50% Long Carbon Fiber Reinforced Nylon 6 (LFT-G® PA6-CF50)
LFT-G® PA6 CF50 is a high-performance long-fiber reinforced polyamide 6 (LCF-PA6) that offers superior structural strength and stiffness performance compared to conventional short-fiber PA6 CF50. This apex composite, reinforced with 50% long carbon fiber in a tough Nylon 6 matrix, is engineered for the most demanding applications where maximum stiffness-to-weight ratio is the primary design driver. It is the ultimate thermoplastic solution for replacing metals like aluminum and magnesium in critical components. In short, this page details an engineering solution for ultimate lightweighting and performance (LFT-G® PA6 CF50-BC05B) - blending the peak structural power of 50% long carbon fiber with the strength and thermal resistance of a Nylon 6 matrix, ideal for next-generation motorsport auto parts, aerospace components, and professional sporting goods.
Q: What is carbon fiber nylon 6 used for?
A: High-end applications where maximum strength and minimum weight are critical. This includes structural auto parts for motorsport, lightweight aerospace components, industrial robot arms, and professional sporting goods like bicycle frames and hockey sticks.
Q: How does 50% carbon fiber affect performance?
A: A 50% loading of long carbon fiber creates the stiffest and strongest possible injection-moldable nylon composite. It results in a material with a modulus that can exceed 27,000 MPa, delivering truly metal-like rigidity for applications that cannot tolerate any flex or vibration.
Q: Is LFT a good alternative to thermoset carbon fiber?
A: Yes, for many applications. While thermosets may offer slightly higher ultimate properties, LFT (Long Fiber Thermoplastic) offers significantly faster production cycles (injection molding vs. hand layup), greater design freedom for complex parts, and much higher impact resistance (toughness). It is the ideal choice for high-volume, high-performance components.
Navigating the Material Universe: Where LFT-G® PA6-CF50 Dominates
LFT-G® PA6-CF50 uniquely occupies the top-right quadrant, establishing it as the only material that combines elite, near-thermoset performance with the speed, design freedom, and cost-effectiveness of high-volume injection molding.
Case Study: Aerospace Cabin Bracket
The Challenge
An aerospace interior supplier needed to redesign a structural bracket for an overhead luggage bin. The existing part was machined from 7075 aluminum. While strong, it was heavy, and the multi-axis machining process was extremely slow and expensive, creating production bottlenecks. The challenge was to find an injection-moldable composite that could match the stiffness and load-bearing capacity of the aluminum part while offering significant weight and cost savings.
The Solution: LFT-G® PA6-CF50
Our 50% long carbon fiber Nylon 6 composite was the only thermoplastic that could meet the stringent performance targets. Its immense modulus provided the rigidity to handle the specified load case with minimal deflection, passing all cyclic fatigue tests. By leveraging injection molding, we were able to consolidate features and create a complex, net-shape part in a single shot, completely eliminating the need for CNC machining. The part was also inherently corrosion-resistant and electrically conductive, aiding in static dissipation.
Result: A 50% lighter bracket that met all aerospace structural requirements, with an 80% reduction in per-part production cost and a 95% faster cycle time.

Application Deep Dive: Where Ultimate Performance is Required
Motorsport Suspension Components
Engineering Problem: Suspension arms and uprights must be incredibly stiff to maintain precise wheel geometry under extreme cornering loads, and as light as possible to reduce unsprung mass.
Why LFT-G® PA6-CF50 Excels:
- Ultimate Modulus: Provides the rigidity needed to function as a direct replacement for machined aluminum.
- Vibration Damping: The composite structure naturally dampens high-frequency vibrations from the track surface.
- Impact Resistance: Far more resistant to catastrophic failure from track debris or contact than brittle thermosets.
High-End Drone Chassis
Engineering Problem: Professional cinematography and heavy-lift drones require a chassis that is absolutely rigid to eliminate camera vibration and support heavy payloads, while being feather-light to maximize flight time.
Why LFT-G® PA6-CF50 Excels:
- Peak Stiffness-to-Weight: Delivers the highest possible rigidity for the lowest possible weight in a thermoplastic.
- Part Integration: Allows for the molding of complex, aerodynamic chassis with integrated mounts in a single part.
- Durability: Tougher and more resilient to hard landings and crashes than typical carbon fiber plates.
