What is carbon fiber nylon: long carbon fiber nylon66 compound.
A carbon fiber nylon 66 composite is a high-performance engineering thermoplastic created by reinforcing a Polyamide 66 (PA66 or Nylon 66) matrix with carbon fibers (CF). PA66 itself is a robust polymer known for its high strength, excellent thermal stability, and superior wear resistance. When infused with carbon fibers-renowned for their extreme stiffness and low density-the resulting composite achieves a level of performance far beyond that of unreinforced plastics. This combination makes carbon fiber nylon 66 a sought-after material for lightweight structural components.
However, the ultimate capability of this composite is determined by the length of the carbon fibers. LFT-G® PA66 CF30 represents the cutting edge, utilizing Long Carbon Fiber Technology (LFT). Unlike conventional Short Carbon Fiber (SCF) composites, the "long fiber" in LFT-G® PA66 CF30 (a 30% long carbon fiber nylon) forms an integral, interlocking 3D skeletal network within the PA66 matrix. This LCF structure is paramount for maximizing mechanical properties, delivering vastly superior impact strength, exceptional fatigue endurance, and metal-like stiffness at a fraction of the density. This positions LFT-G® PA66 CF30 as a premier choice for replacing metals like aluminum and steel in the most demanding applications.

Core Advantages of Carbon fiber Nylon
LFT-G® PA66 CF30 is engineered as a transformative metal replacement solution. The key to its superior performance lies in the 30% long carbon fibers that form an interconnected, skeletal network within the robust Polyamide 66 matrix. This structure is fundamentally better at dissipating energy and distributing stress compared to the random dispersion of short fibers. For your applications, this unlocks the following core advantages:
- Exceptional Specific Strength & Stiffness (Strength-to-Weight)
- Extreme Rigidity & High Flexural Modulus
- Significant Lightweighting for Viable Metal Replacement
- Superior Fatigue & Creep Resistance Under Load
- Outstanding Dimensional Stability & Very Low CTE
- High Heat Resistance and Thermal Stability
- Tunable Electrical Conductivity for ESD/EMI Shielding
- Excellent Wear & Abrasion Resistance

Frequently Asked Questions (FAQ)
Q: Is carbon fiber nylon stronger than aluminum?
A: It depends on how you measure "strong". While high-strength aluminum alloys can have a higher absolute tensile strength, LFT-G® PA66 CF30 exhibits a superior specific strength (strength-to-weight ratio). This means for the same weight, a part made from our long carbon fiber nylon 66 can be significantly stronger and stiffer than an aluminum part, making it a powerful choice for lightweighting without compromising performance.
Q: How long does it take for CF nylon to dry?
A: Nylon (Polyamide) is hygroscopic and must be dried before injection molding to prevent processing issues and ensure optimal part properties. For LFT-G® PA66 CF30, a typical recommendation is to dry the pellets for 4-8 hours at 80-120°C (176-248°F) to reduce moisture content to below 0.2%. Exact times can vary based on initial moisture level and drying equipment.
