❓ Frequently Asked Questions
Q
What is the difference between Aluminum Skin/Aluminum Core and Epoxy Fiberglass Skin/Aluminum Core panels?
The Aluminum Skin/Aluminum Core panel offers significantly higher mechanical performance, with a flatwise tensile strength of 998 lb/in² compared to 644 lb/in² for the Epoxy Fiberglass Skin/Aluminum Core. It also provides greater climbing drum resistance (92 lbf vs. 52 lbf) and higher stabilized compressive strength, making it better suited for structurally demanding applications.
Q
Which panel type has the highest stabilized compressive strength?
The Fiberglass Skin/Polypropylene Core panel has the highest listed stabilized compressive strength at 13,015 lb/in² (3.53 N/mm²), which is considerably higher than both the Aluminum and Epoxy Fiberglass skin panels. This makes it particularly advantageous in applications where compressive load resistance is a priority.
Q
Are all three panel types available in the same thickness range?
Yes, all three panel types — Epoxy Fiberglass Skin/Aluminum Core, Aluminum Skin/Aluminum Core, and Fiberglass Skin/Polypropylene Core — are available in the same thickness range of 6 mm to 25 mm, offering flexibility for various design and engineering requirements.
Q
Which panel type is the lightest in terms of weight?
Both the Epoxy Fiberglass Skin/Aluminum Core and the Fiberglass Skin/Polypropylene Core panels share the lowest minimum weight at 3.9 kg/m². The Aluminum Skin/Aluminum Core panel is the heaviest, ranging from 5.16 kg/m² to 8.21 kg/m², which should be considered in weight-sensitive applications.
Q
What does "Climbing Drum (Per Unit Width)" measure in these panels?
The Climbing Drum value measures the peel strength of the bond between the skin and the core of a sandwich panel, tested per unit width. A higher value indicates a stronger skin-to-core adhesion. 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
How do I choose the right panel type for my application?
Choosing the right panel depends on your specific application requirements. If you need maximum tensile and peel strength, the Aluminum Skin/Aluminum Core is the top performer. For a balance of light weight and moderate strength, the Epoxy Fiberglass Skin/Aluminum Core is a strong choice. If compressive strength and lower cost are priorities, the Fiberglass Skin/Polypropylene Core may be the best fit. Consulting with a structural engineer is recommended for critical applications.
