First Claim
1. A co-cured vacuum-assisted resin transfer molding manufacturing method comprising:
- providing a tool base;
disposing a prepreg skin panel outwardly from the tool base;
disposing one or more tooling details outwardly from the prepreg skin panel;
disposing one or more preforms proximate the one or more tooling details, the one or more preforms being either dry or binderized;
disposing a film adhesive between the prepreg skin panel and the one or more preforms;
disposing a high permeability medium between the one or more tooling details and the one or more preforms;
enclosing the prepreg skin panel, the one or more tooling details, the one or more preforms, and the high permeability medium with at least one vacuum bag;
pulling a vacuum on the vacuum bag;
infusing the one or more preforms with a resin; and
curing the one or more preforms and the prepreg skin panel.

Abstract
According to one embodiment of the invention, a co-cured vacuum-assisted resin transfer molding manufacturing method includes providing a tool base, disposing a prepreg skin panel outwardly from the tool base, disposing one or more tooling details outwardly from the prepreg skin panel, and disposing one or more preforms proximate the one or more tooling details. The one or more preforms are either dry or binderized. The method further includes disposing a high permeability medium between the one or more tooling details and the one or more preforms, enclosing the prepreg skin panel, the one or more tooling details, the one or more preforms, and the high permeability medium with at least one vacuum bag, pulling a vacuum on the vacuum bag, infusing the one or more preforms with a resin, and curing the one or more preforms and the prepreg skin panel.
