Problems solved by technology

However, there is a problem when using carbon fiber that, due to its low melting point, a sharp decrease in braking force due to an excessive increase in friction temperature occurs, and the price is high
[0005] However, this is not ideal for racing friction materials that require high braking and fading characteristics

Embodiment Construction

[0013] Next, the present invention will be described in detail.

[0014] In the composition of the steel friction material for racing car of the present invention, a single steel fiber base material or a mixture with a mineral fiber base material is used as the fiber base material, and no carbon fiber is used.

[0015] In particular, the fibrous raw material having the largest weight ratio in the composition of the friction material of the present invention is steel fiber.

[0016] The content of the fibrous base material mainly composed of steel fibers is 25-50% by weight in the composition of the overall friction material. If the content thereof is less than 25% by weight in the overall composition, there is a problem that the braking force and the strength of the friction material are lowered. If it exceeds 50% by weight, there is a problem of increased brake noise.

[0017] The composition of the friction material of the present invention contains both the aforementioned...

Abstract

The invention provides a steel friction material composition for racing, which contains 25-50% by weight of a single steel fiber base material or a mixture with a mineral fiber base material; 5-20% by weight of Modified phenol resin; 15-30% by weight of antimony or graphite raw material as solid lubricant; 10-30% by weight of abrasive containing silicon carbide; and 10-25% by weight of filler containing sponge iron powder. This can prevent the occurrence of a decrease in the internal strength of the friction material, a fading phenomenon in which the braking force decreases sharply due to an excessive increase in friction temperature due to a relatively low melting point, a decrease in braking stability, and Brake noise phenomenon.

Description

technical field [0001] The present invention relates to a steel friction material for a racing car, more specifically, to a composition of a steel substrate friction material constituting a racing brake pad. Background technique [0002] Unlike brake friction materials for passenger cars, brake friction materials installed on racing cars require: braking stability with uniform friction performance even under high braking force and changing braking conditions; Thermal conductivity in which the frictional heat generated at the friction interface of the friction material is easily transferred to the outside; heat resistance and fading resistance in which the friction force rarely changes due to friction temperature rise; and initial fading resistance in which the reduction in braking force at the initial stage of installation is small . [0003] Usually, the composition of the brake friction material includes: fiber base material; bonding material and filler; additives such as...
