Gillfab® 4009

Overview

Gillfab® 4009 is a light weight, high strength sandwich panel made with uni-directional carbon fiber reinforced epoxy facings bonded to Gillcore® HD meta-aramid honeycomb.

 

Applications

The panel is designed for use as medium duty structural panels in aircraft, where light weight and rigidity are primary considerations, such as underseats, galleys, flooring, and bulkheads.

Features

  • Light weight and high rigidity
  • Glass fiber overlay can be added to prevent galvanic corrosion
  • Service temperature up to 160°F (71°C)
