FRP composite coil core tube

The FRP composite material core tube (shaft) used for optical thin film, copper foil, and aluminum foil winding is made by impregnating high-strength wear-resistant glass fiber with epoxy resin matrix on a four-dimensional CNC winding machine. According to the specifications, models, and dimensions required by the user, the glass fiber filament is wound at a certain angle on the steel winding core mold (calculated and designed according to the laying theory) to achieve better mechanical performance requirements. It is heated and rotated to wind to the set thickness, After secondary heating and solidification, it is then turned to the core tube (shaft) required by the customer's drawings. Used for rolling various optical films, copper foils, and aluminum foils, it is the preferred new material for optical film manufacturing, copper foil manufacturing, and aluminum foil manufacturing enterprises.

1 inch, 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, etc. Other specifications can also be produced and processed according to customer needs.

Advantages of FRP composite roll core tubes (shafts) for optical thin films, copper foils, and aluminum foils

1. Reducing losses, FRP composite core tubes have high strength, are not easily deformed, and have stable physical properties, which can prevent damage to the wrapped film caused by deformation of the core tubes.

2. The FRP composite material core tube has high processing accuracy and good surface smoothness, which can increase the utilization rate of the film.

3. The FRP composite core tube has a large load-bearing capacity, and its glass fiber fibers are cross wound at large and small angles, which gives the core tube axial and circumferential strength and high load-bearing characteristics.

4. The outer diameter surface of FRP composite core tube (shaft) can be repaired for secondary use and recycled.

5. Lightweight, compared to similar metal tubes (shafts), it weighs 1/4 of the weight and can be designed to save electricity and costs through lightweight design.

6. Widely used, it can be used for lithium battery separator copper foil winding core (shaft), PET copper foil winding core (shaft), etc.

7. Long lifespan, resistant to acid and alkali corrosion, never rusting, and free from maintenance.
