Lightweight Flame Retardant Aramid Honeycomb Core For Aerospace Interior Panel
Lightweight Flame Retardant Aramid Honeycomb Core For Aerospace Interior Panel
This product is a sandwich panel designed for aerospace interior applications, constructed with a lightweight aramid honeycomb core bonded between reinforced skins. It delivers an exceptional strength-to-weight ratio while meeting the stringent flammability requirements of FAR 25.853 for aircraft cabin interiors.
Key Features
· Ultra-Lightweight Construction: Aramid fiber honeycomb core significantly reduces panel weight without compromising structural integrity
· Excellent Flame Retardant Performance: Self-extinguishing properties with low heat release and minimal smoke emission
· High Strength-to-Weight Ratio: Superior mechanical properties per unit weight compared to conventional core materials
· Corrosion Resistance: Inherent resistance to moisture, chemicals, and fungal growth
· Excellent Thermal Stability: Service temperature up to 180°F (82°C)
Applications
· Overhead stowage bins
· Ceiling panels
· Cabin sidewalls
· Partitions and bulkheads
· Galleys and lavatory structures
