Title
Mechanical Properties of Helical Fiber Reinforced Aluminum Matrix composite
김석윤Suk Yoon Kim, 현창용Chang Yong Hyun
Abstract
Aluminum-base composites reinforced with high carbon steel and stainless steel fibers were prepared by a liquid phase casting method. The fibers were helical type with various helical angles and they were coated with nickel and copper, respectively. The mechanical properties of these composities and interfacial phenomena between fibers and matrix were investigated. A thin film of intermetallic compound produced on the fiber surface improves the wettability between fibers and matrix. The aluminum-helical fiber composite having a helical angle of 65 degrees shows a better combination of strength and ductility. The ultimate tensile strength of composite become greater in the order, uncoated fiber, nickel coated fiber and copper coated fiber.
