Carbon Fiber

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.

Intermediate modulus (IM) carbon fibers exhibit a tensile modulus of 42 Msi. Originally developed for aerospace applications, IM fibers now find use in recreational and industrial applications as well. Toray offers a broad range of IM fibers with a mix of price and performance characteristics to meet the needs in a broad range of industries. Toray’s IM fibers are available in 6K, 12K, and 24K tow sizes.

• T800H – An intermediate modulus, high tensile strength fiber, with high level and balance composite properties. Designed and developed to meet the weight saving demands of aircraft applications. Is used in primary structure of commercial aircraft, including vertical fin and horizontal stabilizers. Available in 6K and 12K tow sizes.
• T800S – A cost-effective intermediate modulus fiber with higher tensile strength compared to T800H. This never-twisted fiber has especially high tensile properties. Is used extensively in primary structure of commercial aircraft. Available in 12K and 24K tow sizes.
• T1000G – A high tensile strength carbon fiber. Suitable for lightweight, tensile strength critical applications such as pressure vessels for aerospace vehicles, and satellites, as well as hydrogen storage tanks for fuel cell vehicles. Available only in a 12K tow size.
• T1100G – Next-generation intermediate modulus fiber with excellent processability in high-performance manufacturing methods such as weaving, prepreg, etc. Available in 12K and 24K tow sizes.
• T1100S – Next-generation intermediate modulus fiber with excellent processability and enhanced performance in demanding manufacturing methods such as filament winding. Available in 12K and 24K tow sizes.

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.
