Abstract

The invention provides a copper alloy based sepiolite, ferric oxide, vermiculite and barium ferric oxide 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 copper alloy as the matrix and the sepiolite and ferric oxide compounds and the vermiculite and barium ferric oxide compounds are distributed on the matrix. The two kinds of compounds account for 40-50% of the composite material by volume. The copper alloy matrix comprises the following chemical components in percentage by weight: 3-5% of Al, 0.05-0.1% of Te, 0.05-0.1% of Co, 0.005-0.01% of Pr and the balance Cu.
