Problems solved by technology

However, due to the low TG point (glass transition temperature) of the resin and the molding process of the composite material, the working temperature of the epoxy resin-based carbon fiber composite product must be lower than the TG point of the resin, otherwise, the resin will soften and deform, resulting in The entire composite product is deformed and scrapped, thus limiting the promotion and popularization of epoxy resin-based carbon fiber composites

Embodiment 1

[0044]As shown in Figure 2, the present invention is used in the manufacture of epoxy resin-based carbon fiber composite material bicycle rims. Because the rim is made of epoxy resin-based carbon fiber composite material, to prevent the high temperature generated during braking from deforming the rim, a ceramic coating can be provided on the braking surface to insulate heat and increase wear resistance.

[0045] Get the finished product of bicycle rim 1, set stop body 2 on the inner side of rim braking surface 10, its purpose is to avoid deformation of braking surface 10 under the effect of pressure and heat generated during spraying, and keep product characteristics. After being prepared, the braking surface 10 is subjected to sandblasting and roughening treatment, the size of the sand particles is 40 meshes, and then an arc spraying equipment is used to uniformly spray a layer of zinc-aluminum alloy metal bottom layer 11, the thickness of the metal bottom layer is 0.05mm, and...

Embodiment 2

[0047] As shown in Figures 3 and 4, similar to the embodiment, the present invention is used in the manufacture of epoxy resin-based carbon fiber composite disc brake discs.

[0048] Take the finished disc brake disc, first set a stop body on one side of the disc brake disc 3, and carry out sandblasting and roughening treatment on the braking surface 30 on the other side. Al-Mg alloy metal bottom layer 31, the thickness of the metal bottom layer is 0.25mm, and finally spray ceramic powder with plasma spraying equipment, the composition of ceramic powder is alumina, the powder diameter is 5 microns, when spraying, the voltage of the arc is 120V, and the current is 700A , the distance between the nozzle of the spray gun and the surface of the substrate is 100mm, and the ceramic coating 32 with a thickness of 0.5mm is uniformly sprayed.

Description

Technical field: [0001] The invention relates to the technical field of protecting the surface of civil industrial products using epoxy resin-based carbon fiber materials as matrix materials, including sports equipment and sports equipment, and particularly refers to a method of spraying ceramics on the surface of epoxy resin-based carbon fiber composite products. craft. Background technique: [0002] In the big family of composite materials, fiber reinforced materials have always been the focus of attention. Since the advent of FRP composited with glass fiber and organic resin, carbon fiber, ceramic fiber and boron fiber reinforced composite materials have been successfully developed, and their properties have been continuously improved, making the field of composite materials full of vitality. [0003] Carbon fiber is mainly a special fiber composed of carbon elements, and its carbon content varies with different types, generally above 90%. Carbon fiber is made of man-ma...
