Tubular body for sports products |
| abstract |
(57) [Summary] [Problem] Tubular for sports products excellent in various strength characteristics such as rigidity, torsion strength, crushing strength and impact resistance without sacrificing heat resistance, etc. Provide the body. A vibration period difference T of a pendulum measured by a free pendulum vibration method of a rigid pendulum is expressed by the following equations (1) and (2). Tensile modulus YM obtained by firing an acrylic precursor for carbon fiber to which a silicone oil agent satisfying A sports product tubular body using (GPa) and carbon fiber having a nitrogen content NC (%) satisfying the following formulas (3) and (4). 0.03 ≦ T ≦ 0.4 (1) T = T30−T180 (2) T30: Vibration period at 30 ° C. (second) T180: Vibration period after heat treatment at 180 ° C. for 10 minutes (second) NC ≧ − 30.102 × LOG (YM) +77.785 (3) 200 ≦ YM ≦ 340 (4) |
