; 1 Introduction C/C-SiC, carbon fiber reinforced carbon and SiC matrix composite, has been developed to use as braking material since the end of 1990s[1-4]. It is promising candidate for advanced braking system [2]. In comparison with grey cast iron or carbon/carbon, C/C-SiC braking composite exhibits high coefficient......

to the formation of Al4C3 and Si[10]. Fig.3 shows the XRD result of the 10% SiCp/Al-2.5Mg composite. It can be seen that only Al, SiC, MgO and MgAl2O4 exist in the prepared composite and no reflections corresponding to Al4C3 are observed. Fig.4 shows the TEM micrograph of the 10% SiCp/Al-2.5Mg composite and diffraction pattern of MgAl2O4. It testifies that MgAl2O4 layer appears on SiCp surface. The same......

and low cost was used to fabricate microscale fibers [9-10]. Among these microscale fibers, most of them were single phase materials [10]. Two and multiphase composite functional materials stimulated interests as these composite materials potentially combine the component characteristics to meet various requirements technologically. In particular, the multiferroic composite Q1D materials......
