| Résumé : |
Permeability is one of a reinforcement's intrinsic properties that must be controlled during the manufacture of a part made of a composite material. This property can be illustrated as the average cross section of the microchannels where the resin flows during reinforcement impregnation in liquid composite moulding [LCM) technologies such as RTM. |
