Carbon Fiber Tow / Yarn / Roving: Superior Processability
Benefits of Sizing
Protects filaments, improves abrasion resistance, enhances spreadability and significantly improves processing efficiency for downstream composite manufacturing.
No Negative Impact on Resin Wettability
Suitable for epoxy, vinyl ester, phenolic, and thermoplastic resin systems.
No Fraying & Excellent Package Formation
Sized tow maintains perfect bundle integrity during high-speed unwinding and processing.
Production Environment Control
The weaving workshop maintains constant temperature and humidity.
Stabilized/Set Carbon Fiber Fabric: Unique Shape Stability
The adhesive spraying process of JiLin Carbon Fiber Fabric is our distinct feature, providing excellent shape retention capabilities suitable for composite applications requiring high stability. This stabilized design further reinforces the performance stability of our carbon fiber cloth under extreme conditions.
