Applications: Where LFT-G® PA6 CF30 Delivers
Automotive Lightweighting
Replace metal and short-fiber composites in seat structures, pedal carriers, and battery frames. LFT-G® PA6 CF30 delivers up to 40% weight reduction while withstanding underhood fluids and dynamic loads-ideal for EV and high-performance vehicles.
Industrial Machinery & Robotics
Precision components like robotic arms, grippers, and conveyor modules demand dimensional stability. The long carbon fiber network minimizes creep and warpage, ensuring repeatable accuracy in high-cycle automation.
Sports & Leisure Equipment
From bicycle frame inserts to ski bindings and protective gear, this material offers the strength-to-weight ratio athletes demand. High energy absorption prevents catastrophic failure on impact.
FAQ
Q: What's the difference between LFT-G® PA6 CF30 and short-carbon-fiber PA6?
A: Long carbon fibers (6–25 mm) create an interconnected network that delivers superior impact resistance, higher energy absorption, and better creep performance than short-fiber compounds-even those with higher filler content.
Q: Can LFT-G® PA6 CF30 replace metal in structural parts?
A: Yes. With a strength-to-weight ratio approaching aluminum, up to 40% weight savings, and excellent chemical resistance to oils and greases, it's a proven drop-in replacement for machined or die-cast metal components-without corrosion or secondary operations.
Q: What industries commonly use this material?
A: Automotive (lightweight brackets, pedal carriers), industrial robotics (grippers, arms), and sports equipment (bicycle parts, protective gear)-anywhere stiffness, weight reduction, and fatigue endurance are critical.
