Composite materials

Why composite materials

Composite materials are structural materials that consist of two components – a reinforcement material and a thermosetting resin system. The two components are cured under pressure and high temperature into a finished material. The reinforcement materials and thermosetting resin systems can be combined in various ways facilitating the manufacture of composite materials with very different properties. Therefore, composite materials are attractive and versatile alternatives to other structural materials.

High strength, low weight

High pressure composite materials warrant stable geometry at high temperatures and have minimal movement and deformation when subjected to loads. In addition, they exhibit high strength/weight ratio (the density is approx. one-fifth that of steel and half that of aluminium). It is also important to note that high pressure composite materials have properties that do not deteriorate with age.

Numerous areas of application

Composites were originally used as insulation materials in electro-technical designs. Today, modern composite materials are used in a wide range of industries and only the imagination sets the limits for what can be done.

From the medical to the aerospace industry

Originally used as insulation materials in electro-technical designs, composites are now used in a wide range of sectors and industries – from the medical to the aerospace industry.

Mechanical applications:

  • engineering materials
  • wear parts and glide surfaces

Electrical applications:

  • electrical insulation
  • engineering materials

Examples of mechanical applications:

Guides rings for hydraulic cylinders:

  • prevents metal to metal contact e.g. between piston and cylinder, and absorbs high transverse loads
  • high wear resistance in aggressive and dusty environments
  • can be lubricated with water, oil or grease

Ball bearing cages for high-speed ball bearings:

  • low weight, high strength
  • reduces centrifugal forces, noise and wear

Examples of electrical applications:

Electrical insulation for train transformers:
