Carbon fiber stands out as an exceptionally popular material today-combining metal-like strength with paper-like lightness, perfectly embodying "lightweight yet robust." Beyond this, it excels in heat resistance, chemical corrosion resistance, and low friction. As technology advances, carbon fiber performance continues to evolve, now categorized into standard grades and high-strength, high-modulus (HSHM) grades. But what exactly qualifies carbon fiber as HSHM?
While no universal definition exists, carbon fiber is generally considered HSHM when meeting either of these criteria:
Tensile strength exceeding 2 GPa and modulus over 50 GPa per unit cross-sectional area,
OR
Tensile strength above 120 g/D and modulus over 500 g/D per unit mass.
Researchers classify carbon fiber into T-series (strength-based) and MJ-series (modulus-based). Strength ranks as T1000 > T800 > T700 > T300, while modulus follows MJ60 > MJ40 > MJ35. Standard-grade carbon fiber suffices for everyday items like wallets, bottle holders, cups, or chairs. However, advanced applications-race cars, rockets, and aerospace components-demand HSHM carbon fiber to meet extreme performance requirements.
With this understanding, you can better identify true HSHM carbon fiber. As the carbon fiber market expands, High Gain Industrial Co., Ltd. stands ready to support your specialized needs.
