Claim 5:
6. A method for manufacturing a heterogeneous composite material comprising:
installing a frame in a first cavity formed in a mold;
injecting a first material into an outer space of the frame of the first cavity;
removing the frame to form a second cavity including a boundary surface in contact with the first material;
injecting a second material different from the first material into the second cavity; and
simultaneously compressing the first material and the second material to generate a heterogeneous composite material,
wherein the boundary surface exists in a circular shape with a predetermined radius with respect to a central axis of the frame,
wherein at least a portion of the first material and at least a portion of the second material are disposed on both sides of the boundary surface in a state in contact with each other at the boundary surface.
