我国量产地表超强材料，单丝直径不到头发丝十分之一

Group 1 - The domestic T1000-grade high-performance carbon fiber has been developed, featuring 12,000 filaments per strand, with a weight of only 0.5 grams per meter and tensile strength exceeding 6,600 MPa, making it 7 to 8 times stronger than steel [1] - This breakthrough signifies a leap from T300 to T1000 in domestic carbon fiber production, addressing the "bottleneck" issue in high-end materials and providing strong momentum for the upgrade of high-end manufacturing during the 14th Five-Year Plan [1] Group 2 - The high-performance carbon fiber industry in China is at a critical transformation point, shifting from meeting domestic demand to participating in global high-end competition, with a projected capacity exceeding 250,000 tons by 2030, accounting for over 50% of global demand [2] - The usage of carbon fiber in the new energy vehicle sector is expected to increase from 5% to 20%, with the demand in this sector projected to represent 45% of total demand by 2030, making it the largest single application area [2] - The low-altitude economy in China is expected to exceed 1 trillion yuan by 2026, leading to a surge in carbon fiber demand from core carriers like eVTOL and drones [2] Group 3 - Relevant A-share concept stocks include Zhongjian Technology and Guangwei Composites [3]
