Standard Modulus Carbon Fibers

About Standard Modulus

Standard modulus carbon fibers typically exhibit a fiber modulus of 33-34 Msi or slightly higher. These are the most cost-effective fibers as measured by tensile strength or modulus per unit cost. Toray’s T300 standard modulus carbon fibers are a recognized industry standard, having been in production since 1971. T700S is a high tensile strength, standard modulus carbon fiber which is another standard industrial fiber. Standard modulus carbon fibers are available in tow sizes from 1K to 24K.

• T300 – Baseline carbon fiber used in aerospace applications with over 20-year service history. Has 30-year production history and is known for balanced composite properties, high quality and consistency, reliability and availability of supply. Available in 1K, 3K, 6K and 12K tow sizes.
• T700S – An industry standard fiber for high strength and standard modulus, with outstanding processing characteristics for filament winding, weaving and prepregging. This never-twisted fiber is used in a variety of industrial and recreational applications, including pressure vessels such as natural gas vehicle (NGV) storage tanks and SCBA breathing tanks. Available in 6K, 12K, and 24K tow sizes.
• T700G – Enhanced tensile modulus and adhesion properties over T700S. Applications of this never-twisted fiber include aircraft and high-performance sporting goods where demanding conditions require superior composite properties. Available in 12K tow sizes.

High Modulus Carbon Fibers

About High Modulus

Toray’s MJ and M-series high modulus carbon fibers represent the highest modulus PAN-based carbon fibers available. PAN-based high modulus fibers are superior to pitch-based fibers due to tensile and compressive strengths that are often times more than twice that of a corresponding pitch-based fiber. The MJ series fibers offer enhanced tensile strength and elongation over M series fibers. They are typically used in stiffness and coefficient of thermal expansion (CTE)-critical applications such as spacecraft, premium sporting goods and industrial rollers.
