Materials form the physical foundation of human existence and serve as strategic pillars for national economic development. Technological advancements drive increasing performance demands, accelerating innovations in glass fiber, carbon fiber, graphite fiber, and their composites. With over 92% carbon content, carbon fiber uniquely combines the inherent strength of carbon materials with the workability of fibrous structures – establishing itself as a transformative high-performance material for modern industry.
China now enjoys its most promising era in carbon fiber R&D and production. Applications span military, advanced manufacturing, and consumer sectors – from spacecraft and launch vehicles to everyday items like eyewear frames, pen holders, and fishing rods. Though China's industrial development started later than Japan and other advanced nations, resulting in technical gaps, product quality continues rising. Within years, domestic carbon fiber is projected to achieve:
- 10GPa tensile strength
- 5% elongation at break
- Enhanced toughness with reduced brittleness
- Expanded application boundaries
Given its high-performance nature, carbon fiber undergoes rigorous testing. International standards follow GB 3362-3366-82 Test Methods for Carbon Fiber, while Japan employs JIS S7601-1982. For structural parameter analysis of carbon/graphite fibers, the industry predominantly adopts Japan's gakushin-ho (JSPS method) testing framework.
