Abstract
Disclosed is a preparation method for a composite which comprises the following steps: (a) preparing unit metal pieces comprising two or more types of different metals; (b) circumferentially arranging the two or more types of unit metal pieces in a mold comprising upper and lower dies; (c) applying compressive stress to the loaded metal pieces using the upper and lower dies; and (d) rotating the upper and lower dies in one or two directions to apply torque in the pressed state.
Claims5
A method of preparing a laminate composite, comprising:
- (a) preparing two types of unit metal specimens comprising different metals;
- (b) circumferentially arranging the two types of unit metal specimens in a mold having upper and lower dies, wherein the two types of unit metal specimens are circumferentially arranged in an A-B-A-B pattern;
- (c) applying compressive stress to the loaded metal specimens using the upper and lower dies;
- and
- (d) rotating either or both of the upper and lower dies to apply torque to the metal specimens which are pressed and forming the laminate composite having a spiral laminate structure in a thickness direction.
