- A design concept for composite wind tunnel compressor blades at NASA Ames Research Center was based on a sandwich construction composed of carbon fiber-reinforced polymer (CFRP) skins bonded to a syntactic foam core. The detailed design and analysis of this blade required the input of the elastic and strength properties of the sandwich constituents. Available standards that apply to regular foams and honeycomb cores were found to be partly inadequate for this purpose. An improved testing procedure and its analysis that provided the basic elastic and strength properties are reported in this paper. Tensile, compressive, and shear properties of the foam and skin are identified using beam deflection and failure mode analysis.
