N2 - The vacuum infusion process is a Liquid Composite Manufacturing (LCM) process in which the preformed reinforcing fibres are impregnated with the fluid matrix using the pressure difference produced by the evacuation of the mould cavity. In order to speed up the infiltration process, it is common to use a highly permeable flow distribution medium on top of the preform.
