Material
Carbon Fiber PETG
Carbon fiber PETG is a reinforced composite that adds significant stiffness and dimensional stability to standard PETG, trading some impact resistance for rigidity. It is ideal for parts that need to hold their shape under load.
Manufacturing processes
About
Carbon fiber PETG is a composite made by blending standard PETG with chopped carbon fiber, typically 10-20% by weight.
The fibers substantially increase stiffness – tensile modulus can run several times higher than standard PETG – along with better dimensional stability under load. This comes with a real trade-off, though: Despite being stiffer, carbon fiber PETG is generally more brittle and has lower impact resistance than standard PETG, which makes it a weaker choice for parts that need to absorb sudden shocks or drops. It does retain PETG's resistance to moisture and many common chemicals.
Carbon fiber PETG is well suited to jigs, fixtures, drone frames, and mounting brackets that need to resist bending or flexing under load.
