Improved Manufacturing Technologies for Aircraft Engines

The overall objective of this SBIR Phase I program is to develop a cost-effective method for manufacturing resin transfer molding (RTM) polyimide resins on a continuous basis. Specialized compounding equipment will be utilized to convert a "dry blend" of monomers into Maverick's high-temperature MM-10.8 resin system. This technology will not require the use of a solvent, and thus is considered to be an environmentally friendly process. The cost savings associated with removing the polyimide reactor and subsequent oven unit operation will be extremely significant. Experimental compounding trials will be conducted in order to determine temperature profiles and overall process parameters. Molecular weight distribution, monomer to polyimide conversion, and minimum melt viscosity will be determined on all prospective samples. Maverick plans to team with Berstorff to design the extrusion experiments, and to work with Fiber Innovations, Inc. to RTM composite panels for physical and mechanical testing. This unique collaboration will be key towards the successful development of a low-cost, high-temperature RTM system.
