T1100-grade carbon fiber is a high-performance carbon fiber material whose research, development, and engineering mass production have been achieved through industry-university-research collaboration between domestic universities and enterprises. Its density is approximately one-quarter that of steel, while its tensile strength reaches up to 7,000 MPa, making it seven times stronger than high-strength steel.
In 2023, domestic universities and enterprises began collaborating to tackle the challenge of large-scale production of T1100-grade carbon fiber. Through over thirty cycles of iteration between “laboratory and production line,” the two parties successfully reduced the void ratio in the precursor filament—a key defect affecting performance—by approximately 60%. By September 2025, they achieved stable mass production of T1100-grade carbon fiber on a fully domestically produced thousand-ton production line, with the product yield rate consistently exceeding 95%.
Performance Parameters
T1100-grade carbon fiber boasts a tensile strength of up to 7,000 MPa, a tensile modulus of 324 GPa, and a single filament diameter of only about 5 micrometers. Its density is merely one-quarter that of steel, yet its strength is equivalent to seven times that of high-strength steel. A vivid example is that just 0.3 grams of this material can support the weight of three adults.
The material is now produced reliably on a fully domestic thousand-ton production line, with batch yield rates exceeding 95%.
Technical Characteristics
T1100-grade carbon fiber features a single filament diameter of only about 5 micrometers, a tensile strength of up to 7,000 MPa, and a tensile modulus of 324 GPa. Its density is only one-quarter that of steel, while its strength is seven times greater.
In terms of application, T1100-grade carbon fiber presents an “interface treatment” challenge. Due to its surface being as smooth as glass, bonding it with other materials is extremely difficult. Through extensive testing, the domestic research team has preliminarily completed the technological reserve for interface treatment at the laboratory stage and is now moving to validate its effectiveness on enterprise production lines.
Looking ahead, the collaborative partners plan to adopt a strategy integrating “materials genome engineering + AI + technical processes + equipment” for ongoing research and development. The goal is to stabilize the performance of T1100-grade carbon fiber and its composites, while focusing efforts on developing fourth-generation ultra-high-performance carbon fiber (T1200 grade) and new-generation ultra-strong and tough carbon fiber composite technologies.
Application Fields
Domestic T1100-grade carbon fiber is one of the materials used for primary load-bearing structures in domestic large passenger aircraft. It has successfully completed on-site sampling from three batches and aviation application evaluation tests at Commercial Aircraft Corporation of China (COMAC). In the field of sporting goods manufacturing, domestic high-end carbon fiber has been applied in Olympic and Asian Games-level equipment such as bicycles and rackets, achieving batch supply. In the 3C electronics sector, related products have also entered the precision structural component validation phase for major brands. When domestic T1100-grade carbon fiber is used in equipment like aircraft and high-speed trains, its interface treatment technology, having completed laboratory-stage reserve, will now enter the validation phase on enterprise production lines.
