Wholesale Japanese Mitsubishi Original HR40 12M Carbon Fiber Yarn PYROFIL 12K Carbon Fiber Yarn

Product Name: Mitsubishi Chemical High Modulus Carbon Fiber – HR40 12M

Headline: The Perfect Combination of Exceptional Stiffness and Processability

The Mitsubishi HR40 12M is a high-modulus PAN-based carbon fiber tow specifically engineered for high-performance composite materials. This grade achieves an ideal balance between rigidity and strength, combining an excellent tensile modulus of 40 tf/mm² (approx. 375GPa) with a high tensile strength. The 12K (12,000 filaments) configuration offers superior handling characteristics for Automated Fiber Placement (AFP), Automated Tape Laying (ATL), and various weaving processes. It is the material of choice for aerospace, high-end industrial components, and sporting goods where ultimate lightweighting and structural rigidity are critical.

Key Advantages & Features

1. Superior Mechanical Properties:

   • High Modulus Design: With a tensile modulus of 375 GPa, it provides exceptional resistance to deformation, ensuring high dimensional stability in structural parts under load.
   • Retained High Strength: Exhibiting a tensile strength of over 4400 MPa, it offers excellent load-bearing capacity to withstand complex and demanding stress environments.

2. Excellent Processability (12K Format):

   • Low Fuzz Level: Advanced surface treatment technology minimizes fuzzing, ensuring smooth running in weaving and prepreg processes, thereby reducing downtime.
   • Good Bundle Integrity: The tow is flat and smooth, facilitating easy spreading and impregnation, making it ideal for manufacturing high-quality prepregs and 3D fabrics.

3. Compatibility & Consistency:

   • Engineered Sizing: Features a specialized sizing agent optimized for compatibility with thermoset matrices like Epoxy and Bismaleimide (BMI) resins, ensuring strong fiber-to-matrix interfacial adhesion for full property realization
   • Batch-to-Batch Stability: Manufactured under Mitsubishi Chemical's stringent quality control, ensuring consistent performance across all lots for reliable large-scale industrial application.

Technical Data

Typical Applications

• Aerospace: Primary structural components (wings, fuselage panels), secondary structures, and satellite antenna booms.
• Industrial Equipment: High-stiffness robotic arms, high-speed drive shafts, pressure vessels, and medical imaging bed panels.
• High-End Sports & Leisure: Competition bicycle frames, golf club shafts, fishing rods, tennis rackets, and snowboards.
