On Manufacturing of Long Stainless Steel Fiber with Fin by Multi-Tooth Tool and Mechanical Properties of the Fiber

Abstract

Metal fiber manufactured by the methods nowadays available almost could not meet the new requirements any more due to the increasing demands for its properties as it is used more and more widely. In this paper, cutting by multi-tooth tool, a new method, which can bifurcate chip and simultaneously get many pieces of long stainless steel fiber with high tensile strength, good tenacity and corresponding diameter within 100μm even 50μm, is proposed. Tiny fins which induce crystal growth as nucleation in composites can form regularly at the edge of fiber under certain conditions. The fiber possesses unique advantages if it is used to filled, reinforced and porous materials because of its rough surface, fins, high tensile strength and good tenacity.
