Title:
COMPOSITE MATERIAL BRAKE ROTOR, PREPARATION METHOD THEREFOR, AND FRICTION STIR TOOL
Document Type and Number:
WIPO Patent Application WO/2022/063099
Kind Code:
A1
Abstract:
A composite material brake rotor, a preparation method therefor, and a friction stir tool. The composite material brake rotor comprises: an aluminum alloy substrate layer (110) and an aluminum-based composite layer (120), the aluminum alloy substrate layer (110) and the aluminum-based composite layer (120) are bonded together by a metallurgical bonding means, a transition layer (130) is produced at an interface where the aluminum alloy substrate layer (110) and the aluminum-based composite layer (120) are bonded together, and a reinforcement structure connecting the aluminum alloy substrate layer (110) and the aluminum-based composite layer (120) are formed in the transition layer (130).
