REINFORCED
PPA-CF
A carbon-fibre reinforced polyphthalamide used for strong, rigid and heat-resistant FDM components requiring excellent dimensional stability under demanding mechanical and environmental conditions.
Material Overview
PPA-CF is a carbon-fibre reinforced polyphthalamide thermoplastic developed for high-performance FDM applications. The semi-aromatic polyamide matrix provides strong thermal, chemical and creep resistance, while carbon-fibre reinforcement increases stiffness, mechanical strength and dimensional stability. Compared with conventional nylon materials, suitable PPA-CF grades generally absorb less moisture and retain their properties more effectively in humid or elevated-temperature environments. Final performance depends on the selected formulation, carbon-fibre content, moisture condition, geometry, print orientation, chamber conditions and production parameters.
APPLICATION
Typical Part Types
High-load brackets, mounts and structural supports
Machine components exposed to elevated operating temperatures
High-temperature jigs, fixtures and manufacturing tools
Automotive under-bonnet mounts and non-safety-critical functional components
Electrical and electronic housings requiring heat and dimensional stability
Robotic structures, gripper components and equipment interfaces
Bearing housings, guides and mechanically loaded interfaces
Pump, valve and fluid-handling components following chemical compatibility review
Lightweight industrial components requiring a high strength-to-weight ratio
Strong one-off parts and controlled production runs for demanding service conditions
Material Selection Note
PPA-CF is suitable where high stiffness, mechanical strength, heat resistance, creep resistance and dimensional stability are required simultaneously. It should not be treated as moisture-proof, fully isotropic or equivalent to metal. Printed performance remains dependent on fibre direction, layer bonding, wall design, chamber conditions and moisture control. Gramm reviews the carbon-fibre grade, applied load, operating temperature, humidity, chemical exposure, print orientation, geometry and dimensional requirements before manufacturing.
