Title:
PITCH-BASED CARBON FIBER WEB, PITCH-BASED CARBON STAPLE FIBER, AND PROCESSES FOR PRODUCTION OF SAME
Document Type and Number:
WIPO Patent Application WO/2010/084856
Kind Code:
A1
Abstract:
Provided is a pitch-based carbon fiber which has a smaller mean –fiber-diameter distribution and more excellent mechanical strengths as compared with those of a pitch-based carbon fiber produced by melt blowing. Disclosed is a pitch-based carbon fiber web composed of pitch-based carbon fibers which have a mean fiber diameter of 5 to 20μm, a CV value of mean fiber diameter of 3 to 8%, a tensile modulus of 150 to 1000GPa, and a tensile strength of 2.5 to 5GPa. The carbon fiber web can be suitably produced by spinning which is accompanied with drawing by air jet parallel to the direction of the spinning.
