High-strength 3K carbon fiber multi-axial fabric for lightweight Composite Solution
Product Overview
Our High-Strength 3K Carbon Fiber Multiaxial Fabric features carbon fiber tows made up of 3,000 filaments, demonstrating its commitment to state-of-the-art performance in high-performance composites. Through multiaxial warp knitting technology, fiber layers oriented at 0°, ±45°, and 90° are precisely laminated, forming a buckling-free, high-stability 3D reinforced structure. This innovative design endows the material with tensile strength ≥3500MPa (7-9 times that of steel) while maintaining low density (≤1.8g/cm³), achieving the perfect balance between lightweight and high strength.
Core Advantages
1. Multiaxial Structure Design, Omnidirectional Performance Optimization
- The fiber arrangement is designed to prevent buckling, with smooth layering of fibers in multiple directions through warp knitting. This approach reduces stress points common in conventional fabrics, resulting in improved strength and durability when it comes to tension, shear, and impact forces.
- Our customizable layup solutions are designed to accommodate 2-6 layer composite structures, including chopped fiber and non-woven layers. The system allows for precise adjustment of fiber angles and the number of layers, making it suitable for a range of industries such as aerospace and automotive. This flexibility helps optimize material use and performance based on specific application needs.
2. A balanced combination of lightness and durability.
- 3K Carbon Fiber Properties: Filament diameter as small as 5-7μm, with a specific strength of 2000MPa/(g/cm³). At equivalent strength, it is 40% lighter than aluminum alloy and 70% lighter than steel.
- Autoclave Process Enhancement: Adopting high-temperature and high-pressure curing technology, resin permeability is increased by 30%, product porosity is <1%, and surface flatness reaches Class A standards, meeting high-end manufacturing precision requirements.
3. Resistance to Extreme Environments, Longevity Assurance
- Chemical Stability: Resistant to acid and alkali corrosion (stable performance in pH 2-12 environments) and superior to stainless steel in salt spray erosion resistance, suitable for harsh scenarios such as marine engineering and chemical equipment.
- Fatigue Resistance: After 10⁶ cycles of load testing, material strength attenuation is <5%, far exceeding that of traditional metal materials.
4. Ensuring smooth process compatibility and swift responses.
- Multi-Resin System Adaptability: Compatible with mainstream matrices such as epoxy resin and vinyl ester resin, supporting processes like vacuum infusion, prepreg molding, and filament winding, adapting to customers’ existing production lines.
