METHOD FOR PRODUCING A BLADDER FOR SEALING A TYPE IV RESERVOIR, AND CORRESPONDING TYPE IV RESERVOIR

摘要

The invention relates to a method for producing a thermoplastic polymer bladder (2) for sealing the gases in a type IV composite reservoir (1), and to a type IV reservoir that can be obtained by said method. The inventive method consists of a step for polymerising a precursor monomer of said thermoplastic polymer into said thermoplastic polymer in a rotating mould which is heated to a working temperature higher than or equal to the melting temperature of the monomer and lower than the melting temperature of the polymer, in such a way as to form the inventive bladder (2) by polymerisation of the monomer, coupled to a rotational moulding, and without the obtained thermoplastic polymer melting.
