LFT-G^®PA6 LCF30 High-Temperature Power Train Material

Advanced Thermoplastic Composite

LFT-G Long Carbon Fiber Reinfored Nylon6 PA6 LCF Engineer Plastic Granules

LFT-G^®PA6 LCF30 High-Temperature Power Train Material is a 30% long-carbon-fiber-reinforced polyamide 6 specifically developed for severe-environment under-hood components and powertrain housings. Delivering exceptional heat deflection performance, superior creep resistance, and outstanding dimensional stability under continuous thermal stress, it is available as ready-to-mold pellets that simplify manufacturing and guarantee batch-to-batch consistency.

LFT-G^®PA6 LCF30 integrates the inherent lubricity and chemical resistance of PA6 with a rigid continuous carbon fiber network. Unlike conventional glass fiber compounds, the elongated carbon strands establish a high-strength load-bearing structure that significantly enhances high-temperature rigidity, fatigue life, and abrasion resistance-critical characteristics for engine auxiliary parts, transmission gears, and bearing cages operating under aggressive cyclic loads.

Supplied as uniform, resin-rich plastic pellets, LFT-G^®PA6 LCF30 flows smoothly through intricate molds, enabling complex geometries with ultra-low warpage and excellent surface replication. This high-performance thermoplastic sets a new standard for metal replacement in thermal applications, offering significant weight savings and corrosion immunity without compromising mechanical integrity.

Key Material Characteristics

⚡

Continuous Fiber Reinforcement Architecture

Long carbon fiber reinforcement creates a load-bearing skeleton that efficiently transfers stress throughout the component, delivering metal-like stiffness and strength at a fraction of the weight.

Load-Bearing Skeleton

📐

Exceptional Dimensional Stability and Low Warpage

The long, randomly oriented fibers significantly reduce anisotropic shrinkage, resulting in minimal and predictable part warpage.

Precision Molding for Complex Geometries

💧

Superior Fatigue and Creep Resistance

The entangled fiber network effectively restricts polymer chain movement under sustained load. This grants PA6 LCF30 outstanding resistance to creep deformation.

Long-Term Performance Under Dynamic Stress

🛡️

Enhanced Thermal Performance

Carbon fibers improve the thermal conductivity and stability of the composite. PA6 LCF30 exhibits a high Heat Deflection Temperature (HDT) to maintain structural integrity in high-temperature environments.

High-Temperature Structural Capability

⏳

Excellent Impact Strength and Toughness

The long fibers act as crack arresters, bridging micro-cracks and absorbing impact energy. This results in significantly higher notched impact strength compared to short-fiber grades.

Damage-Tolerant Material Behavior

🎯

Inherent Electrical Conductivity

The interconnected carbon fiber network provides a percolation path for electrical conductivity, resulting in a surface resistivity in the range of 10² Ω/sq. This inherent property eliminates the need for secondary coatings.

Built-In ESD/EMI Shielding Functionality

Key Application Fields

Industrial Drone Propulsion Systems & Airframe Arms

Replacing machined 7075 aluminum in heavy-lift drone motor mounts, propeller hubs, and main airframe arms, PA6 LCF30 delivers equivalent structural stiffness while weighing 45% less. The continuous long carbon fiber network provides exceptional fatigue resistance to withstand thousands of takeoff/landing cycles, while its inherent vibration damping protects sensitive avionics and camera systems. Its corrosion resistance also makes it ideal for marine and agricultural drone applications.

E-Mobility Mid-Drive Motor Housings & Crank Assemblies

Engineered for high-performance electric bicycles and light electric motorcycles, PA6 LCF30 replaces die-cast aluminum in mid-drive motor housings, crank arms, and gear carriers. It maintains the torque capacity required for hill climbing. The material's excellent vibration absorption cuts drivetrain noise by 12dB, and one-piece injection molding eliminates 8 assembly parts, reducing production costs.

Medical Imaging Rotating Gantries & Surgical Robot End Effectors

PA6 LCF30 is the ideal material for non-magnetic components in CT scanners, MRI machines, and surgical robotic systems. Unlike aluminum and steel, it causes no image artifacts in magnetic fields, while its ultra-high dimensional stability ensures precise positioning accuracy within ±0.02mm. The low-inertia design allows faster gantry rotation speeds and smoother surgical robot movements, improving patient throughput and procedure outcomes.

Solar Tracker Drive Mechanism Components

Designed for utility-scale solar power plants, PA6 LCF30 replaces cast iron and steel in solar tracker gear housings, linkage arms, and bearing supports. It reduces component weight by 50%, making installation faster and safer, while its exceptional creep resistance maintains structural integrity under 25 years of continuous wind and thermal loads. The material's natural UV and weather resistance eliminates the need for expensive protective coatings.

FAQ

Q: What is LFT-G^®PA6 LCF30?

A: LFT-G^®PA6 LCF30 is a high-performance engineering plastic consisting of 30% long carbon fiber reinforced polyamide 6 (nylon 6). Produced via a continuous impregnation pultrusion process, it retains full-length fiber networks in molded parts, delivering superior strength, stiffness and impact resistance compared to short fiber reinforced materials.

Q: How to maximize fiber length retention during LFT-G^®PA6 LCF30 injection molding and what percentage can be realistically achieved?

A: Use a low-compression screw (2.0:1-2.5:1), 40-60 RPM screw speed, large gates and <5 MPa back pressure. With proper optimization, you can retain 60-70% of original fiber length, averaging 2.0-4.0mm in finished parts.

Q: Can LFT-G^®PA6 LCF30 regrind be reused?

A: Yes. Use up to 25% regrind for non-critical parts and 10% or less for load-bearing components. Avoid regrind processed more than three times, as excessive fiber breakage will degrade performance.
