Module 6. Materials & hardware

Kevlar and Nomex are types of

  • glass fibre composite.
  • advanced composite.
  • aluminium alloy.

Explanation

Kevlar and Nomex are aramid materials, used as high-strength aramid fibre and as honeycomb core respectively, and are classed as advanced composites. They are not glass-fibre products and are organic polymers, so they are not aluminium alloys.

Boydonnelly asking:

Please explain to me the difference between. Glass fibre opposite and a advanced composite ?

Kevlar and Nomex are not a glass fiber. Glass fiber just little part of the advanced composites. Kevlar and Nomex are synthetic polymers, and glass fiber is synthetic mineral.

In addition I'd like to say what fiber glass is simple, cheap material, widely used in many industries, so it is not advanced.
But Kevlar and Nomex are aramid based materials, which are used in aerospace and military applications. These materials are pretty expensive.
