Gillfab® 4009

Overview

Gillfab® 4009 is a light weight and highly strength sandwich panels made from uni-directional carbon fiber reinforced epoxy facings bonded to Gillcore® HD 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)
