The relations between composition, electronic structure, chemical bond and property of composites of Ti3AlC2/TiB2, Ti2AlC/TiB2 and related single phases of Ti3AlC2, Ti2AlCas well as TiB2 are studied by the first principle methods. There are strong ionic and covalent interactions among the interfaces of the composites. The interactions among the interfaces, the whole ionic and covalent bond of Ti3AlC2/TiB2 are stronger than those of Ti2AlC/TiB2. The results are consistent with the result of experiment that the mechanics property of Ti3AlC2/TiB2 is better than that of Ti2AlC/TiB2.
