LONG STRUCTURAL MEMBER AND STRUCTURAL MEMBER COMPLEX USING SAME

摘要

Provided are a long structural member and a structural member complex that comprise a fiber-reinforced resin having a simple reinforced structure, suppressing increase in molded article weight, and exhibiting high mechanical properties. The long structural member has a perpendicular cross-section formed in a U shape, has two of the corners on the inside of the U-shaped section reinforced by the fiber-reinforced resin, and has a triangular cross-section for each of the cross-sections of the two corners inside the reinforced U-shaped section, that fulfills the following formulas. 0.05≦W/W0≦0.15 and 0.15≦H/H0≦0.36 (W0: length of the outer surface of a floor section of the U-shaped section in a cross-section perpendicular to the axis of the long structural member; W: length of an inner surface of a floor section of the U-shaped section, for the corners on the inside of the reinforced U-shaped section of the cross-section perpendicular to the axis of the long structural member; H0: length of the outer surface of an upright surface section of the U-shaped section of the cross-section perpendicular to the axis of the long structural member; and H: the length of an inner surface of the upright surface section of the U-shaped section, for the corners on the inside of the reinforced U-shaped section of the cross-section perpendicular to the axis of the long structural member.

1: A long structural member formed to have a U-shaped longitudinal cross-section and formed such that two corners inside the U-shaped portion are reinforced by fiber reinforcement resin and a cross-section of each of two corners inside the reinforced U-shaped portion is a triangular cross-section satisfying the following equations:
0.05≦W/W0≦0.15 0.15≦H/H0≦0.36, wherein W0 indicates an outer face length of a bottom face portion of the U-shaped portion of the longitudinal cross-section, W indicates an inner face length of the bottom face portion of the U-shaped portion of the inner corner of the reinforced U-shaped portion of the longitudinal cross-section, H0 indicates an outer face length of the upright face portion of the U-shaped portion of the longitudinal cross-section, and H indicates an inner face length of the upright face portion of the U-shaped portion of the inner corner of the reinforced U-shaped portion of the longitudinal cross-section.
