PEEK, 30% carbon filled
Polyetheretherketone
Carbon-reinforced PEEK for wear resistance and electrical conductivity.
30% carbon fiber gives PEEK higher stiffness than the natural grade along with genuine wear resistance and a measure of electrical conductivity that glass fiber doesn't provide. It's the grade to specify for sliding or rotating wear surfaces.

Handling notice
- PEEK, 30% carbon filled carries residual stress from how the plate was made. Cutting it free lets that stress release, and a 12x12 blank can bow 0.010-0.025 in within 48 hours. Stress-relief annealing is available at quote time.
Why this material
Choose carbon-filled PEEK over glass-filled when the part actually slides or rotates against another surface, or when static dissipation matters. Its self-lubricating tendency is the real differentiator from GF30.
Typical applications
- Bearing and bushing surfaces under continuous wear
- Components requiring static-dissipative or conductive properties
- Aerospace and semiconductor parts needing high stiffness-to-weight
- Pump wear rings and thrust washers
Handling notes
- Carbon fiber dust is electrically conductive and can be more aggressive on tooling than glass fiber - dedicated blade handling applies.
Questions
Is carbon-filled PEEK conductive?
It's static-dissipative to semi-conductive depending on loading and part geometry - enough to matter in electronics handling applications, though it's not a substitute for a metal in a true conductor role.
Carbon-filled or glass-filled PEEK for a wear part?
Carbon-filled, in almost every case. Its lower coefficient of friction and better wear performance are the reason this grade exists.
Does the carbon fiber affect edge finish options?
Similarly to glass fiber - expect a slightly rougher as-cut edge than natural PEEK. Deburring and chamfering are unaffected.
