Another type of structural sandwich construction
consists of a low-density balsa wood core combined
with high-strength aluminum alloy facings bonded to
each side of the core. The grain in the balsa core runs
perpendicular to the aluminum alloy facings, and the
core and aluminum facings are firmly bonded together
under controlled temperatures and pressures.
The facings in this type of construction carry the
major bending loads, and the cores serve to support the
facings and carry the shear loads. The outstanding
characteristics of sandwich construction are strength,
rigidity, lightness, and surface smoothness.
