Abstract
The disclosure relates to a resin flow enhancing member, including a cavity with a first opening and a second opening as well as an resin flow adjusting arrangement for changing a resin flow cross section in a resin flow direction from the first opening to the second opening in the resin flow enhancing member by applying vacuum to the second opening. The disclosure further relates to a fiber reinforced plastic laminate including a fiber stack and at least one resin flow enhancing member as well as to a fiber reinforced plastic composite material prepared by using a resin flow enhancing member. The disclosure further relates to a vacuum assisted resin transfer molding process for injecting resin from a resin flow enhancing member into a fiber stack.
Claims10
A resin flow enhancing member for the use in a vacuum assisted resin transfer moulding process, comprising:
- a cavity with a first opening connectable to a resin inlet of an VARTM apparatus and a second opening connectable to a vacuum pump of a VARTM apparatus, and a resin flow adjusting arrangement for changing a resin flow cross section in a resin flow direction from the first opening to the second opening in the cavity by applying vacuum to the second opening, wherein the resin flow adjusting arrangement comprises a plurality of vacuum expandable filler elements comprising gas-filled closed cell cavities and flexible walls.
