Aluminum Faced Foam Core Panels
图
The middle of the sandwich panel is a relatively thick and light carbon fiber honeycomb sandwich, which supports the upper and lower panels and bears the load and lateral shear force transmitted between the panels and the sandwich core;
The upper and lower surfaces of the sandwich panel are relatively thin and high-strength panels, whose main function is to bear in-plane loads, etc.
Adhesives, which bond the upper and lower panels and the honeycomb sandwich together, can transfer the shear force from the panels to the honeycomb sandwich and from the honeycomb sandwich to the panels.
Aluminum faced foam core panels can achieve a sufficiently thick sandwich panel with the minimum weight, but the weight of traditional panels without sandwich materials will be greatly increased under the same bending strength.
Carbon fiber foam sandwich panels, with a common thickness of 5.85mm, have a surface layer of 3K-2/2 twill carbon fiber cloth and a bottom layer of alkali-free glass fiber cloth, which are light in weight and high in rigidity. They are made by lamination and vacuum pressurization, with good bonding strength and low glue content. This can produce flat panels with smooth surfaces.

Polypropylene honeycomb VS aluminum honeycomb
Carbon fiber sandwich panels made of aluminum faced foam core panels and polypropylene honeycomb core are different. Different sandwich materials can have a better effect in different working environments.
| Features | PP honeycomb | Aluminum honeycomb |
| Weight | Lighter | Heavier |
| Strength and rigidity | Lower | Higher |
| Corrosion resistance | Excellent | Not corrosion resistant, requires surface treatment |
| Energy absorption effect | Excellent | Good |
| High and low temperature resistance | Poor | Excellent |
| Flame retardant | Flammable | Non-flammable |
| Cost | Lower | Higher |
| Manufacturing difficulty | Lower | Higher |
The resolution of the X-ray system using aluminum faced foam core panels is 4.01LP/mm, which meets the imaging resolution requirements of the medical equipment system for this panel. After filming, the film was inspected under a dedicated fluorescent lamp. There was no shadow visible to the naked eye, and no impurities with a diameter greater than 0.3mm were found after magnification, which fully met the relevant photographic index requirements.
