ABSTRACT:
The method includes the preparation of a preimpregnated product that undergoes a heat treatment between 70 and 1100 deg. C., is embedded with an inert substance that comprises a charge and a polymeric binder in a quantity greater than the volume of the voids of the single-layer yarn which is calculated by means of the formula [1], where mnis the mass of inert substance, dnis the density of the inert substance, a is the length of the preimpregnated product, b is the width of the preimpregnated product, h is the thickness of the preimpregnated product, mpris the mass of the preimpregnated product, and dfibis the density of the fiber, and is heated between 160 deg. C. and 200 deg. C., a pressure of between 1 and 5 MPa being applied simultaneously.mn=dn·(a·b·h-mprdfib).[1]
