What do the numbers Toray T700 T1000 mean?

Toray is a world-renowned materials science company, the full name of Japan Toray Co., Ltd. The carbon fiber produced is characterized by light weight, high strength and high stiffness. The T series is their high-performance carbon fiber product. T refers to the tensile tonnage that this type of carbon fiber can withstand with a cross-sectional area of one square centimeter. The larger the T value, the greater the tensile strength.

Common grades from low to high are T300, T700, T800, and T1000. T300 and T700 are standard modulus carbon fibers, with high tensile strength and moderate modulus, providing good strength and stiffness, and relatively light weight. They are often used in entry-level carbon fiber road cars. T800 is a medium modulus carbon fiber, which is slightly higher than T700 in strength, has a higher wear rate, and can provide higher stiffness at a lighter weight, but the cost is also relatively high, and is often used in mid-to-high-end road cars. T1000 is an ultra-high-strength medium-grinding carbon fiber with very high tensile strength and abrasion, extremely high strength and rigidity, and the lightest weight. It meets the production requirements of the aerospace field and is often used in ceiling-level road bikes of various brands #Carbon Fiber Wheels #Carbon Fiber
