A composite tapered tubular assembly includes a composite tapered tube extending between a first end and a second end and tapered so as to have a smaller radius R1 at the first end than a radius R2 at the second end. The assembly also includes a first internal annular wedge that is in contact with an inner surface of the tube at said first end and a first external annular wedge in contact with the outer surface of the tube at said first end. The assembly further includes a first nut provided at said first end that is configured to be connected to said first internal wedge and a second external annular wedge provided on an outer surface of the tube and a second internal annular wedge in contact with the inner surface of said composite tube at said second end, and a second nut connected to an internal surface.

Energy absorption at the time of load input is improved with high mass efficiency. A hollow member includes: a hollow metal member having a bending induction portion in a portion thereof in a longitudinal direction; and a resin material which is disposed in close contact with the metal member on both sides of the bending induction portion in the longitudinal direction, and is disposed in at least a part of a range of less than ⅚ of a cross-sectional height of the metal member from an end portion of the bending induction portion toward an outside in the longitudinal, in which an amount of the resin material per length in the longitudinal direction is larger on the outside of the bending induction portion than on an inside of the bending induction portion.

The invention relates to an elongate profile extending in a longitudinal direction and having a first end and a second end, wherein between the first end and the second end the profile has at least one cutting line forming a cutting pattern for at least one profile section to be removed from the profile, wherein after removal of the at least one profile section from the profile the first end of the profile is bendable towards the second end of the profile and/or vice versa.

A structural member includes an inflatable bladder. The structural member may include a fabric shell disposed about an exterior surface of the bladder, or a spacer element attached to an interior surface of the bladder. The fabric shell or spacer element restrains the shape of the bladder to contour the bladder into a desired shape and increase the load carrying capacity of the bladder.
