Polyamide 6/6 - Nylon 6/6 - PA 6/6 30% Carbon Fibre Reinforced

May 16 2001

Polymer Type

Thermoplastic

Advantages

Extremely low coefficient of thermal expansion, good wear properties, excellent stiffness and strength, high thermal conductivity, high electrical conductivity (could also be a disadvantage depending upon application) and extremely low creep when compared with unmodified polyamide 6/6.

Disadvantages

Properties can be highly anisotropic dependant on processing conditions. Expensive compared to glass reinforced grades. Not as tough as glass grades. Natural colour of carbon-reinforced grades is black.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
