Core features (characteristics): All-round performance from physics to chemistry
The characteristics of carbon fiber are determined by its highly ordered graphite crystal structure, which is specifically manifested as follows:
1. Mechanical properties
Tensile strength: 2~7GPa (5~10 times that of steel);
Tensile modulus: 70~900GPa (3~4 times that of steel);
Elongation at break: 0.5%~2.5% (less brittle than glass fiber);
Fatigue resistance: extremely long life under cyclic load (carbon fiber for aircraft engine blades can withstand more than 100,000 takeoffs and landings).
2. Physical properties
Density: 1.5~2.0g/cm³ (only 1/4~1/3 of steel);
Thermal conductivity: 10~150W/(m·K) (high thermal conductivity along the fiber axis, low thermal conductivity perpendicular to the axis, customizable heat dissipation materials);
Thermal expansion coefficient: -0.5~+1×10⁻⁶/℃ (negative expansion coefficient direction can be used for precision compensation structure).
3. Chemical properties
Corrosion resistance: resistant to strong acids (such as concentrated sulfuric acid) and strong alkalis (such as sodium hydroxide), but not resistant to strong oxidants (such as molten caustic soda);
Weather resistance: UV resistance (surface treatment required), aging resistance (10 years of outdoor use strength retention rate> 80%).
4. Processing performance
Compositeness: Combined with resin (epoxy, phenolic), metal (aluminum, titanium), and ceramic matrix to form high-performance composite materials;
Flexible molding: Supports multiple processes such as molding, winding, pultrusion, 3D printing, etc. (adaptable to complex shapes).

These Classic styles are woven for their fiber orientation and are the most commonly used in the composites industry. They include plain and twill weaves, available in a variety of densities and thicknesses. Plain weave styles are less pliable but hold together well when cut. On the other hand, twill weaves feature fibers that run straighter for greater lengths--maintaining the theoretical strengths of the fiber--so they are more pliable and stronger than plain styles.
Carbon fiber is a strong, lightweight, and stiff material that is made from thin, strong crystalline filaments of carbon. It is made by heating and stretching strands of carbon until they become long, thin fibers, which are then woven or braided together to form a fabric. Carbon fiber materials are known for their high strength and low weight, and they are often used in a variety of applications where these properties are important, such as in the aerospace, marine, and automotive industries, as well as in sporting goods and other consumer products.
Carbon fiber can be used in many forms, including woven fabrics, braids, and unidirectional sheets. They are commonly combined with resins or metals to create composite materials that have even more desirable properties. Carbon fiber products are often used as a substitute for steel or other traditional materials to reduce weight and improve the performance of a structure or product.
Due to their unique properties, carbonfiber sheet and plates are used in numerous applications over traditional materials like aluminum, steel and titanium.
