How does a high-frequency vibration environment (e.g., near an engine) damage PU sandwich panels?
PU foam, being thermoset, has no distinct fatigue limit.[…]
For marine floating structures (e.g., floating bridges), why is closed-cell ratio more important than compressive strength when selecting a sandwich panel core?
During long-term immersion, core water absorption increases weight, reduces[…]
As a refrigerated truck floor, why are XPS sandwich panels prone to cracking at the wheel path during forklift turns?
The root cause is the low shear fatigue strength[…]
What is the shear buckling failure mode of sandwich panels? How to increase the critical shear stress?
When the core shear modulus is low, the facings[…]
How do differences in screw holding capacity among different foam cores affect curtain wall installation?
Curtain walls are attached to framing with screws, so[…]
Why do some XPS sandwich panels fail to fully recover their thickness after prolonged loading and unloading?
This is attributed to the elastic-plastic behavior of XPS[…]
In sports flooring systems, why does PET sandwich panel have poorer ball rebound performance compared to PVC?
Ball rebound height depends on the coefficient of restitution[…]
For fire protection design of building exterior wall sandwich panels, why is it insufficient to rely solely on the core’s flame retardancy rating?
In an actual fire, flames can enter the core[…]
Under high humidity conditions, which foam core maintains the highest long-term mechanical property retention? Provide test data comparison.
Long-term hygrothermal aging test results (70°C/95%RH, 1000 hours): Therefore,[…]
