During vacuum infusion process (referred to as VIP), reinforced materials (such as fiberglass, carbon fiber and sandwich materials, different from vacuum bag process) shall be applied on moulds and vacuum bag shall be applied and vacuum shall be pumped to form negative pressure within the mould cavity. Pressure generated from vacuum shall be employed to compress the unsaturated resin into the fiber layer via the pre-applied pipe and resin impregnated reinforced materials shall fill the whole mould. After the product is cured, vacuum bag materials shall be ripped off and required product can be obtained from the mould. vacuum infusion process became known to the world long time ago. Since it is introduced from abroad, it has many other names such as vacuum infusion, vacuum irrigation and vacuum injection.
