The Sabre's airframe is constructed from a basis of superplastic-shaped diffusion-adhered metal matrix composites. These light, oxidation resistant light-matrix composites are formed from titanium/aluminum laminate matrix, formed by heat bonding layers of titanium, aluminum and titanium aluminide, forming high strength crystal matrices, the results forming a high strength, yet flexible and light airframe. The skin is formed from four layered plates attached to the frame.
