Aluminium matrix composite brake discs
CRRC QISHUYAN INSTITUTE CO., LTD. (Guozhong Jin) / CSIRO (Daniel Liang)
This project involved the manufacture and testing of a new material for brake discs. Made of ceramic and metal composite, these brake discs are more wear resistant and a better conductor of heat. The material was developed based on the solid-state-forming CSIRO technologies studied in a lab environment, and then scaled up for manufacture. CRRC has large scale testing rig in China to test the material under the relevant rail working environments.
31 January 2018 to 31 January 2020
Total contracted budget (including in-kind)
- The team at CSIRO successfully applied the solid-state forming technology to the rail brake disc application and produced full size brake discs made from aluminium ceramic composite material through the novel material processing.
- Specifications and operational instructions were developed for preparation of materials and processes for preparation of 1:1 scale brake disc.
- The brake discs met requirements for essential properties such as mechanical strength, wear rate and heat dissipation, enabling the composite brake disc to enter a certification and train trial process at CRRC prior to production commencing.
