PAHT-CF Carbon Fiber Nylon overview
Stiff, lightweight carbon fiber nylon for parts that would otherwise be machined from metal. Parts hold their shape under load up to 170 °C, weigh less than half as much as the same part in aluminum, and resist most oils and greases. Teams use it for jigs, fixtures and drill guides, robot grippers and end-of-arm tooling, brackets and full-scale sports equipment prototypes.
How PAHT-CF Carbon Fiber Nylon is manufactured
PAHT-CF Carbon Fiber Nylon is manufactured using Fused Deposition Modeling (FDM) on Bambu Lab H2D and H2S printers, whose hardened steel nozzles handle the abrasive carbon fiber while actively heated chambers build parts layer by layer with no tooling. Parts are annealed after printing as part of the process, which raises their strength, heat resistance and dimensional stability. FDM takes this composite from functional prototypes to jigs, fixtures and short-run end-use parts.

Industry applications
Industry applications for PAHT-CF Carbon Fiber Nylon
PAHT-CF Carbon Fiber Nylon enables metal replacement strategies for brackets, fixtures and structural components. With tensile strength of 92 MPa and a flexural modulus of 4.2 GPa along the layers, it delivers the rigidity demanding applications need in a lightweight composite.
Because the carbon fiber reinforcement makes it anisotropic, engineers orient parts for their specific load cases. From rapid prototyping to production runs, teams rely on PAHT-CF Carbon Fiber Nylon to maintain tight tolerances while reducing assembly complexity through consolidated part designs.
Resistance to most oils and greases, a 170 °C heat deflection temperature and low moisture absorption suit it to under-hood brackets and fixtures and to industrial equipment that needs both rigidity and environmental durability.
Aerospace and motorsport teams use it where low weight drives the design. Aerospace programs print lightweight tooling, UAV structural frames and ground support equipment, while racing teams iterate aerodynamic winglets and vanes, brake cooling ducts, structural brackets and custom driver controls, with design changes printed overnight between sessions. The same low weight suits film crews building lightweight structural props and rigid frames for hero props.

Industrial Automation
Robot Cell Flexure Springs
Welding automation builders use carbon fiber nylon for flexure springs that combine a thin spring leaf with mounting bosses and through-bores, reordered in lots of a few to a few dozen with no tooling. Because the drawing fixes the recipe, from solid fill to the long edge on the bed, and the order names a hardened nozzle, every lot is set up and checked against the same specification. Critical bores print undersize and are reamed to their limits after a first article confirms shrinkage, and most dated lots in the program shipped one to two days early.

- Robot cell brackets and guards
- Cable guides
Robotics
End-of-Arm Tooling & Brackets
Automation teams use PAHT-CF Carbon Fiber Nylon for gripper fingers and jaws, end-of-arm tooling structures and vision system brackets. Its low mass reduces inertia, so robot arms accelerate faster and cycle times drop. At a density of 1.06 g/cm³, an end effector weighs less than half as much as the same part in aluminum.
- Gripper fingers and jaws
- End-of-arm tooling structures
- Vision brackets and cable management
Automotive
Line-Side Tooling & Machining Fixtures
Vehicle and electric motor lines use PAHT-CF Carbon Fiber Nylon for drill guides, soft jaws and assembly fixtures, where stiffness is critical for precisely locating the workpiece. Printed tools replace heavier machined tooling and hold their shape under a 1.8 MPa load up to 170 °C, so fixtures near hot processes stay accurate.

- Soft-jaw machining fixtures
- Assembly fixtures and gauges
Industrial Design
Full-Scale Product & Sports Equipment Prototypes
Product teams print full-scale prototypes of sports equipment, outdoor gear and mobility products in PAHT-CF Carbon Fiber Nylon, because it gives them the structural performance for load testing and real-world validation. Bicycle components and brackets, equipment handles and grips, and performance measurement housings print in the same composite, and parts larger than the build envelope are sectioned and assembled with integrated joinery.

Mechanical performance
Mechanical properties
PAHT-CF Carbon Fiber Nylon delivers high tensile strength and rigidity for aerospace brackets and mounts, automotive structural parts and robotic end-of-arm tooling, so prototypes are tested in the same material that goes to production.
FDM parts are strongest along their layers, and the carbon fiber makes the difference larger than in unfilled nylon. X-Y values come from specimens printed along the build plate and Z values from upright specimens loaded across the layers, so orient loaded features along the build plane and size parts against the Z figures. Elongation at break is low, so size flexing features such as spring leaves for small deflections.

Heat performance
Thermal properties
Heat deflection is measured at two loads, and both sit far above the glass transition temperature, so parts keep their shape under load well above room temperature. Parts are annealed after printing, which raises crystallinity, heat resistance and dimensional stability.
The Vicat softening and melting temperatures mark where the material softens and melts, so size loaded parts for their real service temperature against the heat deflection values.

Chemical properties
PAHT-CF resists most oils and greases, which suits fixtures and brackets around machinery and vehicles. Acids, alkalis and some organic solvents attack it, so keep it away from cleaning chemicals and process fluids in those groups.

Frequently Asked Questions
Frequently asked questions about PAHT-CF Carbon Fiber Nylon

- PAHT-CF Carbon Fiber Nylon is a carbon fiber reinforced, nylon 12-based composite. Along the layers (X-Y) it reaches 92 MPa tensile strength, 125 MPa flexural strength and a 4.23 GPa flexural modulus, and its heat deflection temperature of 170 °C at 1.8 MPa (194 °C at 0.45 MPa) keeps aerospace tooling and automotive fixtures in shape in hot environments. Forge anneals parts after printing as part of the process.
- PAHT-CF Carbon Fiber Nylon is printed by Fused Deposition Modeling (FDM) on Bambu Lab H2D and H2S printers with hardened steel nozzles and actively heated chambers, in parts up to 340 × 320 × 340 mm, then annealed. It is used for jigs, fixtures and drill guides, robotic end-of-arm tooling, structural brackets and functional prototypes that would otherwise be machined in metal.
- PAHT-CF Carbon Fiber Nylon is used across aerospace, automotive, robotics, manufacturing and sporting goods for drill guides and soft-jaw fixtures, gripper fingers and end-of-arm tooling, flexure springs for robot cells, UAV frames and ground support equipment, motorsport brackets and ducts, and bicycle components.
- PAHT-CF Carbon Fiber Nylon combines high rigidity with low weight: at a density of 1.06 g/cm³ it is less than half the weight of aluminum for the same volume. It resists most oils and greases, absorbs only 0.88% moisture at saturation (25 °C, 55% relative humidity), and holds a 170 °C heat deflection temperature under a 1.8 MPa load.
- PAHT-CF Carbon Fiber Nylon is anisotropic: upright (Z) parts reach 47 MPa tensile strength against 92 MPa along the layers, so orientation matters, and elongation at break is 8.4% along the layers and 4.1% upright. It is black only, has no flame-retardant rating, and acids, alkalis and some organic solvents attack it. It needs hardened steel nozzles and costs more than standard thermoplastics.
- Yes, for tooling, functional prototypes and short-run parts. PAHT-CF Carbon Fiber Nylon is less than half the weight of aluminum for the same volume, but aluminum remains stiffer and stronger in absolute terms, so the best swaps are drill guides, soft jaws, fixtures, end-of-arm tooling and brackets where low weight and fast iteration matter more than peak load.
