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

    Matrix resin Convenstional
    epoxy resin
    CBZ 500LM-AS
    Load resistance required [N] 857
    Load of break point [N]
    (bending test)
    863 875
    Thickness of CF laminate [mm] 3.17 2.84
    CF laminate weight
    (2m×8m panel) [kg]
    71.5 63.6
    Weight reduction [%]   -11.0

    CF laminate thickness was designed based on flexural strength.

  • High strength

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