The design and development of a composite material front housing for the reduction gear of the T56 engine are discussed. The program was undertaken to advance the state-of-the-art in engine structures by making a material available that is capable of replacing aluminum and magnesium. The selected boron-glass-epoxy material exhibits high strength and specific stiffness, light weight, good corrosion resistance, and suitability for molding. The design, molding, machining, and testing phases of the programs are described.
