The
structure modulus elasticity of foam cannot
be
determined as usual from the slope of the stress strain curve. This is due to plastic deformations in the early stress stages. Elastic vibration loading is therefore the more appropriate method.
Alulight® was tested as follows: The rod-shaped sample was vibrated longitudinally with an "impact-hammer".
Test sample: Alulight rod-shaped specimens (diameter of 17 mm, min. length of 300 mm) with varying densities and base alloy compositions were used for the
tests.
Summary of Results:
-
the
storage modulus of Alulight® does not depend on resonant
frequency - it can be considered as a static value of the
modulus
-
Alulight's® modulus of elasticity depends strongly on density. The dependence
obeys the power law function with an exponent of about 1.6
-
the base alloy composition has no significant influence on the modulus of
elasticity of Alulight®
(tests with densities
up to 1000
kg/m3).

Main Applications:
-
stiff structural components with minimized
masses
-
especially beam and membrane-like structures
-
as a filling material for hollow structures Alulight® helps to move resonant frequencies outside operating frequency range
-
heat resistant structures with high stiffness and low density made at reasonable
cost
-
isotropic properties, non-combustibility, form
stability and simple recycling make it an alternative to wood (Alulight® floats on water)
-
heat resistant, isotropic and stiff cores for sandwich structure
