Key Performance Indicators of Carbon Fiber Composites: Analyzing the Physical Properties of High-performance Fibers

(1) Tensile Strength: Refers to the maximum stress a fiber can withstand when subjected to tensile force. Carbon fibers with high tensile strength provide better structural performance, such as in aerospace composites that require high strength.

(2) Modulus: Refers to the stiffness of the fiber, i.e., its ability to resist deformation when subjected to external forces. Carbon fibers with a high modulus have good stiffness, such as in composite materials for race car chassis manufacturing, which need high stiffness to withstand the stresses of high-speed driving.

(3) Elongation: Refers to the change in fiber length relative to its original length when subjected to tensile force. Carbon fibers with high elongation have better ductility and impact resistance, such as in sports equipment like golf club shafts, where higher elongation helps provide better shock absorption performance.

(4) Thermal Conductivity: Carbon fibers have high thermal conductivity and can efficiently conduct heat. For example, in heat sinks or electronic device cooling solutions, using carbon fiber composites can improve the device's heat dissipation efficiency.

(5) Electrical Conductivity: Carbon fibers have some electrical conductivity and can be used for certain specific conductive applications. For example, carbon fiber composites can be used to make anti-static products to prevent damage to electronic devices from static electricity.

(6) Corrosion Resistance: Carbon fibers have excellent corrosion resistance and are not easily affected by chemicals and environmental factors. For example, in chemical industries or marine environments, using carbon fiber composites can reduce equipment maintenance costs.

(7) Mass: The mass of carbon fibers determines their weight in composite materials. Lightweight carbon fibers have significant advantages in automotive, aerospace, and other fields, as they can help reduce weight and improve fuel efficiency.
