This study deals with the development of new friction materials by incorporating Miscanthus fiber (5, 10, and 15 weight %, noted Mat1, Mat2, and Mat3, respectively). The friction materials were tested for their physical, mechanical, and microstructural properties as per international standard. The performance analysis was carried out using Chase friction test rig. Results revealed that the biomass is beneficial with good fade, wear resistance, and recovery characteristics, with the same trend of other natural fibers. Therefore, this natural ingredient proved to be useful in the development of brake friction material.
Purpose
This paper aims to develop of magnetic field controlled friction braking technology, a novel brake friction material with magnetic was designed and prepared in this paper.
Design/methodology/approach
The permalloy, a soft magnetic material, was selected as an additive to design and prepare the magnetic brake material. The friction, wear performance and permeability of each brake pads were investigated by experiments. By choosing the performance of friction coefficient fluctuation, friction coefficient deviation and mean wear rate as optimization parameters, the formulation of the magnetic friction material was optimized based on Fuzzy theory by using analytic hierarchy process methods and SPSS software.
Findings
The results showed that the developed soft magnetic friction material has not only superior friction coefficient, permeability and inferior wear rate but also good physical and mechanical properties.
Originality/value
Permalloy powder was added to the formulation of friction material to achieve a new functional friction material with high magnetic permeability. It is believed that this research will be of great theoretical and practical significance to develop both new brake materials and active control technology of the braking process in the future.
