Abstract
A multilayer structure suitable for the manufacture of vessels, in particular pressure vessels, for the storage and transportation of gasses. The vessel is particularly adapted for the storage and transportation of compressed gasses in vehicles.
Claims18
A multilayer structure comprising at least one barrier layer, and at least one composite layer, in contact with the at least one barrier layer wherein:
- Layer (BL) comprises a polyamide polymer PA1;
- and
- Layer (CL) comprises continuous reinforcing fibers and a polyamide polymer PA2,
- wherein:
- polyamide polymer PA1 is selected from the group consisting of the polyamides comprising recurring units deriving from the polycondensation of i) caprolactam;
- and/or ii) at least one diamine component having 4 to 8 carbon atoms and at least one dicarboxylic acid component having 8 carbon atoms or less;
- polyamide polymer PA2 is selected from the group consisting of the polyamides consisting of recurring units deriving from the polycondensation of at least one diamine component, said diamine component having at least 9 carbon atoms, at least one aromatic dicarboxylic acid component and optionally one or more components selected from the group consisting of lactams, aminoacids and aliphatic dicarboxylic acids.
