Core materials are lightweight structural layers used to create components with a high strength-to-weight ratio. A key part of sandwich panel construction, core materials are bonded between layers of structural composite skins. Separating the skins and ensuring that they cannot move relative to each other provides a significant mechanical advantage and results in very stiff panels with only a minor increase in weight.
The process of separating the structural skins with a core material results in a much lighter structure than solid composite materials would provide. Increasing the core thickness increases the stiffness of the sandwich panel without significantly increasing the weight and cost.
Our range of core materials includes PVC, PET and PMI foam, Nomex and aluminium honeycomb, non-woven fabrics and end-grain balsa wood.
