TUBULAR BODY MADE OF FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP2000263653
Kind Code:
A
Abstract:
To provide a tubular body made of fiber-reinforced composite material being lightweight and having high excellent distortional strength.
The tubular body made of fiber-reinforced composite material is formed such that low elastic modulus carbon fiber having a tensile elastic modulus of 5-160 GPa, a compression rupture strain of 1-5%, and a density of fiber of 1.5-1.9 g/cm3 is arranged at an orientation angle of +35 to +55° and -35 to -55° with respect to the longitudinal axial direction of the tubular body.
