1. Flatwise Compressive Strength
The average compressive strength of the aluminum honeycomb panel reaches 1.39 MPa, with data ranging from 1.35 MPa to 1.42 MPa. Stable data fluctuation proves uniform core bonding and consistent cell structure.
2. Flatwise Compressive Modulus
Average compression modulus is 77.38 MPa, indicating outstanding stiffness under vertical load, excellent resistance to deformation under static compression.
3. Load-Displacement Curve Feature
All three curves show consistent linear elastic stage before peak load, no sudden collapse in advance. After reaching maximum bearing force, the panel slowly deforms without instant breakage, showing good energy absorption performance.
This aluminum honeycomb panel features lightweight, high flatwise compression resistance, stable mechanical performance. It is widely applicable for buil6ding decoration, transportation vehicle interior, equipment partition and industrial equipment housing.
