As more and more composite structures require unique bends and curvatures, Ultracor has introduced UltraFlex. UltraFlex is available as a honeycomb core with distinctive cell geometry. UltraFlex provides similar or higher mechanical properties than comparable hexagonal cores of equivalent density.
The table below compares the mechanical properties of the UltraFlex and the hexagonal core using the same prepregged material.
|Compressive ASTM C365||Plate Shear ASTM C273|
|Stabilized||L Direction||W Direction|
|Ultracor Product Code||Construction Type||Strength (psi)||Modulus (ksi)||Strength (psi)||Modulus (ksi)||Strength (psi)||Modulus (ksi)|
Note: Although the UltraFlex cell is non-symmetric, the W-shear properties showed similar results regardless of shear direction.
