Document Type and Number:
WIPO Patent Application WO/1997/043115
Kind Code:
A1
Abstract:
A large-sized columnar body which is formed out of a fiber-reinforced plastic comprising continuous fibers and a resin, and which has three layers (A, B, C) laid in the mentioned order, characterized in that the reinforcing fiber in the B layer is carbon fiber arranged in the lengthwise direction of the columnar body, the fiber in the A layer and C layer being carbon fiber or/and glass fiber arranged at U50 to U70 degrees with respect to the lengthwise direction of the columnar body. This large-sized columnar body of FRP has a high compressive strength, so that the weight thereof can reduced to below that of a conventional large-sized columnar body.
