Abstract
A columnar structure comprises a generally hollow laminate core, an outer composite skin, and a sleeve-like reinforcement. The sleeve-like reinforcement surrounds the laminate core and is sandwiched between the laminate core and the outer composite skin for reacting compressive loads imposed on the columnar structure.
Claims24
A columnar structure, comprising:
- a generally hollow composite laminate core;
- an outer composite skin;
- and
- a reinforcement surrounding the composite laminate core and sandwiched between the composite laminate core and the outer composite skin for reacting at least compressive loads imposed on the columnar structure.

A strut, comprising:
- a generally tubular, fiber reinforced resin core;
- and
- a sleeve-like reinforcement around the fiber reinforced resin core having a compressive strength greater than the compressive strength of the fiber reinforced resin core.
A method of making a strut, comprising:
- fabricating a composite laminate core;
- fabricating a sleeve-like reinforcement;
- assembling the sleeve-like reinforcement over the composite laminate core;
- and
- fabricating an outer skin over the sleeve-like reinforcement.
