Problems solved by technology

Among them, particle, fiber and whisker reinforced phase are the most common reinforcements, but they form a discontinuous interface with the metal composite, and the reinforced phase is easy to fall off during the braking process, which greatly reduces the performance of the composite material.
Three-dimensional mesh ceramics reinforced metal matrix composites are greatly limited because the closed-pore problem of mesh ceramics cannot be effectively solved, and it is difficult to cast them into defect-free products.

Abstract

The invention relates to a power vehicle brake disc and its preparation method. The method of the invention mainly includes the preparation of three-dimensional mesh material, the preparation of ceramic slurry, the preparation of binder, the preparation of three-dimensional ceramic skeleton, the preparation of light alloy and the preparation of light composite Brake disc preparation; the lightweight composite brake disc made according to the above method mainly includes: a body integrally formed by light alloys such as aluminum, aluminum magnesium or titanium, and two three-dimensional ceramics with porous rings. The center of the body has an axis, and the two sides of the body have friction surfaces surrounding the axis. The two friction surfaces are each equipped with a three-dimensional ceramic skeleton molded together with the body, and the pores of the three-dimensional ceramic skeleton are filled with Lightweight alloy with continuous composite strength, high efficiency and high quality to manufacture lightweight composite brake discs.

Description

technical field [0001] The invention relates to a power vehicle brake disc and a preparation method thereof, belonging to the technical field of vehicle friction brake components, in particular a lightweight composite power vehicle brake disc with continuous composite strength, high efficiency and high quality and a preparation method thereof. Background technique [0002] Today, fuel and environmental protection regulations around the world are becoming increasingly stringent. In order to improve fuel efficiency and reduce carbon dioxide emissions, automobiles must continue to be lightweight. Car lightweight has always been a hot topic. The concept of car lightweight is to reduce the overall mass of the car as much as possible while ensuring the strength, stiffness, modal and safety functions of the car, so as to improve the power and handling of the car Sex, reduce fuel consumption, reduce exhaust pollution. In order to meet the needs of lightweight vehicles, the applicat...
