Flexible carbon fiber decorative veneer
A flexible carbon fiber decorative veneer may include a veneer panel assembly with a face layer formed from a carbon fiber material, a backing layer formed from a flexible fleece, and an adhesive configured to attach the face layer to the backing layer through activation via at least one joining process. The backing layer may be configured to prevent light from passing through voids or interstitial spaces in the carbon fiber material of the face layer when the backing layer is attached to the face layer via the adhesive. The flexible carbon fiber decorative veneer may be configured for use on an aircraft interior structure, the base structure for which being fabricated from an aviation honeycomb layer and a back panel. The veneer panel assembly may be configured to conform to a radius of at least 0.25 inches on the aircraft interior structure.
