Phenolic Faced Nomex Honeycomb Sandwich Panels - Cellite™ 840

The Cellite™ series of Sandwich Panels have been used for a number of years to design bonded assemblies, composite components, and lightweight structures for the defense, aerospace, marine, motorsports and rail industries. The panels can be machined, fabricated, and assembled into different types of structures for a broad range of applications in many industries.

The special features of the Sandwich Panels are derived from a fusion of facing skins and core, bonded using high-performance adhesive. By tailoring the separate elements to meet distinct conditions, the ensuing benefits can be used for different applications where low weight and high stiffness are specific necessities.
