The Effect of Superficial Damage on the Mechanical Properties of Flexible Composite Pipe for Transporting Hydrocarbons. rev.ing. [online]. 2015, n.42, pp.39-48.

This research examines the influence of outer sheath scratching on the mechanical properties of two systems of flexible composite pipe with nonmetal-reinforcement for transporting hydrocarbons. Tensile testing was carried out on notched rings, using Shore D hardness testing, and by physical characterization using cofocal microscopy on specimens with and without superficial damage. The tests were conducted following international technical standards and specifications. The results showed that variation in the depth and spacing of scratches affect the mechanical properties of the pipe, reducing ultimate tensile strength and leading to unit deformation. The effects are greater the deeper the scratche
