Nylon 66 Thermoplastic Plastics Long Carbon Fiber Plastic Compounds

What Is Pa66 LCF?

Our PA66 (Polyamide 66) composite reinforced with continuous long carbon fibers (LCF) delivers exceptional mechanical strength, superior stiffness, excellent wear resistance, and outstanding thermal stability. Engineered for high-performance applications requiring lightweight structural parts with excellent dimensional stability, fatigue endurance, and long-term durability.

Technology Behind the Strength
Continuous Long Carbon Fiber Reinforcement
Unlike short fiber composites, our PA66-LCF materials feature long carbon fibers (typically 12–25 mm) carefully oriented and embedded during compounding and molding. This continuous fiber network forms a rigid internal skeleton that significantly boosts tensile strength, flexural modulus, impact resistance, and fatigue life, far surpassing short fiber counterparts.

Advanced Compounding & Pultrusion Techniques
Using precision pultrusion and compounding processes, the long carbon fibers are uniformly dispersed within the PA66 matrix with excellent fiber-matrix adhesion and minimal fiber breakage. This ensures consistent mechanical properties, high repeatability, and stable performance across production batches.

Excellent Thermal Resistance & Wear Properties
The PA66 polymer matrix provides high heat deflection temperatures, excellent abrasion resistance, and good chemical resistance to fuels, oils, and many solvents, making it suitable for components operating under high load and elevated temperatures.

Superior Dimensional Stability and Creep Resistance
The synergy between PA66’s inherent toughness and long carbon fiber reinforcement results in low thermal expansion, high rigidity, and outstanding creep resistance — essential for precision parts exposed to sustained mechanical loads and thermal cycling.

Where It Works Best
