Abstract
Carbon/carbon-silicon carbide (C/C-SiC) composites, as a promising material for brake disks, have been widely concerned by researchers. In this work, the C/C-SiC composite that has potential applications in future advanced braking systems has been fabricated by combining low temperature compression molding (LTCM) and liquid silicon infiltration (LSI). The effects of the carbon fibers (Cf) dispersion and LSI on the properties of the C/C-SiC composite have been investigated. The results demonstrate that the as-prepared composite with a high density of 2.3 g cm-3 and low open porosity of 6% exhibits a high bending strength of 120 MPa and compressive strength of 153 MPa. Moreover, it displays a "False plasticity" phenomenon, indicating the excellent mechanical properties. Additionally, a stable friction coefficient of 0.33 has been also obtained, which demonstrates that the chattering phenomenon can be effectively controlled to obtain comfortable driving conditions during the brake process.
