Sandwich Panels

Current Incorporated manufactures structural sandwich panels designed for use in interior applications for mass transit, marine, infrastructure and commercial aviation.

Structural sandwich panels consist of three basic elements: a pair of thin lightweight, strong facings; a lightweight core to separate the two facings; an attachment that is capable to transmitting shear and axial loads to and from the core.

Qualified to BMS 4-20, Mil-STD-401B and FAR 25.853 fire resistance. Some of Currents’ structural panels have been designed to offer superior flame resistance, high-temperature performance along with low toxicity and smoke characteristics.

  • Facings: Consist of woven glass, carbon fiber uni tapes or aluminum. Face sheets provide the required bending an in-plane shear stiffness to carry the axial, bending and in-plane shear loading.
  • Adhesives: Standard epoxy and phenolic films; two part systems and a modified epoxy film designed to meet the FAA flame spread requirements are used in the construction of structural sandwich panels.
  • Resin Systems: Epoxy and phenolic.
  • Core: Aramid Honeycomb, aluminum and foam. The primary function of core material in a structural sandwich panel is that of stabilizing the facings and carrying most of the shear loads through the thickness. In order to perform this job efficiently, the core must be as rigid and as light as possible, and must deliver uniformly predictable properties in the environment.

Material is available in standard 48” x 96” and 48” x 120”sheets. Other sizes available upon request
