Description

Technical Field

[0001] This utility model relates to the technical field of automotive braking, specifically to a structure of environmentally friendly carbon fiber friction material for automotive braking. Background Technology

[0002] Brake friction material is a key material used in braking systems. It generates friction through contact with the brake disc or brake drum, thereby achieving the purpose of decelerating or stopping the vehicle. Brake friction material is usually composed of a mixture of various materials, including organic materials, inorganic materials, and metals. Different combinations of these materials can produce different friction properties and wear characteristics.

[0003] With increasing environmental awareness and intensified energy consumption, traditional friction materials can no longer meet the needs of modern transportation. Traditional friction materials are usually composed of materials such as asbestos and rubber. These materials generate a large amount of harmful substances during manufacturing and use, and are also heavy, causing serious harm to the environment and human health. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figures 1-5 This utility model discloses a structure of environmentally friendly carbon fiber friction material for automotive brakes, comprising a carbon fiber friction layer 1, a fiber edging layer 2, an adhesive layer 3, and a reinforcing layer 4, wherein:

[0026] The carbon fiber friction layer 1 includes a carbon fiber mesh 11, and the carbon fiber mesh 11 is filled with a filler layer 6.

[0027] The fiber edging layer 2 includes a fiber cloth sleeve 21 that wraps the carbon fiber mesh 11, and multiple carbon fiber friction layers 1 are stacked in the fiber cloth sleeve 21.

[0028] The adhesive layer 3 is used to bond the fiber friction layer to the fiber edge layer 2 and the adjacent carbon fiber friction layer 1.

[0029] Furthermore, the carbon fiber mesh 11 uses 3k carbon fiber, which has good friction properties. The filling layer 6 includes copper-based powder filled in the mesh of the carbon fiber mesh 11. The copper-based powder has good friction properties and environmental protection characteristics.

[0030] Please refer to the appendix. Figure 2 It also includes a heat-conducting wire 5, which comprises multiple aluminum wires that longitudinally pass through the multilayer carbon fiber friction layer 1. Aluminum is a lightweight thermally conductive metal material with high thermal conductivity. The aluminum wires pass through the mesh of the carbon fiber mesh 11 and are wrapped by the filling layer 6.

[0031] Furthermore, the reinforcing layer 4 is wrapped with multiple reinforcing lines. Multiple carbon fiber lines pass through the fiber cloth sleeve 21 and extend to the outside of the fiber cloth sleeve 21 around the carbon fiber mesh 11. The ends of the carbon fiber lines passing through the fiber cloth sleeve 21 are fixed by reinforcing lines. The fiber cloth sleeve 21 is woven from ceramic fibers, and the reinforcing lines are twisted from ceramic fibers. Ceramic fibers have high heat resistance and good friction performance, and can maintain a stable coefficient of friction at high temperatures.

[0032] Furthermore, the adhesive layer 3 is disposed between the carbon fiber mesh 11 of adjacent carbon fiber friction layers 1 and on the inner wall of the fiber cloth sleeve 21. The carbon fiber mesh 11 is in contact with the inner wall of the fiber cloth sleeve 21. The adhesive layer 3 is a polyurethane adhesive, which has excellent wear resistance and impact resistance. When mixed with fibers and other fillers, it improves the friction performance.

[0033] The operation process and principle of this utility model are as follows: The carbon fiber friction layer 1 is stacked and fixed inside the fiber cloth sleeve 21. During friction braking, the carbon fiber mesh 11 on the carbon fiber friction layer 1 rubs against the copper-based powder. The heat generated during the friction braking process is transferred and discharged through the aluminum wire. At the same time, the fiber cloth sleeve 21 includes the carbon fiber mesh 11 to keep the carbon fiber mesh 11 stable. With the reinforcement wire that fixes the carbon fiber wire at the outer end of the carbon fiber mesh 11, the carbon fiber mesh 11 is further fixed. When the friction material is worn after long-term use, the outermost carbon fiber friction layer 1 is worn, and the next layer of carbon fiber friction layer 1 is exposed to continue friction braking.
