Abstract
Disclosed are a micro fiber and a method of manufacturing the micro fiber are proposed. The micro fiber may be manufactured by controlling thickness and Young's modulus thereof using hollow fiber.
Claims17
A method of manufacturing a micro fiber, the method comprising:
- preparing a hollow fiber;
- injecting a liquid metal into the hollow fiber;
- forming a composite fiber by crystallizing the liquid metal to form a metal wire thereby obtain composite fiber;
- drawing the composite fiber;
- and
- removing the hollow fiber from the composite fiber,
- wherein the composite fiber comprises a core part including the metal wire, and a sheath part including the hollow fiber.
