The Effects of Various Adhesives on Multiple Types of Quasi‐Static Mechanical Properties
of Rectangular and Square Aluminum Hollow Sections Filled with Composite Metal Foam
Cores
For composite metal foam structures to be used as load‐bearing and energy‐absorbing
elements, comprehensive testing should be done. Therefore, an extensive characterization
of foam‐filled structures by various load types, such as axial and lateral compression,
as well as three‐point bending, is carried out, aiming to differentiate the behavior
of various cross‐sectional geometry foam‐filled hollow sections and the application
of a tough epoxy adhesive and a ductile polysiloxane adhesive. Applying the epoxy
adhesive improves the overall energy absorption by 10 % during axial compression compared
to the sum of the foam and empty hollow section. The application of the polysiloxane
adhesive over the epoxy one increases the deflection at failure during three‐point
bending by an average of 58 %. The deformation and strength during axial compression
and three‐point bending are hollow section dominated, while the foam core dominates
the deformation and the strength during lateral compression for both produced composite
foam‐filled hollow sections with epoxy and polysiloxane adhesive bonding.
