摘要: PROBLEM TO BE SOLVED: To provide a strand of carbon fibers usable in pultrusion, etc., excellent adhesion to matrix resin, and molding property composite material an industrial scale by taking into consideration for prevention troubles molding. SOLUTION: The sized has 25-70 flatness ratio traveling (ratio width/thickness the strand), after subjecting roller processing at 5 m/min, under 200 gf tension 100-160% coefficient variation spreading which is width m/min 2 kgf prescribed traveling.
