Multilayer structure comprising continuous fibers for transporting heat transfer fluid

Abstract

A tubular structure for transporting heat transfer fluid including at least: i) a layer (1) in contact with the fluid including at least one thermoplastic polymer P1 that is semicrystalline with Tm1 greater than or equal to 160° C., as determined according to the standard 1 1357-3 (2013) or amorphous with Tg1 greater than or equal to 100° C., as determined according to the standard 1 1357-2 (2013), said layer (1) containing no fibers, ii) a layer (2) including at least: (a) a thermoplastic polymer P2 that is semicrystalline, in particular a polyamide with Tm2 greater than or equal to 170° C. or amorphous with Tg2 greater than or equal to 100° C., or a polyolefin with Tm greater than 100° C.; (b) continuous fibers, the polymer P2 being identical to P1 or different from P1 in which case the polymers P1 and P2 adhere at least partially to one another.
