DIAB advanced core materials, when used with high strength skins, provide the ideal combination of strength, stiffness and toughness. DIAB structural cores and composites sandwich solutions work by increasing the performance of composite parts while optimizing weight.
In principle a sandwich consists of two skins or facings with a core material in between. The skins take up normal stresses and give the structure a hardwearing surface. The core material absorbs the shear stresses generated by loads, distributing them over a larger area.
Compared to single skin laminates, the sandwich concept offers substantial improvements in both flexural rigidity and flexural strength. By doubling the thickness of the core, the improvements are even greater yet the weight increase is negligible.
