Kind Code:
A1
Abstract:
Disclosed is a carbon fiber wound tape wherein carbon fiber tape formed from a complex that includes a carbon fiber and an aromatic polyamide resin or an aliphatic polyamide resin is wound around a cylindrical core material. The width (W) of the carbon fiber tape found using the formula (I) is between 5-100 mm and the minimum diameter (D) of the cylindrical core material around which the carbon fiber tape of said width (W) between 5-100 mm is wound is found using the formula (II). (I) 0.2×10-3×N≦W≦2×10-3×N (wherein N is the number of carbon fibers that make up the carbon fiber); (II) 4.5×F×t≦D≦50×F×t (wherein F is the carbon fiber amount, in the range of 20%-60% by mass, and t is thickness of the carbon fiber tape, in the range of 0.1-0.5 mm.)
