Abstract:
A flexible pipe includes: an inner liner formed as a tube and having an outer surface and an inner surface defining an inner diameter; a reinforcement layer bonded to the inner liner and including at least a first ply of reinforcing tape helically wrapped in a first helical direction about the inner liner and a second ply of reinforcing tape helically wrapped about the first ply of reinforcing tape, the second ply of reinforcing tape helically wrapped in a second helical direction opposite to the first helical direction; and an outer jacket applied over and bonded to the reinforcement layer, the outer jacket including a thermoplastic. A reinforcing tape for use in the pipe or other applications includes: a plurality of reinforcing fibers and a matrix about the plurality of reinforcing fibers to hold the reinforcing fibers in the form of a tape, the matrix including thermoplastic and an additive to increase the impact resistance of the thermoplastic.
