The Unidirectional (UD) Impregnation Tape Line is a high-performance composite production system designed to manufacture continuous fiber-reinforced thermoplastic tapes. It uniformly impregnates aligned continuous fibers (such as carbon fiber or glass fiber) with molten thermoplastic resin to produce high-strength, lightweight composite tapes with precise thickness and fiber volume control.
This unit features uniform fiber spreading, minimal fiber damage, controllable process temperatures, high production efficiency, precise control of fiber content and surface density, and uniform product thickness, etc.
These UD tapes are widely used as intermediate materials for lightweight structural components in automotive, aerospace, wind energy, pressure vessels, and construction industries.
Production Process
Fiber creel → Fiber spreading → Preheating → Resin extrusion → Impregnation & calendering → Cooling → Edge trimming → Haul-off → Online thickness inspection → Winding
Process Features:
1.Continuous fiber spreading system ensures uniform filament distribution
2.Precision extrusion system for stable resin output
3.High-pressure impregnation rollers ensure full wet-out
4.Accurate thickness control via servo-driven calendering system
5.Online tension control system for stable tape quality
6.PLC centralized control for fully automatic operation
