Selection Guide for Aerospace Honeycomb Panels
-
Aluminum vs Aramid Honeycomb Core
Aluminum honeycomb cores are suitable for load-bearing and structural applications, while aramid honeycomb cores are preferred for lightweight interior panels and FST-compliant environments.
-
Density and Thickness Selection
Higher density cores provide greater strength and stiffness, while lower density cores reduce weight. Panel thickness should be selected based on load conditions and structural requirements.
-
Application-Based Recommendation
Interior panels typically use aramid cores, floor systems use aluminum honeycomb, and high-temperature components require stainless steel or titanium honeycomb structures.
