CBZ® for carbon composites
-
Why use CBZ® ?
Rapid cycle time
Significant reduction in processing time and thermal energy usage can be achieved by using CBZ®.
- Example
- VaRTM in room temperature curing
-
Light weight design
By using CBZ®, lighter composites
can be designed.Example of CF laminates

High strength
Room temperature cured CBZ®, even non-post cured, can provide better mechanical properties than 3hrs post cured standard vinyl ester resin.
