1. A manufacturing method for manufacturing a part made of composite material with a continuous fiber reinforcement, the method comprising the steps:
a) providing a body with tubular cavities and having at least one first portion made from a first polymer material and at least one second portion made from a second polymer material, wherein the body comprises at least 60%, by weight, of the second polymer material, and wherein the second portion forms at least a portion of walls of the tubular cavities;
b) introducing resin and continuous fibers into the tubular cavities; and
c) at least partially removing the second polymer material;
wherein step a) comprises:
a1) selecting the second polymer material from materials that are soluble in a solvent and the first polymer material from polymer materials that are non-soluble in the solvent; and
wherein step c) comprises:
c1) dissolving the second polymer material in the solvent.
