Abstract
A method of infusing liquid resin into a sheet of fibrous material comprises evacuating gaseous contaminants from the sheet of fibrous material through a permeable media layer to an outlet and comprises flowing liquid resin from an inlet through the permeable media layer. The method further comprises infusing the liquid resin into the sheet of fibrous material and selectively adjusting a distance between the non-permeable bladder and the fibrous material at a gap, formed in the permeable media layer, such that a first resistance to fluid flow through the permeable media layer is reduced.
