Title:
FRP CYLINDRICAL BODY
Document Type and Number:
Japanese Patent JP3278985
Kind Code:
B2
Abstract:
PURPOSE: To provide a cylindrical body, excellent in the balance of torsional characteristics, such as torsional strength, torsional elasticity and the like, and bending characteristics, such as bending elasticity and the like, as well as compressive strength in the radial direction of the same.
CONSTITUTION: A first carbon fiber layer of ±θ1° (10≤θ1≤80) is arranged at both sides of the center of lamination while pinching the center of lamination so as to obtain mirror-like symmetry with respect to the center of lamination, then, second carbon fiber layers of θ2° (85≤θ2≤95) are arranged at the outside of the first carbon fiber layers and third carbon fiber layers of θ3° (-5≤θ3≤5) are arranged at the outside of the second carbon fiber layers to produce a FRP cylindrical body.
