Title:
中空筒体、曲げ部を有する筒状成形体、及び曲げ部を有する筒状成形体の製造方法
Document Type and Number:
Japanese Patent JP6804240
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cylindrical molding having an excellent external appearance shape by bending a hollow cylindrical body made of a fiber-reinforced thermoplastic resin.SOLUTION: A hollow cylindrical body composed of a fiber-reinforced thermoplastic resin and used by bending a part thereof, includes a first hollow cylindrical part 11 and a second hollow cylindrical part 12. First reinforcement fibers 31 intersecting with a circumferential direction of the first hollow cylindrical part 11 are oriented in the first hollow cylindrical part 11, while second reinforcement fibers 32 intersecting with a circumferential direction of the second hollow cylindrical part 12 are oriented in the second hollow cylindrical part 12. An intersection angle of the second reinforcement fibers 32 with respect to a central line of the second hollow cylindrical part 12 is larger than an intersection angle of the first reinforcement fibers 31 with resect to a central line of the first hollow cylindrical part 11.SELECTED DRAWING: Figure 2
