The disclosure relates to a fibre reinforced plastic composite material, including a vacuum assisted resin transfer moulded fibre reinforced plastic laminate prepared by use of 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 resin flow adjusting arrangement includes a plurality of vacuum expandable filler elements that includes gas-filled closed cell cavities and flexible walls. The disclosure further relates to a vacuum assisted resin transfer moulding process for injecting resin from a resin flow enhancing member into a fibre stack.
A fibre reinforced plastic composite material, comprising:
A vacuum assisted resin transfer moulding process for injecting resin from a resin flow enhancing member into a fibre stack, wherein the resin flow enhancing member comprises a cavity with a first opening connectable to a resin inlet of a VARTM apparatus and a second opening connectable to a vacuum pump of a VARTM apparatus, a resin penetrable wall or openings for penetration of resin into the fibre stack, and a resin flow adjusting arrangement, comprising changing a resin flow cross section of the cavity in a resin flow direction by applying vacuum at 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.
