Professional Testing Lab for Aluminum Honeycomb Products

Our factory is equipped with a full professional test laboratory to verify the mechanical performance and anti-corrosion durability of all aluminum honeycomb cores and finished honeycomb panels, supporting four core standardized testing items: Flatwise Compression Test, Flexural Performance Test, Shear Strength Test and Salt Spray Corrosion Test. 

1. Flatwise Compression Test 

Test specimens are fixed on a universal testing machine for vertical compression. We record the maximum bearing force and compression deformation data to evaluate the flatwise compressive strength and load-bearing stability of honeycomb core, which is critical for energy absorption and load-bearing structural panels.

2. Flexural Performance Test

Three-point bending testing is adopted to detect the bending rigidity, deflection and breaking load of honeycomb sandwich panels. This test confirms the anti-deformation capacity when panels bear lateral bending force, guiding material matching for wall cladding, equipment housing and lighting brackets.

3. Shear Strength Test

Conducted in accordance with ASTM D1002 standard, the lap shear test pulls bonded layers along the bonding plane. It inspects the adhesive bonding tightness between aluminum foil honeycomb core and surface skins, ensuring no delamination under lateral shear force.

4. Neutral Salt Spray Test

Long-term salt spray aging test simulates coastal, humid and industrial corrosive environments. We monitor surface oxidation, black anodized coating peeling and aluminum substrate corrosion status, verifying the anti-rust and anti-fading performance of our lighting-grade black honeycomb cores for long-term outdoor and optical equipment use.

All test reports can be provided to clients upon request to prove stable product quality for lighting, new energy, transportation and construction industries. Contact us for customized testing solutions for your honeycomb products.
