Thermoplastic composite hose for transporting fluid and flexible pipe comprising same

A thermoplastic composite pipe intended for transporting fluids, comprising from the inside toward the outside:

• a tubular internal sheath of axis (A-A′) defining an inner passageway for the circulation of fluids;
• and
• a reinforcing composite structure around the tubular sheath and which is bonded to the tubular sheath, the reinforcing composite structure comprising a winding of at least two laminated reinforcing layers, each reinforcing layer being made from a thermoplastic matrix comprising a polyether ether ketone reinforced with carbon fibres, said polyether ether ketone having:
• a molecular weight distribution by gel permeation chromatography (GPC) such that:
• the number average molecular weight (Mn) is higher than 38,000 g/mol,
• the peak molecular weight (Mp) is higher than 70,000 g/mol, and
• the polydispersity index (PI) is lower than 2.3, and
• a Charpy Impact strength measured at 23° C. according to standard ISO 179/1eA of 2010 greater than or equal to 5.5 kJ/m2.
