This means that, for the thickness imposed by the metal spacers, the pressure was high enough to impregnate
the fibers but considering the higher resin viscosity and the imposed prepreg thickness of 0.6 mm, it did not allow the fibers
to disperse uniformly throughout the thickness of the cavity. This created a resin rich layer on one side of each prepreg, which remained in place during final molding of the seven layers plaque, even if the final molding cavity was 0.2 mm thinner than the uncompressed seven prepreg layers (4 mm versus 4.2 mm).
