LFT Material

What is PA66 LCF40?
LFT-G® PA66 LCF40 is a special type of polymer that is blended with long carbon fibers, resulting in its excellent strength, stiffness, and impact resistance superior mechanical and thermal properties. This high-performance material is widely used in various industries, from automotive to aerospace.
Key Properties of PA66 LCF40
- The addition of long carbon fibers to nylon 66 greatly improves its mechanical properties, such as tensile strength, flexural modulus, and impact resistance. Compared to unfilled nylon 66, PA66 LCF40 has up to 40% higher stiffness and up to 90% higher strength, making it an ideal material for demanding applications that require high performance and durability.

Advantages of LFT long fiber composite
Extremly Mechanical Properties
Keep longer glass carbon fiber,the LFT long fiber composite will provide higher stiffness strength,high modulus, thoughness than short fiber reinforced material
Strong dimensional durability
LFT long fiber composite is made of high-strength fiber materials such as high-flow Polypropylene/Nylon , which greatly improves its durability and strength.
Excellent Chemical Corrosion
LFT Composite choose multi matrix resin from PP to PEEK,Very good corrosion and chemical resistance Retains performance across low and elevated temperatures


Due to its exceptional mechanical properties, PA66 LCF40 is widely used in many industries, such as:
- Automotive: PA66 LCF40 is commonly used in automotive parts that require high strength and stiffness, such as bumper beams, air intake manifolds, engine covers, and oil pans.
- Aerospace: PA66 LCF40 is also used in aerospace applications, such as structural parts for aircraft and space vehicles, due to its high strength-to-weight ratio and resistance to temperature extremes.
- Industrial: PA66 LCF40 is used in various industrial applications, such as machinery parts, power tools, and electrical components, due to its excellent mechanical and thermal properties.
