GillVANA® 4809G

Overview

GillVANA® 4809G is a damped sandwich panel made from unidirectional carbon fiber reinforced epoxy facings bonded to GillVANA® honeycomb core. The para-aramid / phenolic honeycomb core is coated with GillVANA® resin containing a damped material to provide acoustic benefits, while still meeting physical, mechanical and flammability requirements. Outer panel surfaces feature fiberglass overlay to help protect against galvanic corrosion.

The United States Patent #10,933,605.

Applications

GillVANA® sandwich panels are ideally suited for commercial passenger aircraft flooring, sidewalls and ceiling panels delivering a weight-efficient solution of vibration and noise attenuation.

Features

Excellent acoustic properties
Good impact strength
Excellent machinability and bonding surfaces
Resistant to galvanic corrosion
Excellent strength-to-weight and stiffness-to-weight ratios
Very light-weight and negligible panel deflection under load
