Material
Carbon Fiber PEEK
Carbon-reinforced PEEK is stiffer and somewhat stronger than normal PEEK, with a much higher heat deflection temperature under load, though it is far less ductile.

About
Carbon-reinforced PEEK is PEEK filled with chopped carbon fibers (about 20%), making it roughly 2.5 times stiffer than unfilled PEEK and somewhat stronger. Heat deflection under load rises from about 152 °C to over 300 °C, while the glass transition (143 °C) and melting point (343 °C) stay the same. The trade-off is ductility: elongation falls from about 45% to about 2%, so parts are rigid but brittle.
Carbon-reinforced PEEK is a good option for rigid, high-temperature structural parts and tooling.
