Abstract:
A spoolable composite tube extending along a longitudinal axis, the composite tube comprising:a substantially fluid impervious pressure barrier layer, a composite layer formed of a first set of fibers embedded in a matrix, the composite layer and the pressure barrier layer together comprising at least a portion of a wall of the tubular member, at least 80%, by fiber volume, of the fibers of the first set of fibers being helically oriented relative to the longitudinal axis at an angle of between 30Â° and 70Â°, the matrix having a tensile modulus of elasticity of at least 100,000 psi to contribute to the ability of the tube to withstand tensile strains imposed on the tube when the tube is spooled on a reel, an energy conductor extending lengthwise along the tubular member and embedded in the wall of the tubular member, and a sensor mounted with the wall of the tubular member and connected for signal communication by way of the energy conductor, the sensor being capable of responding to an ambient condition of the tubular member.
