Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin infusion apparatus for forming a prepreg from a resin and a reinforcing material comprising: at least one hollow cylinder having a plurality of pores perforating an exterior surface of the hollow cylinder; and one or more hollow porous flow restrictors surrounding an orifice, wherein the one or more flow restrictors comprise metal foam discs having an outer diameter substantially equivalent to an inner diameter of the hollow cylinder and an inne…
