Why composite materials work so well
As with the principles that make a steel I-beam so strong, it is the outside faces of a composite that does most of the work when the sheet is subject to bending, so separating these faces makes for efficient use of the material.
For a composite to be most effective:
- The core needs to have good compression resistance and shear strength.
- The skin material needs to have a high modulus and tensile strength.
- The adhesive bond of skin to core is critical for maintaining composite performance.
Composites: A sustainable choice
This efficient use of materials means less raw materials are needed to create high performance sheets.
Coretinium derives its performance from the high quality pre-finished steel skins
The high strength of steel
The high Young’s modulus of steel makes it a very effective skin material compared to other options:
The other benefits of steel
Steel offers some significant benefits over other traditional skin materials:
- Durable – UV resistant skin.
- Fire safe – A1 non-combustible.
- Resistant to creep.
- Easy to process on CNC.
- Easy to mechanically fix to.
- Strong stable surface for adhesive.
* With typically 85% of product weight coming from the Coretinium® steel skins; at its end-of-life the composite sheet can be considered as steel scrap and recycled back into the steel making process without the need to separate the core from the skin.
