Document Type and Number:
WIPO Patent Application WO/2022/201960
Kind Code:
A1
Abstract:
A fiber-reinforced-resin tubular body (1) used as a structural material of a vehicle includes corners (4) extending along the axis of the tubular body (1) at the outer peripheral surface thereof. The tubular body (1) is a tubular laminated body in which a woven fabric layer (12) formed by laminating multiple woven fabric materials and multiple one-directional material layers (11, 13) are laminated. Each of the woven fabric materials includes a woven fabric of reinforcing fibers and resin impregnated through the woven fabric. Each of the one-directional material layers (11, 13) includes reinforcing fibers oriented in one direction and resin impregnated through the reinforcing fibers. The reinforcing fibers of the one-directional material layers (11, 13) are oriented along the axis of the tubular laminated body. The multiple one-directional material layers (11, 13) include the outer one-directional material layer (13) laminated on the outer peripheral surface of the woven fabric layer (12) and the inner one-directional material layer (11) laminated on the inner peripheral surface of the woven fabric layer.
