, the tow was arranged in the recess, and the cellosilk of connecting the tow is in dispersing into the umbelliform and arranges the fibre cloth in, and connecting device uses vacuum assisted molding technology negative pressure adsorption resin infusion solidification shaping promptly.
Further, the smooth surface between the circular metal piece and the composite material plate is changed into a rough surface.
Further, the connecting interface of the circular metal piece and the composite plate is circular metal piece, composite plate and circular metal piece.
The utility model has the advantages that:
1) the problem that the composite material plate cannot be connected with the interface of the cylindrical metal material is solved;
2) the vacuum auxiliary forming connects the fiber bundle in the groove and the fiber silk which is diverged into an umbrella shape and is arranged in the fiber cloth into a whole.
3) The rough surface greatly increases the bonding area and improves the bonding strength.
4) The round metal piece-composite material plate-round metal piece are bonded to achieve the purpose of composite application.

Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 2, the following beneficial design is provided at the connection interface of the circular metal piece and the composite material:
1) a certain number of grooves 3 are formed in the contact surface of the circular metal piece 2 and the composite material 1, so that the bonding area is increased, and the composite material is embedded and connected;
2) the bonding interface is changed from a smooth surface to a rough surface, so that the bonding area is greatly increased, and the bonding strength is improved;
3) when the fibers in the grooves are paved, the fibers are wound in the grooves 3 and are diverged into an umbrella shape, as shown in a schematic diagram in fig. 3, the diverged fibers 32 and the fiber cloth 33 are paved in a staggered mode, and then the fibers 32 and the fiber cloth 32 are connected into a whole by means of vacuum forming. By the method, the fiber in the groove and other fiber reinforced composite materials are organically connected into a whole; by adopting a vacuum auxiliary forming process and pouring and curing the negative pressure adsorption resin for forming, uniform negative pressure can be formed on the fibers, the fibers are uniformly compacted, the fibers can be effectively compacted, and the fibers are prevented from being unsmooth in contact with metal.
The vacuum forming of the utility model can adopt Chinese patent publication No. CN107234839A, the name of the invention is: the technical scheme of the composite plate of the marine sonar air guide sleeve and the preparation method thereof or other related vacuum forming technical schemes disclosed by the company.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
