| Summary: | Aluminum foam sandwich (AFS) panels are one of
an advanced material that has various advantages such as
lightweight, excellent stiffness to weight ratio and high-energy
absorption. Due to their advantages, many researchers’ shows an
interest in aluminum foam material for expanding the use of
foam structure. However, there is still a gap need to be filling in
order to develop reliable data on mechanical behavior of AFS
with different parameters and analysis method approach. There
are two types of aluminum foam that is open-cell and closed-cell
foam. Few researchers were focusing on open-cell aluminum
foam. Moreover, open-cell metal foam had some advantages
compared to closed-cell due to the cost and weight matters. Thus,
this research is focusing on aluminum foam sandwich using
open-cell aluminum foam core with grade 6101 attached to
aluminum sheets skin tested under three point bending. The
effect Skin to core ratio investigated on AFS specimens analyzed
by constructing load-displacement curves and observing the
failure modes of AFS. Design of experiment of three levels skin
sheet thickness (0.2mm, 0.4mm, and 0.6mm) and two levels core
thickness (3.2mm and 6.35mm). a full factorial of six runs were
performed with three time repetition. The results show that when
skin to core ratio increase, force that AFS panels can withstand
also increase with increasing core thickness. |
