    Abstract

    National Aeronautical Laboratory, Bangalore is involved in a collaborative program in the field of composite structures with DFVLR, West Germany. This is a technology demonstration program where the example chosen is rudder of DO 228 aircraft (a civilian aircraft which is of interest to India and West Germany). Preliminary design studies of composite rudder indicates that carbon fibre in the fabric form will be used as reinforcement in fabrication of spar, ribs and skins. Hence, mechanical properties of carbon-epoxy composites are required for design. Various carbon fibre manufacturers give these values in their catalogues but these values correspond to prepreg systems for specific resins. As we have decided to use indigenous resin (LY 556 with various hardeners) systems for the present activity, a need to determine the basic mechanical properties was realised. This investigation is aimed to generate seven mechanical properties (four stiffnesses and three strengths) of carbon-epoxy composite with carbon-fabric as reinforcement and LY 556 + HT 972 as matrix. This work is carried out at NAL and DFVLR and the results are compared with each other. The comparison is found to be within experimental error.
