LFT-G® PA6 CF40 (LCF40) Black – Aerospace-Grade Structural Nylon
While standard chopped CF40 is brittle, our pultrusion technology preserves 10-12mm fiber lengths. This structural mesh absorbs extreme shock, acts as an integrated EMI/RFI shield, and provides unparalleled fatigue life at a hyper-lightweight density of just 1.28 g/cm³.
The Truth About CF40: Why Fiber Length Matters
Many engineers source standard PA6 CF40 without realizing it uses milled or chopped fibers (<1mm). See why upgrading to our Long Carbon Fiber (LCF40) prevents catastrophic part failure.
- • Fibers are too short (<1mm) to transfer stress.
- • Highly brittle; shatters easily under sudden impact.
- • Inconsistent electrical conductivity.
- • Poor long-term fatigue endurance.
- • 10-12mm continuous fiber network.
- • 3X higher impact strength; absorbs crash energy.
- • Continuous EMI/RFI shielding grid.
- • Survives millions of vibration cycles.

Hyper-Performance Applications
EV Battery & ECU EMI Housings
Electric vehicle control units (ECUs) require strict electromagnetic shielding. The 40% carbon network in this carbon fiber PA6 creates an impenetrable Faraday cage, completely eliminating the need for expensive secondary metal foil spraying while providing 26 GPa crash protection.
UAV & Aerospace Frames
In aerospace, minimizing mass is the primary directive. With a density of just 1.28 g/cm³, LCF40 replaces heavy aluminum and expensive thermoset carbon fiber layups. It allows drone manufacturers to injection-mold highly complex, rigid chassis structures in seconds.
Frequently Asked Questions (FAQ)
Q: If I am currently using PA6 CF40, why should I switch to LCF40?
A: Standard PA6 CF40 uses chopped fibers, making the part extremely brittle and prone to shattering under impact. Our Long Carbon Fiber (LCF40) technology maintains 10mm fiber lengths. This structural mesh acts as a shock absorber, multiplying the impact strength by 3X while maintaining the same 26 GPa stiffness.
Q: Does the 40% carbon loading cause excessive mold wear?
A: Carbon fiber is highly abrasive. We mandate the use of hardened tool steel (HRC 55+) for molds and bimetallic screws/barrels for your injection machines. Standard P20 steel molds will degrade rapidly. Our technical team will provide comprehensive DFM support to protect your tooling.
Q: Can LCF40 be used as an EMI Shielding material?
A: Yes, intrinsically. With a surface resistivity of 10² - 10³ Ω, the continuous 40% carbon network forms a highly conductive Faraday cage inside the plastic part. It blocks electromagnetic and radio-frequency interference (EMI/RFI) without any secondary metal plating.
