Advanced Composite Sandwich Panels

A sandwich panel is generally composed of two thin but stiff facing skins separated by a comparatively thicker, low density core material such as foam or honeycomb. The separation of the skins by a lightweight core acts to dramatically increase the second moment of area and therefore the bending stiffness. A familiar analogy is that of the metal ‘I’ beam where flanges top and bottom are separated by a vertical (shear web). This effect is illustrated below:

At Juno Composites, we construct the skins and core from a range of materials to satisfy performance, weight and cost requirements of your application. For instance we can manufacture bespoke sandwich panels containing carbon, glass, Kevlar skins, foam or honeycomb cores and even create hybrid panels that incorporate a combination of these materials.

The sandwich panels manufactured by Juno Composites Ltd are a fantastic material that have numerous characteristics that make them attractive for many applications particularly in the transport sector, including:

• High specific stiffness and strength compared with other types of panel materials e.g. steel, wood and glass. Making sandwich panels the pinnacle choice for lightweighting, which in turn leads to enhanced
performance of you vehicle or vessel and/or lower life cycle costs.

•Durability – Juno Composites sandwich panels will never rot or corrode.

• Design integration – our panels combine numerous functionalities including excellent mechanical performance particularly stiffness, thermal insulation not to mention an extraordinary aesthetics that cannot be replicated with other materials.

• Excellent surface quality (“flatness”) compared to stiffened plates.

• Good crashworthiness performance.

• Excellent vibration damping properties.

• Reduced assembly and installation time and overheads.
