Manufacturing Technology Overview
1. Fiber Creel System
The manufacturing process begins with controlled feeding of continuous E-glass fiber rovings from multi-position creel stations with precise tension control and fiber alignment.
2. Fiber Pre-Forming and Alignment
Engineered guide systems organize and compact fiber bundles to achieve optimized fiber volume fraction and controlled orientation.
3. Resin Impregnation System
Fibers enter a specially designed resin bath using high-performance thermoset resin systems including vinyl ester and epoxy formulations.
4. Pull-Winding Surface Formation Technology
Continuous axial fibers provide longitudinal strength while helically wound fibers create engineered surface deformation for improved concrete bonding.
5. Controlled Thermal Curing System
The composite passes through a temperature-controlled curing oven where complete polymerization occurs to achieve final strength, thermal stability, and chemical resistance.
6. Continuous Pulling System
A synchronized pulling mechanism continuously draws the composite through the production line ensuring stable dimensional accuracy and production consistency.
7. Automated Cutting and Finishing
Finished GFRP rebars are automatically cut to specified lengths and undergo final inspection to ensure dimensional precision and quality compliance.
Quality Control & Process Monitoring
Fiber Volume Fraction Control
Maintains optimal fiber-to-resin ratio for maximum tensile performance and structural reliability.
Dimensional Accuracy
Continuous monitoring verifies diameter tolerances, straightness, and surface geometry consistency.
Mechanical Performance Testing
Finished rebars undergo tensile strength, bond performance, shear, and durability testing.
