Abstract
As the increasing requirements for occupant safety, this project aims to study brake performance of disc brake. It proposed a new design for normal disc brake: restructure the disc and reselect frictional material. The new disc brake subvert traditional style: permits to remove original calipers and adds another two pads facing to inner surface of disc, which looks like a squirrel cage or a hollowed drum, the brake cylinder becomes two-way insides the disc and provides brake pressure for both inner pads to compress disc. These differences contributes to a larger friction area. Besides, combined with nanomaterials, the novel disc brake is advanced in heating fade resistance and corrosion resistance or what else. Make use of CAD and CAM, our project turn from theory to practice. Firstly, we will give a brief introduction about disc brake and nanomaterials. Secondly, we explains how to enhance the brake performance for the new disc brake with nanomaterials-present a method to compare inherent properties of different nanomaterials and select optimum kinds.Then, according to the structure of disc brake and basic parameter, we do some calculation use CATIA software to built the disc brake model and do analysis in ANSYS CFX. Draw from calculation and analysis, it is proved to make profits.
Key words : disc brake, brake performance, nanomaterials

The project focus on the issue of brake performance of disc brake, it modifies the normal style with redesigned structure and altered frictional material. This new brake (show in fig.2)permits to remove original calipers and adds another two pads facing to inner surface
