SURFACE-MODIFIED FIBER AND PROCESS FOR PRODUCING SAME

Title:

SURFACE-MODIFIED FIBER AND PROCESS FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2010/073915

Kind Code:

A1

Abstract:

A high-strength surface-modified fiber having such excellent bondability that the excellent mechanical properties of the reinforcing fiber can be reflected in the material properties of FRPs or the like, and a process for producing the fiber. The surface-modified fiber has a strength of 8 cN/dtex or higher, and is characterized in that when the fiber surface is examined with an atomic force microscope, 20 or more crack-like recesses extending over 0.1 µm or more in the fiber minor-axis direction and having a depth of 10-100 nm are present in an area with dimensions of 4 µm (fiber major-axis direction) by 2 µm (fiber minor-axis direction) within the field of view. The process for producing the fiber is characterized by treating the surface of a fiber by bombardment with ion beams.
