Frequently Asked Questions
Q
What is the difference between Aluminum Core and Polypropylene Core panels?
Aluminum Core panels offer significantly higher flatwise tensile strength and climbing drum peel resistance compared to Polypropylene Core panels. The Aluminum Skin/Aluminum Core variant achieves up to 998 lb/in² tensile strength, making it ideal for structural and high-load applications. Polypropylene Core panels, on the other hand, are lighter and offer excellent compressive strength relative to their weight, suiting applications where weight savings are a priority.
Q
Which panel type provides the highest stabilized compressive strength?
The Fiberglass Skin/Polypropylene Core panel offers the highest stabilized compressive strength at 13,015 lb/in² (3.53 N/mm²), which is substantially higher than both the Aluminum Skin/Aluminum Core (749 lb/in²) and the Epoxy Fiberglass Skin/Aluminum Core (369 lb/in²) options.
Q
What thickness options are available for these composite panels?
All three panel types — Epoxy Fiberglass Skin/Aluminum Core, Aluminum Skin/Aluminum Core, and Fiberglass Skin/Polypropylene Core — are available in thicknesses ranging from 6 mm to 25 mm, providing flexibility for a wide range of structural and design applications.
Q
Which panel type is the lightest option available?
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 starting options. The Aluminum Skin/Aluminum Core panel is heavier, starting at 5.16 kg/m², due to the denser aluminum skin material.
Q
What does "Climbing Drum Peel Strength per unit width" indicate?
Climbing Drum Peel Strength measures the force required to separate the face skin from the core material of a sandwich panel. It is a key indicator of the bond quality between the skin and core. The Aluminum Skin/Aluminum Core panel has the highest value at 92 lbf (407 N), indicating the strongest skin-to-core adhesion among the three panel types listed.
Q
Which panel is best suited for aerospace or high-performance structural applications?
The Aluminum Skin/Aluminum Core panel is generally the preferred choice for aerospace or high-performance structural applications due to its superior flatwise tensile strength (998 lb/in²), highest climbing drum peel resistance (92 lbf), and strong compressive strength (749 lb/in²). Its all-aluminum construction also provides excellent durability and resistance to environmental stresses.
