Resin infusion apparatus and system, layup system, and methods of using these

摘要

A resin infusion apparatus and system, layup system comprising the same, and methods of using these are provided. The resin infusion apparatus comprises a hollow cylinder having a plurality of pores perforating an arcuate surface thereof. The interior of the cylinder is provided with one or more flow restrictors that assist in controlling the flow out of the pores of the cylinder. Laminates made of prepregs prepared using the apparatus and/or system may thus be essentially free of voids.
