Carbon-fibre reinforced polyamide occupies the top of our performance ladder. Short carbon fibres dramatically raise stiffness and specific strength while adding electrical conductivity — a combination impossible to achieve with glass or mineral fillers. The result is a structural material that can directly replace aluminium and zinc die-castings at a fraction of the weight.

Advantages
- Does not accumulate fatigue microcracks — exceptional cyclic-load endurance
- Electrical conductivity eliminates static buildup and RF interference
- Highest specific strength of all PA composites — replaces metals directly
- Wide operating temperature range without dimensional drift
- Low coefficient of thermal expansion close to metals — better fit retention
- Low friction and outstanding wear resistance in dry conditions
- Excellent surface finish for visible structural parts
Technical Note: Carbon vs Glass
Carbon fibre gives roughly 3× the stiffness and 2× the strength of an equivalent glass-filled grade, at only marginally higher density. Its conductivity makes it uniquely suitable for ESD-sensitive environments. Glass-filled grades remain preferred when cost is the primary driver.
