LFT-G® PA6 LCF40 40% Long Carbon Fiber Nylon 6 Compound
LFT-G® PA6 LCF40 (Model: LFT-G® PA6 LCF40-BC04B) represents the absolute peak of high-modulus thermoplastic performance. By combining a highly crystalline polyamide 6 matrix with 40% continuous long carbon fibers through automated pultrusion technology, this structural compound yields a breathtaking tensile modulus exceeding 30,000 MPa. It is explicitly designed for extreme industrial applications requiring definitive metal replacement.
Standard chopped PA6 CF40 compounds suffer from localized brittleness and internal fiber degradation during injection shearing. In contrast, our premium long carbon fiber composite matrix retains a long-strand internal 3D structural network. This continuous carbon skeleton distributes complex mechanical loads uniformly, ensuring maximum structural integrity, low density, and permanent dimensional stability under severe environmental stress.
The Metalloid Threshold: Standard PA6 CF40 vs. LFT-G® PA6 LCF40
Many procurement projects search for standard PA6 CF40 only to face brittle failures. See how upgrading to our continuous long carbon fiber network redefines industrial part boundaries.
Standard PA6 CF40 (Short Carbon Fiber Alternative)
❌ Discontinuous Core Linkage:
- Short chopped fiber fragments act as severe stress focal points.
- Brittle behavior under unexpected dynamic impact or sudden loading.
- Severe structural warping and anisotropic shrinkage during processing.
- Structural Reliability: COMPROMISED
LFT-G® PA6 LCF40-BC04B (Continuous Long Carbon Fiber Matrix)
✅ Cohesive 3D Carbon Skeleton:
- Interconnected long strands route structural loads seamlessly.
- Over 2.5x the impact resistance of short-fiber composites.
- Uniform shrinkage behavior eliminates structural assembly warping.
- Structural Reliability: OUTSTANDING

Frequently Asked Questions (FAQ)
Q: Why choose PA6 LCF40 over standard PA6 CF40 for structural components?
A: The crucial differentiator is internal fiber aspect ratio. Standard short-fiber PA6 CF40 utilizes fractured, short strands that struggle to transfer dynamic loads effectively. LFT-G® PA6 LCF40 maintains a continuous 3D overlapping carbon matrix, which improves impact retention by 250% and delivers an outstanding 28,500 MPa tensile modulus.
Q: Does the 40% long carbon fiber nylon loading cause injection processing challenges?
A: While a 40% loading increases melt viscosity, it processes easily on conventional machinery by applying minor parameter updates. We advise lowering back pressure below 50 psi and using low-compression screws. This safeguards the long carbon fiber alignment, ensuring the final molded parts reach their full mechanical rating.
Q: Can LFT-G® PA6 LCF40 replace structural die-cast Zinc or Aluminum?
A: Unquestionably. With an engineering flexural modulus of 26,000 MPa, LFT-G® PA6 LCF40-BC04B achieves functional rigidity levels that match die-cast alloys. It eliminates expensive CNC machining cycles and structural post-treatments, while significantly reducing total component weight by up to 60%.
