40% Long Carbon Fiber Reinforced Nylon 6 (LFT-G® PA6-CF40)
This is the new standard in structural composites. Our LFT-G® PA6-CF40 is an advanced composite that combines a high-performance Nylon 6 (PA6) matrix with a high 40% loading of long carbon fiber. It is engineered to deliver an extraordinary stiffness-to-weight ratio, providing a superior, lightweight alternative to metals like aluminum in the most demanding applications. In short, this page details an engineering solution for ultimate lightweighting and performance (LFT-G® PA6-CF40-BC04B) - blending the structural power of 40% long carbon fiber with the strength and thermal resistance of a Nylon 6 matrix, ideal for next-generation structural auto parts, industrial robotics, and professional sporting goods.
Q: What is PA6 CF40?
A: LFT-G® PA6 CF40 is an advanced composite with a Nylon 6 matrix, reinforced with 40% long carbon fiber. This combination creates an exceptionally stiff, strong, and lightweight material used for structural auto parts and high-performance industrial components.
Q: How does PA6 Carbon Fiber compare to Aluminum?
A: LFT-G® PA6-CF40 offers a superior stiffness-to-weight ratio. It can match the rigidity of many 6000-series aluminum alloys at up to 50% less weight. Additionally, it offers better vibration damping, corrosion resistance, and the ability to mold complex parts in a single step, reducing production costs.
Q: What are the limitations of carbon fiber nylon?
A: The primary considerations are its electrical conductivity, which must be managed in electronic applications, and the inherent moisture absorption of the Nylon 6 matrix. While minimal, moisture can affect dimensional stability, so this should be accounted for in the design of high-precision parts. Our engineering team can provide detailed guidance on this.

Case Study: Industrial Robotic Arm
The Challenge
A leading industrial automation company was designing a new generation of high-speed collaborative robots ("cobots"). To increase speed and payload capacity, the structural arm of the robot needed to be as lightweight and stiff as possible. Lower weight reduces inertia, allowing for faster acceleration and safer operation around humans. Higher stiffness reduces deflection and vibration at the end of the arm, ensuring greater precision. The current design used machined aluminum, which was heavy and expensive.
The Solution: LFT-G® PA6-CF40
Our 40% long carbon fiber Nylon 6 composite was the ideal material to push the performance envelope. Its extraordinary modulus provided the required rigidity to ensure the robot's movements were precise and repeatable to sub-millimeter accuracy. The material's low density enabled a 50% weight reduction in the arm structure compared to the aluminum design. Furthermore, the material's inherent vibration damping properties helped to quickly stabilize the arm after fast movements, reducing cycle times.
Result: A 50% lighter robotic arm that was 15% faster and more precise, with a 40% lower manufacturing cost per unit.

Application Spotlights: Solving Engineering Challenges
Automotive Sunroof Frames
The Challenge: Large panoramic sunroof frames must be extremely rigid to prevent flexing and ensure a proper seal, but also lightweight to avoid raising the vehicle's center of gravity.
The Solution: A single-piece, injection-molded frame using LFT-G® PA6-CF40 to replace a heavy, multi-part steel or aluminum assembly.
The Result: A 50% lighter frame with improved torsional stiffness, reduced assembly steps, and a streamlined supply chain.
Professional Camera Tripods
The Challenge: The legs and central hub of a professional tripod must be exceptionally stiff and absorb micro-vibrations to ensure sharp images during long exposures. Portability demands the lowest possible weight.
The Solution: Molding the structural components from LFT-G® PA6-CF40, leveraging its high modulus and inherent vibration damping properties.
The Result: A tripod that is as stable as its heavier aluminum counterparts but is 40% lighter, with superior vibration damping for clearer photos.
