Graphite / Titanium Honeycomb

Titanium honeycomb core advantages in graphite bonded structures

 

Benecor titanium surface preparation process enhances panel bond strengths

Impact damage modes by skin design: Damage modes:
Benecor's titanium surface enhances panel strength Impact side - very visible (local damage)
Internal - core crushing (no disbonds)
Back side - no damage
Impact side - barely visible
Internal - foam crushing & disbond
Back side - no visible damage
Impact side - barely visible
Internal - delaminations
Back side - no visible damage
