Frequently Asked Questions
Q
What is the difference between Aluminum Skin/Aluminum Core and Epoxy Fiberglass Skin/Aluminum Core panels?
A
Aluminum Skin/Aluminum Core panels offer significantly higher mechanical performance, with a flatwise tensile strength of 998 lb/in² compared to 644 lb/in² for Epoxy Fiberglass Skin/Aluminum Core panels. They also provide a higher climbing drum value (92 lbf vs. 52 lbf) and greater stabilized compressive strength, making them better suited for structurally demanding applications.
Q
Which panel type has the highest stabilized compressive strength?
A
The Fiberglass Skin/Polypropylene Core panel has the highest stabilized compressive strength at 13,015 lb/in² (3.53 N/mm²), making it an excellent choice for applications where compressive load resistance is the primary concern.
Q
Are all three panel types available in the same thickness range?
A
Yes, all three panel types — Epoxy Fiberglass Skin/Aluminum Core, Aluminum Skin/Aluminum Core, and Fiberglass Skin/Polypropylene Core — are available in a consistent thickness range of 6 mm to 25 mm, allowing for flexible design and application choices.
Q
Which panel type is the lightest option available?
A
Both the Epoxy Fiberglass Skin/Aluminum Core and the Fiberglass Skin/Polypropylene Core panels share the same minimum weight of 3.9 kg/m², making them the lightest options at the lower end of their weight range. This makes them ideal for weight-sensitive applications.
Q
What does the Climbing Drum value indicate in panel performance?
A
The Climbing Drum value (measured per unit width) represents the peel strength of the panel — specifically the force required to separate the skin from the core. A higher value indicates stronger skin-to-core bonding. The Aluminum Skin/Aluminum Core panel leads with 92 lbf (407 N), followed by Epoxy Fiberglass at 52 lbf (231 N), and Fiberglass/Polypropylene at 22 lbf (98 N).
Q
Which panel is most suitable for applications requiring a balance of light weight and structural strength?
A
The Epoxy Fiberglass Skin/Aluminum Core panel offers a strong balance between low weight (starting at 3.9 kg/m²) and solid structural performance, including a flatwise tensile strength of 644 lb/in² and a stabilized compressive strength of 369 lb/in². It is well-suited for aerospace, marine, and transportation applications where both properties are critical.
