Sandwich Cores

Sandwich Cores: High-Efficiency Solutions

A sandwich-structured composite is a special class of composite material, fabricated by bonding two thin but rigid skins to a lightweight, thick core. The core is typically of low strength; however, its thickness provides the sandwich with high bending stiffness and low overall density.

Foam structures, both open and closed cell, such as polyvinyl chloride (PVC), polyurethane, polyethylene, or polystyrene foams, balsa wood, syntactic foams, and panels are common core materials. In some cases, the honeycomb structure is filled with other foams for added strength. Open and closed-cell metal foams are also used as core materials.

Thermoplastic laminates of glass or carbon fiber reinforcement, or thermoset polymers (unsaturated polyesters, epoxy resins, ...) are widely used as skin materials.

The core is bonded to the skin with a specialized adhesive.
