T700 chopped short carbon fiber

T700 chopped short carbon fiber-Carbon fiber chopped strands are obtained by cutting PAN carbon fiber precursor filaments into specific lengths using cutting machines. Due to carbon fiber's superior properties such as high strength, high modulus, low density, high electrical conductivity, low thermal expansion coefficient, low friction coefficient, acid and alkali resistance, and good stability under most environmental conditions and chemical reagents, it has been used as a reinforcing material for various thermosetting and thermoplastic resins. Adding a certain amount of carbon fiber chopped strands to resins can significantly improve various properties of products, such as enhancing the strength and modulus, increasing the hardness, improving dimensional stability and crack resistance, and boosting wear resistance of the products.

I. Core Characteristics and Reinforcement Logic of Carbon Fiber Chopped Strands

Adaptability of Raw Material and Morphology

Key Mechanisms for Performance Improvement

• Mechanical reinforcement: When the addition amount is 10%-40%, the chopped strands form a "skeletal structure" in the resin matrix. During stress, they transfer loads through the interface bonding between fibers and the matrix, significantly improving the tensile strength, flexural strength, and rigidity of the products, and reducing deformation.
• Functional optimization: Utilizing their low thermal conductivity and low expansion coefficient to improve the dimensional stability of products; their chemical corrosion resistance and low friction coefficient to enhance the service life of products.

II. Targeted Advantages in Application Scenarios

Thermosetting resin field

• Industrial molds (such as fiberglass molds): Improve the wear resistance and impact resistance of molds, and extend their service life;
• Wind turbine blades, high-pressure pipelines: Utilize their lightweight and fatigue resistance to reduce operating energy consumption.

Thermoplastic field

• Auto parts (such as engine brackets, gearbox housings): While reducing weight by more than 30%, meet the mechanical stability under high temperatures (engine compartment environment);
• Structural parts of electronic equipment (such as 5G base station housings): Use their low expansion coefficient to ensure the dimensional accuracy of precision components, and also have certain electromagnetic shielding properties (carbon fiber is conductive).

Special functional products

• Wear-resistant components (such as water pump impellers, seal rings): Low friction coefficient + high strength to reduce wear;
