Experimental and numerical assessment of sustainable bamboo core sandwich panels under low-velocity impact

This work describes the experimental and numerical behaviour of sandwich panels made of aluminium skins and bamboo core under low-velocity impact test. A statistical design is carried out to evaluate the effect of the bamboo diameter (Ø20 and Ø30 mm) and the adhesive type (epoxy and biopolymer) on the maximum load, energy to maximum load, total deflection and total energy of the panels, which are assessed through graphical and failure analysis....
