    Porosity is highly dependent upon the arrangement the shape and the size of the material. However the diameter of the grain size does not affect porosity since it is the ratio of open space volume to total volume. For example a box full of soccer balls and a box full of tennis balls will have the same porosity given they are packed the same way.

    Preform porosity. Porosity represents the packing density of the preform in the cavity. Porosity is defined as the ratio of the void volume to the cavity volume before the cavity is filled with resin. The void volume is equal to the cavity volume minus the volume occupied by the fiber reinforcement.
