As the size of composite parts exceed that of even the largest autoclaves, new out-of-autoclave processes and materials are necessary to achieve the same level of performance as autoclave cured composites. As an alternative to OOA prepreg systems, infusion of dry fiber preforms made by automated dry fiber placement (ADFP) can mitigate out-time issues and shelf-life problems combined with lower cost manufacturing. Although improvements in ADFP products have continued, use and application of these ADFP products have been limited due to the necessary balance of processing and performance of the infusion resin. This is a result of not only the low permeability of the ADFP product preforms but also the inadequate damage tolerance and micro-crack sensitivity of the developed composites. Accordingly, Applied Poleramic, Inc. proposes to develop a novel low viscosity, long pot-life infusion resin for use with ADFP product preforms that results in cured performance similar to that of unidirectional Hexcel 8552 prepreg parts. Specifically, the infusion resin will be capable of significantly lower infusion temperature (less than 150 ⁰F) as compared to current commercial infusion resins along with improved fracture toughness. This innovative epoxy infusion resin will enable large complex composite structures to be developed using ADFP product preforms with lower manufacturing risk, reduced production time, higher part quality, and a new level of performance not attainable with current commercial infusion resins. Ultimately, the technology will lead to a new generation of low cost composite materials, critical to future NASA space programs and missions.
