Abstract
Methods and manufactures disclosed herein generally relate to a tubular composite (TCS) structure composed of multiple layers of sealing, reinforcement, sensing, protection and interspatial injected materials.
Claims35
A tubular composite structure comprising a plurality of tubular assemblies, wherein each of the tubular assemblies comprises, from innermost surface to outermost surface:
- a sealing layer having a longitudinal axis defining an axial direction;
- one or more axial reinforcement layers each having a plurality of longitudinally extending filaments, wherein the one or more axial reinforcement layers are disposed around the sealing layer in a manner wherein the longitudinally extending filaments are oriented in and extend longitudinally along the axial direction for imparting axial reinforcement to the tubular assembly;
- a hoop reinforcement layer disposed around the one or more axial reinforcement layers to provide resistance to hoop stresses in the tubular assembly;
- and
- a protective layer,
- wherein each of the tubular assemblies further comprises a protective coating on at least one of the innermost surface of an innermost tubular assembly of the plurality of tubular assemblies or on the outermost surface of an outermost tubular assembly of the plurality of tubular assemblies.
