The composite material is rigid, resistant to blows, breakage and pressure
and has high bending, buckling and breaking strengths.
The strength is determined by the 0.5mm thick aluminium cover sheets in
Peraluman-100, EN AW-5005 (AlMg1), acc to EN 485-2.
|
Mechanical properties of the cover sheets:
| Tensile Strength: |
Rm130N/mm2 |
| 0.2% proof stress |
Rp0.2 90N/mm2 |
| Elongation: |
A5.0 5% |
| Modules of elasticity: |
E = 70000N/mm2 |
Since the cover sheets determine the bending strength, the core material can
be disregarded when calculating the bending tension.
Features
The composite structure of ALUCOBOND® - two aluminium cover sheets and
a plastic or mineral filled core - results in an impressive strength-to-weight
ratio, even when comparing large panel sizes. Despite its low weight, which
makes ALUCOBOND® easy to transport and handle in the factory and on site,
its rigidity and high strength make it the most suitable material for exterior
wall cladding. When properly designed and installed, ALUCOBOND® panels will
keep their shape and remain flat for life, even when exposed to extreme temperatures.
