Problems solved by technology

[0002] At present, in the production of fiber composite products, in order to increase the added value of fibers, due to different products, some auxiliary materials will be added during the product design process, such as aramid paper, aluminum honeycomb panels, iron, aluminum, steel, copper and other materials. ,Due to different physical properties, when directly combined with fibers, there will be some loosening or detachment caused by deformation or oxidation. Once the above adverse conditions occur, it will be a fatal problem for the production plant and will directly lead to the scrapping of the product. At present, most of the manufacturers adopt coarsening and increase operation meticulousness to increase quality supervision and control to deal with it, which is time-consuming and labor-intensive, but substantial problems still exist
[0003] Chinese utility model patent CN 203864890 U discloses a carbon fiber composite anti-shock bicycle front fork. The front fork is provided with a layer of aramid unidirectional cloth or angled cloth in the middle layer of the vertical pipe and the wishbone, and is molded in a molding machine. Formed by high temperature and high pressure on the stage, it is suitable for bicycle front forks, mainly for the comfort and safety of riders, and cannot solve the loosening or detachment phenomenon caused by deformation or oxidation of fiber composite products

Embodiment 1

[0045] Example 1 Molded product, combination of fiber composite cloth and aramid fiber board

[0046] Try to make a PK shot, cut the epoxy film with a thickness of 0.25mm into the desired width according to the structure, then wrap the epoxy film between the fiber composite cloth and the aramid board according to the structure, and paste the yarn according to the frame shape , sent to a hot pressing table with a temperature of 150°C, heated for 20 minutes, and then cooled with a cooling table at 30°C for 4 minutes. After demoulding, the appearance of the rough embryo is intact, and its structure is as follows figure 1 As shown, the surface is a fiber composite cloth 1, the epoxy film 2 is underneath, and the aramid fiber board 3 is underneath. This embodiment is just an example, and the aramid paper 3 can also be a metal plate. The whole material takes the aramid paper or the metal plate as an axis, and the layers are distributed axisymmetrically in a direction perpendicular ...

Embodiment 2

[0049] Example 2 Expansion material internal pressure product, fiber composite cloth and aluminum product joint

[0050] Among them, the high-energy glue comes from Xiamen Haoer New Material Co., Ltd., and the model is HR-318.

[0051] Try to make a bicycle, take an epoxy film with a thickness of 0.25mm, cut it into fiber composite cloth, epoxy sheet glue, and expansion material (high-energy glue) according to the structure, and place the epoxy sheet glue on the fiber composite material. Between the cloth and the aluminum product, paste the yarn according to the frame shape, send it into a hot pressing table with a temperature of 150°C, heat it for 60 minutes, and then cool it with a cooling table at 30°C for 10 minutes. After demoulding, the appearance of the rough embryo is intact, and its structure Such as figure 2 shown.

[0052] In the figure, the outer layer of the product is a metal plate 4, the epoxy film 2 is underneath, and the fiber composite material cloth 1 is u...

Embodiment 3

[0054] Example 3 Nylon air duct internal pressure product, fiber composite cloth and aluminum product joint

[0055] Try to make a bicycle, take an epoxy film with a thickness of 0.25mm, cut it into fiber composite material, epoxy film glue, and nylon air duct of the desired size according to the structure, and put the epoxy film glue between the fiber composite material cloth and the aluminum product During the time, the yarn is attached according to the frame shape, and it is sent into a hot press table with a temperature of 150 °C, and the nylon air duct is pressurized to 10kg / cm 2 , heated for 60 minutes, canceled the pressure of the nylon air duct, and then cooled with a cooling table at 30°C for 10 minutes. After demolding, the appearance of the rough embryo was intact, and its structure was as follows image 3 shown. In the figure, the outer layer of the product is a metal plate 4, the epoxy film 2 is underneath, and the fiber composite material cloth 1 is underneath. ...

Abstract

The invention relates to a fiber composite material containing an epoxy film and a preparation method of the fiber composite material. The fiber composite material comprises at least one layer of epoxy film, fiber composite material cloth is attached to one side of the epoxy film, and aramid paper or a metal plate is attached to the other side of the epoxy film. The fiber composite material containing the epoxy film is prepared by means of compression molding or internal compression molding. The preparation method of the fiber composite material comprises the steps of cutting, rolling, pre-forming, forming and demoulding. Through impact testing, layers of the fiber composite material containing the epoxy film are not stripped off, the material does not disengage in a fatigue test, and properties are excellent. According to the preparation method, various materials are combined and do not separate or fall off, and the advantages of various materials are achieved; technical operation is simple, the efficiency is high, technical requirements for operators are not high, and common personnel can work.
