Dynamic Compressive Response of Carbon Fibre Laminar Composite and Carbon Fibre Corrugated Sandwich Panel

摘要

Carbon fiber composite is widely used in aero industries and on automobile body panel due to its high strength and light weight. In order to achieve even better fuel economy, various sandwich panels with different core structures are being studied. In this study, Split Hopkinson Pressure Bar (SHPB) is utilized to conduct high strain rate compression tests on carbon fiber panel and carbon fiber sandwich panel. The fused deposition modeling method is utilized to manufacture corrugated cores which are glued onto carbon fiber face panels with epoxy resin. The main goal of the experiment is to discuss the specific strength and energy absorption differences of monolithic material and corrugated sandwich with same thickness.
