Development of Air Bonded FOD Resistant Metal Matrix Fan Blades

Abstract

Advanced Composite aluminum matrix fan blades offer significant payoff to Air Force systems in terms of both cost saving and performance improvements. However, there are currently problems which must be overcome prior to the introduction of such blades to service. Two problem areas have been identified for solution before aluminum matrix composites can be applied to Air Force weapon systems - high cost and inadequate FOD resistance. Low cost bonding fabrication techniques have been identified, and feasibility demonstrated. Improved FOD resistance of boron aluminum composites has been explored on laboratory specimens and full size blades. This program will combine the previously identified solutions to FOD resistance with low cost bonding fabrication to provide a basis for validation of these technologies for future blade hardware. The fabrication approach will be air and 'quick vac' bonding.
