Mechanical Response of Composite Sandwich Panels: Deformation and Energy Absorption

Article Preview

Abstract:

The collapse modes and energy absorption in three-point bending of composite sandwich beams were explored experimentally. Sandwich beams manufactured from woven carbon fibre face sheets encapsulating aluminium foam cores were investigated at 0.001 s-1 and 100 s-1 strain rates. Three modes of failure were observed during deformation: Modes H1, H2 and H3. The direction of core shear played an important role in the energy absorption of the structure. Mode H2 gave rise to the highest specific energy absorption of the composite sandwich beams studied.
