Core Materials


Core materials are used in sandwich construction where structural skins are bonded on either side of a core.  The type of core, skin type and skin thickness all contribute in various ways to the great strength and stiffness of this type of construction.

Core materials are often used where high performance and lightweight is required, such as in aircraft, kayaks and rowing skills.

Core Types include:
Density rated in kg per cubic metre (kg/m³)

Core Cell – Styrene acrylonitrile – linear structural foam – a little more expensive, but top shelf. 80kg/M³ sheets 3mm, 5mm, 8mm, 10mm and 12mm stocked all other thicknesses available on request.

Rigid Polyurethane Foam – 35kg/M³ – 25mm and 50mm sheets stocked. Other thicknesses available on request.

Core Mat – Cheap but soaks up a lot of resin.  3mm available

Balsa – Usually end grain but also used long grain. Is available but not stocked.
