Embodiment 1

[0040] figure 1 Schematic diagram of the structure of the electroformed composite material provided for Example 1 of the present invention; please refer to figure 1 .

[0041] The electroplating composite material 100 provided in this embodiment includes a stacked metal layer 130 and a composite material layer 150. The composite material layer 150 is formed of a carbon fiber composite material. The metal layer 130 deposits a connecting portion 131 toward the surface of the composite material layer 150. The composite material The surface of the layer 150 facing the metal layer 130 has a connection groove 151 at a position corresponding to the connection portion 131 , and the connection portion 131 is located in the connection groove 151 , so that the metal layer 130 and the composite material layer 150 are fixedly connected.

[0042] The metal layer 130 is made of various materials, such as nickel, iron, and copper. In this embodiment, the metal layer 130 is made of nickel. ...

Embodiment 2

[0048] image 3 Schematic diagram of the structure of the electroformed composite material provided for Example 2 of the present invention; please refer to image 3 .

[0049] The electroplating composite material 100 provided in this embodiment includes a stacked metal layer 130 and a composite material layer 150. The composite material layer 150 is formed of a carbon fiber composite material. The metal layer 130 deposits a connecting portion 131 toward the surface of the composite material layer 150. The composite material The surface of the layer 150 facing the metal layer 130 has a connection groove 151 at a position corresponding to the connection portion 131 , and the connection portion 131 is located in the connection groove 151 , so that the metal layer 130 and the composite material layer 150 are fixedly connected.

[0050] The metal layer 130 is made of various materials, such as nickel, iron, and copper. In this embodiment, the metal layer 130 is made of nickel. ...

Embodiment 3

[0059] This embodiment provides an electroformed composite material, which has a structure similar to that of the electroformed composite material in Embodiment 2, except that the connection part of the electroformed composite material provided by this embodiment is in the shape of a barb.

[0060] Figure 5 For the enlarged structural schematic diagram of the connection part of the electroformed composite material provided in Example 3 of the present invention, please refer to Figure 5 .

[0061] The connecting portion 131 is in the shape of a barb. The connecting portion 131 includes a straight section 1311 and a bent section 1313. The straight section 1311 is vertically deposited on the surface of the metal layer 130, and the bent section 1313 is fixedly connected to the surface of the straight section 1311 away from the metal layer 130. At one end, the shape of the connecting groove 151 matches the shape of the connecting portion 131 .

[0062] The straight section 1311...

Abstract

The invention provides an electroforming composite material and a preparation method thereof, which relate to the technical field of electrodeposition and composite materials. The metal-based composite material comprises a deposited metal layer and a composite material layer which are arranged in a stacked mode. The composite material layer is formed by a carbon fiber composite material; wherein aconnecting part is arranged on the surface, facing the composite material layer, of the deposited metal layer, a connecting groove is formed in the position, corresponding to the connecting part, ofthe surface, facing the metal layer, of the composite material layer, and the connecting part is located in the connecting groove, so that the metal layer is fixedly connected with the composite material layer. The layer structure of the metal-based composite material can be firmly attached into a whole, and the metal-based composite material has good surface quality.

Description

technical field [0001] The invention relates to the technical field of electrodeposition and composite materials, in particular to an electroforming composite material and a preparation method thereof. Background technique [0002] Electroformed composite materials have the characteristics of high specific strength, specific stiffness, heat resistance, long service life and dimensional stability. They are a new generation of military materials and are mainly used for key structural parts of aerospace vehicles. [0003] The existing electroformed composite materials can improve the interfacial properties of the material through reinforcement surface treatment and surface coating. The common methods of surface coating include: electroless plating method, chemical vapor deposition method, etc. The introduction of the coating changes the original bonding state of the interface and improves the bonding strength of the interface. However, during the preparation process of this el...
