Title:
FISHING ROD
Document Type and Number:
Japanese Patent JP2573923
Kind Code:
B2
Abstract:
PURPOSE: To obtain a fishing rod securing a good tensile flexural strength and simultaneously having a sufficient collapse strength by employing PAN carbon fibers in a reinforcing fiber layer having the fiber direction in the axial direction of the fishing rod and further employing pitch carbon fibers in a reinforcing layer having the fiber direction in the circumferential direction of the fishing rod.
CONSTITUTION: Reinforcing fiber layers 2, 3 comprising pitch carbon fibers having the fiber direction in the circumferential direction of the fishing rod are integrally wound on the inner and outer sides or either one side of a reinforcing layer 1 comprising PAN carbon fibers having the fiber direction in the axial direction of the fishing rod to obtain the fishing rod having a large tensile strength, a large flexural strength, a high elastic modulus and a small elongation and prevented in its compression collapse and deformation.
