Sound Proof A3003H18 Perforated Aluminum Honeycomb Core
General Instruction:
The A3003H18 aluminum honeycomb core is a porous discontinuous material, and the solid portion has a small cross-sectional area and a large surface area, so the density of the honeycomb core is very low. In fact, the honeycomb material itself does not have thermal insulation and sound insulation properties, but after being composed of the aluminum plate, the honeycomb core plate has good heat insulation and sound insulation properties. In the honeycomb aluminum plate, the volume of the solid portion is only 1% to 3%, and the remaining space is air in a sealed state, and the heat insulating and sound insulating properties of the air are superior to any solid material. In addition, it has a large specific surface area due to the special structure of the honeycomb structure. When the sound wave contacts the metal surface, it diffuses into the hole of the honeycomb metal, and the internal vibration of the metal converts the sound wave into heat energy, which also serves as a sound absorbing effect.

Applications:
Aluminum honeycomb cores are widely used, and honeycomb cores of different specifications may be used differently. For example, microporous honeycomb cores can be used as filter materials, and general-purpose honeycomb cores can be used as composite materials.
1. Commonly used honeycomb cores: honeycomb cores with common lengths ranging from 4mm to 6mm are generally used in composite panels as composite materials, the most common being aluminum honeycomb composites, aluminum ceiling composites and stone composite panels. Wait;
2. Use of microporous honeycomb core and small aperture honeycomb core: small aperture honeycomb cores with side lengths of 1.5mm to 3mm can generally be used as filter materials, lampshade materials (light filtering), paper honeycomb composite materials, etc.
