Fiber reinforced metal composite and application thereof

A preparation method for the shell of fiber reinforced magnesium alloy luggage case, characterized in that the fiber reinforced magnesium alloy composite used for the case shell is a two-layered structure and the preparation method includes steps of:

• S1, cutting a magnesium alloy sheet into a desired shape and then surface-treating the cut magnesium alloy sheet so as to form a protective layer on the surface of the magnesium alloy;
• S2, processing the surface-treated magnesium alloy sheet into a box shape by hot press forming or bending forming;
• S3, applying evenly the room-temperature curing adhesive to the inner surface of the magnesium alloy case shell obtained in step S2, further bonding a fiber material to the inner surface of the magnesium alloy case shell coated with the adhesive, and rolling the surface of the fiber layer with a roller so that the fiber layer is in close contact with the magnesium alloy case shell;
• S4, placing the composite case obtained in step S3 in a mold and then placing in a pressure curing device with a curing temperature of 20˜30° C., a curing pressure of 0.2˜1MPa, and a curing time of 10˜30 min.
• S5, placing the composite case shell completed in step S4 at 20˜30° C. for 1 to 5 hours to completely cure the composite of case shell.
