Abstract: A chemical vapor infiltration and deposition (CVI/CVD) reactor assembly includes a CVI/CVD reactor and a reactant gas feed source. The CVI/CVD reactor includes a first inlet at a first end of the CVI/CVD reactor, a second inlet at a second end of the CVI/CVD reactor opposite the first end, a first outlet at the second end, a second outlet at the first end, and a chamber in fluid communication with the first and second inlets and first and second outlets and configured to hold a substrate. The reactant gas feed source is interchangeably and fluidly connected to the first and second inlets by first and second valved gas lines, respectively.

Abstract: A method for making a composite article comprises securing a layup over a form. The layup including a plurality of dry intermediate reinforcement plies wrapped around an inner reinforcement ply. Resin is infused into the layup under vacuum. The resin-infused layup is consolidated under pressure and cured.

Abstract: A process for forming a composite structure includes the steps of: providing a preform having a plurality of layers; applying a tackifier to each of the layers of the preform; and infusing the preform with a resin. The tackifier may be catalyzed or uncatalyzed, thermoset or thermoplastic resin. The tackifier has a strain capability greater than the strain of the resin which infuses the preform.
