Tubular article

管状体

Abstract

<P>PROBLEM TO BE SOLVED: To enlarge the degree of freedom of designing a tubular article and facilitate rigid design. <P>SOLUTION: In a tubular article obtained by baking two or more layers of reinforcing fiber prepregs, two or more reinforcing fibers are plain-woven in one direction and a direction perpendicular to the direction of axes of the reinforcing fibers. The tubular article has a biaxial plain-woven fiber layer 4 composed of biaxial plain-woven prepregs impregnated with a thermoplastic resin and laminated together and a quadruple laminated fiber layer 5 composed of quadruple laminated prepregs laminated together, and the quadruple laminated fiber layer 5 is formed by arranging two or more fiber rows formed by arranging two or more reinforcing fibers in parallel, in one direction of the axes of the fiber rows and in a direction perpendicular to the direction of the axes of the fiber rows, in a direction intersecting obliquely with the axial direction of the resultant biaxial reinforcing fiber and in a direction intersecting with the axial direction of the resultant triaxial direction, laminating the fiber rows, with a clearance formed between fiber rows in the same axial direction, in the direction of the thickness of the tubular article and impregnating the resultant body with a thermoplastic resin to obtain a quadruple laminated prepregs and laminating the quadruple laminated prepregs. <P>COPYRIGHT: (C)2011,JPO&INPIT
【課題】設計自由度の拡大及び剛性設計の容易化。 【解決手段】複数層の強化繊維プリプレグを焼成して得られる管状体において、複数の強化繊維を、該強化繊維の軸方向が一方向と該一方向と直交する方向として平織りするとともに、熱硬化性樹脂を含浸してなる二軸平織プリプレグが積層された二軸平織繊維層4と、複数の強化繊維を並列させてなる複数の繊維列を、該繊維列の軸方向が、一方向と、該一方向と直交する方向と、これら2軸方向の強化繊維の軸方向に対して斜めに交差する方向と、これら3軸方向の強化繊維の軸方向に対して交差する方向とに配置するとともに、軸方向を同一とする各繊維列間に隙間を空けて管状体の厚み方向に積層し、かつ熱硬化性樹脂を含浸してなる四軸積層プリプレグが積層された四軸積層繊維層5と、を備えていることを特徴とする。 【選択図】図2
