Title:
繊維強化樹脂管状体
Document Type and Number:
Japanese Patent JP7024959
Kind Code:
B2
Abstract:
To provide a fiber reinforced resin tubular body of which reinforced fiber forming a flexure planned area is hardly broken and the flexure planned area is hardly buckled when flexure processing is conducted at a state that a resin at the flexure planned area can be plastically deformed by heating.SOLUTION: A fiber reinforced thermoplastic resin forming a fiber reinforced resin tubular body 1 is formed by a continuous carbon fiber S and a polyamide resin, and has an arrangement structure of the continuous carbon fiber so that orientation angle θ1 to an axis line G of the continuous carbon fiber S forming a flexure planned area VE is larger than orientation angle θ2 to the axis line G of the continuous carbon fiber S respectively forming areas E1, E2 which are other than the flexure planned area.SELECTED DRAWING: Figure 2
