The strength characteristics of aluminum honeycomb sandwich panels
TL;DR: In this paper, a series of strength tests are carried out on aluminum honeycomb-cored sandwich panel specimen in three point bending, axial compression and lateral crushing loads and simplified theories are applied to analyze bending deformation, buckling/ultimate strength and crushing strength of honeycomb sandwich panels subject to the corresponding load component.

Thermoplastic impact property improvement in hybrid natural fibre epoxy composite bumper beam
TL;DR: In this paper, thermoplastic toughening has been used to improve impact properties in hybrid natural fiber epoxy composite for automotive bumper beam and has achieved reasonable impact improvements, which form single phase or two-phase morphology to make modifier as epoxy or from separate phase to keep the thermo-mechanical properties.
