Abstract
A composite tube structure is disclosed in which the end of the composite tube is either flared out at the end or is tapered in at the end and the flared or tapered portion is accurately formed to its final dimension so as to require no machining to size. An end assembly is applied to the end of the tube which has inner and outer portions fitting precisely into the inner and outer surfaces of the end of the tube. The inner and outer end pieces are drawn axially together to secure the tube in the end assembly between the inner and outer portions under a predetermined radial stress. The tube is secured to the end assembly without the use of pins or other fasteners which require severing the fiber strands of the tube.
