Carbon or graphite fibres

In thermoplastics, carbon fibre is particularly used in reinforcement of nylon, where a 30% (by weight) fibre content will increase flexural strength by about three times, and flexural stiffness may be increased by a factor of seven. Electrical properties, friction behaviour, and wear resistance may also be improved. 

Electrical applications fall into two categories to impart conductivity, to prevent build-up of electrostatic discharge (which may cause short circuits, or
