Why measure permeability?



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.
