Type 4 Cylinder Winding Machine
Introduction to Type IV Hydrogen Storage Cylinders
Type IV hydrogen storage cylinders feature a fully-wound fiber-reinforced structure with non-metallic liners, offering advantages such as lightweight design, high hydrogen storage density, and extended service life. These cylinders are widely used in hydrogen fuel cell vehicles.
Structural Composition (from inner to outer layers):
| Liner | Made of thermoplastic polymers (PA6, PA11, HDPE, etc.) |
| Intermediate layer | Carbon fiber-reinforced polymer (CFRP) |
| Outer layer | Glass fiber-reinforced polymer (GFRP) |
Manufacturing Process Overview
The production of Type IV cylinders primarily involves composite materials processing, valve integration, regulator installation, and assembly inspection. The key manufacturing stages include:
1. Liner Production: Forming thermoplastic polyolefin polymers into cylindrical liners
2. Fiber Winding Process: Automated fiber reinforcement application
3. Testing & Assembly: Quality verification and component integration
