The prepreg production line consists of two core parts: a coating machine and a laminating machine. It is designed to handle various reinforcements such as carbon fiber, glass fiber, basalt, aramid, and UHMWPE fiber, as well as resin systems including epoxy, phenolic, cyanate ester, and bismaleimide. It can produce prepreg products with widths ranging from 500 to 1275 mm, meeting the precision manufacturing needs of high-end sporting goods, UAVs, automotive and rail transit, wind turbine blades, shipbuilding, 3C electronics, and medical rehabilitation devices.
The TT-Y-GF (300~1600) laminating machine is the core processing unit of the prepreg production line. The complete system consists of creel, fiber spreading, upper/lower carrier film unwinding, upper/lower PE film rewinding, fabric unwinding, impregnation and laminating, hot plates, cold plates, release liner rewinding, PE film unwinding, film covering, pull-roll, edge trimming, cutting, winding, online basis-weight inspection, online defect inspection, and electrical control units. It realizes a fully continuous automated process from fiber spreading, resin impregnation, laminating and setting, to finished roll winding.
·Unique Fiber Spreading Design
Combined vertical and horizontal vibrating spreading unit with independently adjustable frequency and amplitude, meeting the requirements of low-areal-weight, large-tow production. Ensures uniform fiber distribution without gaps or overlaps. Spreading rolls are preheated with thermal oil to soften the sizing agent for easier spreading.
·Ultra-High Precision Laminating Rolls
Roll precision within ±2 μm under working temperature. Servo-controlled nip gap adjustment with measurement accuracy of 0.5 μm and control accuracy of 1 μm. Roll surface temperature accuracy of ±1°C, ensuring consistent lamination quality.
·Precision Lamination Pressure Control System
4 to 7 sets of laminating rolls, each with independent closed-loop gap control, supporting intelligent switching between gap mode and pressure mode.
·Flexible Pressure System Options
Lamination pressure can be provided by pneumatic cylinders, hydraulic systems, or servo systems, adapting to different process requirements.
·Flexible Heating Methods
Laminating roll heating can be via thermal oil or electromagnetic induction heating.
·Full-Line Servo Control
Full-line servo control with centralized HMI for automatic control of nip gap, tension, speed, temperature, length, and other parameters. Each unit can also be operated independently on-site.
·Comprehensive Data Foundation
Extensive sensor network for real-time acquisition of temperature, tension, speed, gap, online basis weight, visual defects, and other process data. Recipe management supports storage and one-click recall of hundreds of complete process parameter sets. Production and quality data are linked to batch numbers, traceable, exportable, and capable of generating quality trend analysis reports. The control system provides standard industrial communication interfaces (Ethernet, OPC UA, Modbus TCP, etc.) for seamless integration with MES or ERP systems.
·Optional Online Inspection Systems
Optional online basis-weight gauge, defect inspection system, and automatic labeling unit to enhance quality monitoring. High-resolution visual defect inspection can identify foreign matter, holes, gaps, resin bleed-out, resin starvation, scratches, and other defects.
