Title:
HYBRID CARBON FIBER SPUN YARN AND HYBRID CARBON FIBER SPUN YARN FABRIC USING SAME
Document Type and Number:
WIPO Patent Application WO/2006/090643
Kind Code:
A1
Abstract:
Disclosed is a hybrid carbon fiber spun yarn comprising a core portion mainly containing carbon fibers and a sheath portion mainly containing carbon fibers and covering the outer surface of the core portion. Not less than 20% by mass of the fibers constituting the core portion are long-fiber-length carbon fibers having a fiber length of not less than 500 mm, and not less than 80% by mass of the fibers constituting the sheath portion are short-fiber-length carbon fibers having a fiber length of less than 500 mm. The mass ratio between the long-fiber-length carbon fibers and the short-fiber-length carbon fibers (long-fiber-length carbon fibers : short-fiber-length carbon fibers) is from 20:80 to 80:20.
