What is PA6 LCF30 material?
LFT‑G® PA6 LCF30 is a long carbon fiber-reinforced polyamide 6 composite. It bridges the gap between high-performance engineering plastics and metals – offering structural integrity where standard short-fiber materials fall short. It delivers long-fiber performance without the processing headaches of continuous fiber tapes. And it does so with the consistency that only a true injection molding compound can provide.

Long Carbon Fiber Advantage
LFT-G® PA6 LCF30 vs. PA6 CF30
LFT‑G® PA6-LCF30 (30% long carbon fiber) vs. PA6-CF30 (30% short carbon fiber). At an identical 30 wt% carbon loading, the long-fiber architecture provides significantly enhanced stiffness, tensile strength, and impact resistance.
Key Industry Uses
🚁
Aerospace & UAV Structural Components
Drone arms, airframe brackets, camera gimbal mounts, and payload connectors. PA6 LCF30 delivers ultra‑high stiffness and vibration damping in an extremely lightweight package – critical for flight stability and endurance. Its long carbon fiber network resists micro‑cracking under repetitive flight loads, enabling thinner, stronger designs that outperform short‑fiber or even aluminum alternatives.
🤖
High‑Performance Robotics & Automation
Robot arm links, end‑effector tool plates, joint housings, and lightweight gripper jaws. PA6 LCF30 provides the precise rigidity required for high‑speed pick‑and‑place operations while absorbing shock loads without permanent deformation. The material's exceptional fatigue life and dimensional stability keep joints calibrated over millions of cycles – a key advantage over glass‑filled or metal components.
🏎️
Competition & Electric Vehicle Chassis Systems
Battery housing structural inserts, suspension links, anti‑roll bar brackets, and pedal box assemblies. PA6 LCF30 offers metal‑equivalent stiffness at less than half the density, directly improving vehicle dynamics and range. Its long carbon fiber architecture delivers controlled failure modes and high impact resistance – essential for safety‑critical chassis parts in EVs and motorsport applications.
FAQ
Q: What makes long carbon fiber different from glass fiber in PA6?
A: Carbon fiber delivers significantly higher stiffness and strength at lower density. Long-fiber architecture further enhances impact and fatigue resistance – something glass fiber cannot match.
Q: Is PA6 LCF30 sensitive to moisture like unreinforced PA6?
A: The long carbon fiber reinforcement – at 30% loading – substantially reduces the hygroscopic effect. Water absorption is lower than unfilled PA6, and more importantly, the dimensional and mechanical property changes are minimized.
Q: Can PA6 LCF30 be molded on standard injection molding equipment?
A: Yes. Use a general-purpose screw, avoid excessive back pressure, and opt for wider gates to preserve fiber length – no special machine required.
