| Abstract: | The paper presents the most important mechanical properties determined in a simple tensile test on a 0.4 mm thickness 2/2 carbon twill weave fabric impregnated with epoxy resin, used as skins for an advanced ultralight sandwich composite structure with expanded polystyrene as core. The sandwich panel is subjected to flexural load-unload tests . This kind of fabric presents very good drapeability and is suitable to reinforce a quite large range of epoxy resins. The aim of using this fabric is to obtain thin structures with complex shapes and high stiffness for the automotive industry. A comparison with a sandwich structure with EWR-300 glass fabric/epoxy resin skins has been accomplished. Due to its high stiffness, the twill weave carbon fabric is used as skins in large sandwich structures even with low stiffness cores. The flexural load-unload tests show an outstanding stiffness of the whole sandwich panel. |
