Toho Tenax HTA40 1K is a standard modulus, high-strength PAN-based carbon fiber tow manufactured by Teijin, a global leader in carbon fiber production. It belongs to the general-purpose series within Teijin's product line and is widely used as reinforcement in various composite materials due to its stable performance and excellent processability.
Product Features:
- Standard Modulus: With a tensile modulus of 240 GPa, it offers a good balance of stiffness and cost-effectiveness.
- High Strength: It provides reliable mechanical properties with a tensile strength of 4100 MPa .
- Fine Tow: This specific grade is 1K, meaning each bundle contains 1000 individual filaments, classifying it as a small tow carbon fiber. This fine tow is ideal for processes requiring good spreadability and drapability, such as weaving and braiding. It is commonly used to manufacture thin-walled, lightweight, and structurally precise composite components, including high-end sporting goods, medical equipment, and industrial robot arms.
- Sizing Treatment: Standard products are typically treated with an epoxy-compatible (EP) sizing, with a content of approximately 1.3%-2.5%, designed to protect the fibers and improve their wettability with the resin matrix during processing.
