FRP composite winding core shaft

The FRP composite material winding core tube (shaft) for optical film, copper foil, and aluminum foil winding is made of high-strength and wear-resistant glass fiber impregnated with epoxy resin on a four-dimensional CNC winding machine, According to the specifications and sizes required by the user, it is made on the steel winding core mold, the glass fiber filaments pass through a certain winding angle (theoretical calculation design of the lamination) to achieve better mechanical performance requirements. They are heated, rotated and wound to the set thickness. After secondary heating and solidification, they are then turned to core tube (shaft) with required sizes according to the customer's drawing. It is used to wind up various optical films, copper foils and aluminum foils. It is the first choice of new materials for optical film manufacturing, copper foil manufacturing and aluminum foil manufacturing enterprises.

Advantages of FRP composite core tube (shaft) for optical film, copper foil and aluminum foil

Reduce loss. The FRP composite material core tube has high strength, it is not easy to deform and has stable physical properties. It can prevent damage to the film wrapped due to deformation of the core tube.

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

Large load-bearing capacity. The fiberglass filaments of the FRP composite core tube are cross-wound at large and small angles, which gives the core tube axial and circumferential strength and enables the core tube to have high load-bearing characteristics.

The outer diameter surface of the FRP composite core tube (shaft) can be repaired twice and recycled.

Light weight, 1/4 of the weight compared to similar metal tubes (shafts). The design can save electricity and costs through lightweight design.

It has a wide range of uses and can be used for lithium battery separator copper foil winding core (shaft), PET copper foil winding core (shaft), etc.

Long life, resistant to acid and alkali corrosion, never rust, and free of maintenance.
