LFT-G® PEEK CF30 is a high-performance engineering plastic reinforced with 30% long, continuous carbon fibers. Unlike standard short-fiber compounds, its unique long fiber structure creates a three-dimensional reinforcement network within the PEEK matrix. This results in a material that delivers exceptional strength, superior fatigue resistance, and unmatched dimensional stability under extreme loads and temperatures.

When short-fiber PEEK isn't enough, upgrade to PEEK LCF30. Its long carbon fiber structure provides superior resistance to cracking, creep, and wear-extending part life in high-stress environments and reducing downtime.
🔬 Microstructure Comparison
PEEK LCF30's long fiber reinforcement specifically combats crack propagation and material fatigue, offering proven reliability where standard reinforced plastics fail.
Short Fiber Reinforced PEEK
Isolated Reinforcement Points
Analogy: Like adding gravel to concrete-not only limited in its hardness-enhancing effect but also unable to resist tearing and splitting.
❌ Fiber Distribution: Scattered, randomly oriented short segments
❌ Stress Transfer: Interrupted at fiber ends, cracks propagate easily
Analogy: Like embedding a precise steel mesh in concrete-not only hard but also possessing exceptional crack resistance and overall toughness.
✅ Fiber Structure: Continuous, intersecting, long fiber network
✅ Stress Transfer: Effectively dispersed and borne by the fiber network
✅ Performance: Excellent impact and fatigue resistance
✅ Failure Mode: Resists cracks effectively and extends its lifespan.

How is LFT-G® PEEK LCF30 Manufactured? | The Long Fiber Production Process
Intro
Our PEEK LCF30 (30% Long Carbon Fiber Reinforced PEEK) pellets are made via a streamlined, high-precision process to ensure consistent fiber dispersion and mechanical strength. Here's our core production flow:
Step-by-Step Production
1. Fiber Roving Prep: Premium fiberglass rovings are unwound and aligned for uniform distribution, critical for maintaining 30% long carbon fiber loading in PEEK LCF30.
2. Polymer Melting: Virgin PEEK resin + performance additives are melted in an extruder to create a homogeneous thermoplastic melt, optimized for fiber bonding.
3. Impregnation (Core Step): Fibers are saturated with molten PEEK in an advanced impregnation die, ensuring full coating and a precise 30% fiber-to-resin ratio for PEEK LCF30.
4. Pulling & Cooling: The composite strand is pulled to maintain tension, then cooled to solidify the matrix and preserve the 11mm fiber length that defines PEEK LCF30 performance.
5. Granulation: The solid strand is cut into 0.5" / 11mm PEEK LCF30 pellets, ready for downstream injection molding or extrusion.

Challenge: A manufacturer of high-temperature industrial pumps needed to replace a critical metal seal and bearing component. The original part failed quickly due to extreme heat (over 200°C / 390°F) and constant friction, causing frequent downtime and high maintenance costs.
Solution:
The component was redesigned and injection molded as a single piece using LFT-G® PEEK LCF30. This material was chosen for its unique combination of strength, heat resistance, and natural lubricity.
LFT-G® PEEK LCF40 Verification Results:
70% Longer Service Life: The PEEK LCF30 part lasts significantly longer than the metal version, reducing unplanned downtime.
50% Weight Reduction: The lighter component decreases system inertia and improves pump efficiency.
High-Temperature Performance: It operates continuously above 220°C / 430°F without loss of performance or deformation.
FAQ
What is the wear resistance of LFT-G® PEEK CF30?
A: LFT-G® PEEK CF30 offers excellent wear resistance and a low friction coefficient, ideal for high‑cycle moving parts without external lubrication.
What is the difference between LFT-G® PEEK LCF30 and PEEK CF30?
A: LFT-G®PEEK LCF30 uses long carbon fibers for higher impact strength, fatigue and creep resistance compared to short‑fiber CF30, making it better for structural and dynamic applications.
Can LFT-G® PEEK CF30 replace metal in load-bearing parts?
A: Yes. PEEK LCF30 matches or exceeds the specific strength (strength-to-weight ratio) of aluminum and some steels, while offering added benefits like corrosion resistance, inherent lubricity, and the ability to be molded into complex geometries in a single part.
