Abstract

The invention provides a zinc alloys, sepiolite-ferric oxide and vermiculite-barium ferrate composite material and a preparation method thereof. The composite material has high absorbing property and excellent damping property. The preparation method is simple in process, low in production cost and suitable for industrialized production. The composite material takes the zinc alloys as the matrices and the sepiolite-ferric oxide and vermiculite-barium ferrate compounds and titanium fibers are distributed on the matrices. The zinc alloys, the sepiolite-ferric oxide and the vermiculite-barium ferrate account for 40-50% of the composite material by volume. The titanium fibers comprise the following components in percentage by weight: 0.2-0.4% of V, 0.003-0.09% of Pr and the balance Ti. The zinc alloy matrices comprise the following chemical components in percentage by weight: 13-18% of Al, 0.05-0.1% of Te, 0.05-0.1% of Co, 0.005-0.01% of Pr and the balance Zn.
