Dry/Wet Process Prepreg Tow (Single-Filament Prepreg) Production Line

The TT-F-ZC (320~1500)-(1~150) prepreg tow (single-filament prepreg) production line is a dedicated system designed for the production of carbon fiber single-filament prepreg (prepreg tow). The complete line consists of creel, fiber spreading, low-viscosity impregnation, metering squeeze, high-viscosity coating, impregnation, hot-plate drying, cooling, release liner unwinding, release liner rewinding, PE film unwinding, pull-roll, finished-product winding, online width inspection, and electrical control units. The finished product can be either continuous fiber coils (wound on spools) or chopped fibers (cut to length), meeting different downstream process requirements.
The line is suitable for both dry and wet process production of carbon fiber single-filament prepreg, capable of simultaneous production of 1 to 150 tows. It accommodates creel widths from 320 to 1500 mm to meet various capacity needs. The products are widely used in gas cylinder winding, carbon-ceramic composites, pipe winding, automated fiber placement, 3D printing, and other fields, providing high-quality prepreg tow feedstock for downstream composite parts, ultimately serving high-end manufacturing sectors such as rail transit, photovoltaic new energy, automotive, semiconductor, and marine industries.

·Production Modes: 1–150 tows simultaneously (dry/wet process)
·Effective Width: 320–1500 mm (optional)
·Heating Methods: Thermal oil, electric heating
·Finished Product Forms: Continuous coil or chopped fiber
·Application Fields: Gas cylinder winding, carbon-ceramic composites, pipe winding, automated fiber placement, 3D printing, etc.

·High-Precision Control
Dual-servo control for winding and traversing. Traverse width and winding pattern are freely set via HMI. Tension control uses floating-rod constant tension with high stability and accuracy. Fiber unwinding uses magnetic powder brake with closed-loop constant tension control.
·Customized Fiber Spreading Design
Unique fiber spreading and width-limiting devices ensure consistent tow width and straightness of the finished product.
·Intelligent System
Full-line servo control with centralized HMI for automatic control of metering/impregnation roll gap, tension, speed, temperature, length, and other parameters. Each unit can also be operated independently on-site.
·Multi-Function, Flexible Production
Can produce 1 to 150 tows simultaneously as needed. Supports both wet and dry prepreg processes. Optional film or release liner covering. Finished product can be continuous coils or chopped fiber, adapting to downstream processes such as winding, compression molding, and injection molding.
·Modular Expandable Design
Creel width (320~1500 mm) and number of tows (1~150) are customizable. PE film narrow-unwind and finished-winding stations can be expanded to meet various capacity requirements.
·Wide Application Range
Suitable for dry/wet carbon fiber single-filament prepreg production, widely used in gas cylinder winding, carbon-ceramic composites, pipe winding, automated fiber placement, 3D printing, and more.
