An object of the present invention is to manufacture a lightweight and strong composite of a magnesium alloy and a CFRP, by strongly bonding the magnesium alloy and the CFRP using an epoxy adhesive. The magnesium alloy having specific ultra-fine irregularities is compatible with an epoxy resin adhesive and exhibits thus strong adhesion. A magnesium alloy composite plate material 23 , in which magnesium alloy plates 25 and a CFRP 24 are integrated by exploiting this technique, can be used in ordinary assembly structures with other metal members 28 and bolts 27 . The magnesium alloy plates 25 can withstand strong local forces, and hence the CFRP 24 is not damaged. As a result, the composite is effective for applications in, for instance, casings, bodies and parts in mobile equipment such as automobiles or in mobile devices, where lightweightness, toughness and ease of assembly are required. |
