Jwell continuous fiber prepreg reinforced composite production line with thermosetting plastic is designed to manufacture high-performance composite materials where fibers are impregnated with a thermosetting resin, such as epoxy, polyester, or phenolic resin. These prepregs are used in various advanced applications, including aerospace, automotive, marine, and sporting goods.
Fiber prepreg composites are made of reinforced fiber materials: glass fiber (GF), aramid fiber (AF), ultra-high molecular weight polyethylene fiber (UHMW-PE), basalt fiber (BF), through yarn laying, traction, yarn spreading , pre-impregnated water-based adhesive or oil-based adhesive, heat curing, winding and other processes to form thermosetting prepreg; prepreg is then staggered and laminated to form a high strength, high modulus, light specific gravity, anti-corrosion, anti-soaking , moisture-proof and other characteristics of prepreg composite materials.
It is in common use PET/ABS/PP/PC/PA/PPS/POM and other kinds of thermoplastic resin matrix materials.

1. Creel Rack:
- Fiber Spools: Holds spools of continuous fibers such as carbon, glass, or aramid.
- Tension Control System: Maintains consistent tension in the fibers to prevent breakage and ensure uniform impregnation.
2. Pre-Heating Station (optional):
- Heating Elements: Pre-heat the fibers to remove moisture and prepare them for impregnation.
3. Resin Impregnation System:
- Resin Bath: The fibers pass through a bath containing the liquid thermosetting resin.
- Resin Film Coater: An alternative method where a thin film of resin is applied to the fibers.
4. Blades or Metering Rollers:
- Blades: Control the resin content by scraping off excess resin from the fibers.
- Metering Rollers: Ensure uniform resin distribution across the fiber width.
5. Heat Tunnel or Curing Oven:
- Partial Curing (B-Stage): The impregnated fibers pass through a controlled heating system to partially cure the resin, giving the prepreg the required tackiness and handling properties.
6. Cooling Zone:
- Cooling Rollers or Air Cooling: Cools the partially cured prepreg to a manageable temperature for further processing.
7. Compaction Rolls:
- Compaction Rollers: Compress the prepreg to remove air bubbles and ensure uniform thickness and resin distribution.
8. Release Paper Application:
- Release Paper or Film: Applied to one or both sides of the prepreg to prevent sticking and protect the material during handling and storage.
9. Slitting Unit:
- Rotary Knives or Slitting Blades: Cut the prepreg into the required widths for different applications.
10. Winding Unit:
- Roll Winder: Collects the finished prepreg onto rolls for storage and transportation.
- Tension Control: Ensures even and tight winding of the prepreg.
11. Control System:
- PLC (Programmable Logic Controllers) and HMI (Human-Machine Interface): Monitors and controls various parameters of the production process, such as tension, temperature, resin flow rate, and speed, to ensure consistent product quality.
12. Quality Control and Inspection Station(optional but recommended):
- Sensors and Imaging Systems: Inspect the prepreg for uniformity, defects, and other quality parameters.
1. Fiber Preparation: Continuous fibers are fed from the creel rack, ensuring consistent tension and alignment.
2. Impregnation: The fibers pass through a resin bath or are coated with a resin film. The resin is distributed evenly across the fibers, typically using doctor blades or metering rollers.
3. Partial Curing: The impregnated fibers pass through a heat tunnel or curing oven where the resin is partially cured (B-stage). This gives the prepreg enough tackiness for easy handling while ensuring that it is not fully hardened.
4. Cooling and Compaction: The prepreg is cooled and passed through compaction rollers to remove air bubbles and ensure uniform thickness and resin distribution.
5. Release Paper Application: Release paper or film is applied to the prepreg to protect it and prevent sticking.
6. Slitting: The prepreg is slit to the required width using rotary knives or slitting blades.
7. Winding: The finished prepreg is wound onto rolls for storage and transportation, with tension control to ensure even winding.
8. Quality Control: Continuous monitoring and inspection ensure the prepreg meets the required specifications and quality standards.
