1. Excellent Mechanical Properties
PA6 CF50 offers a tensile strength of up to 285 MPa and an elastic modulus of 21 GPa, representing an approximately 300% improvement over unreinforced PA6, making it suitable for high-load structural components.
2. Outstanding Heat Resistance
Heat deflection temperature (1.82 MPa) reaches 218°C, allowing for long-term use in high-temperature environments while maintaining dimensional and performance stability.
3. Low Warpage and High Dimensional Accuracy
The molding shrinkage rate of PA6-CF-BCA5 is only 0.2%, significantly reducing part warpage and meeting the assembly requirements for precision components.
4. Superior Fatigue Resistance
Fatigue strength remains at 85% of its initial value after 10⁷ load cycles, outperforming most engineering plastics.
5. Good Chemical Stability
Exhibits good resistance to lubricants, fuels, and most solvents. PA6 CF50 is particularly suitable for components within automotive engine compartments.
III. Material Primary Applications
This material is widely used in automotive lightweight components (e.g., transmission brackets, battery housings), aerospace structural parts, industrial robot arm sections and precision guides, sports equipment, and high-end electronic enclosures. The PA6-CF-BCA5 grade, due to its optimized interface, is particularly suited for dynamic structural parts and dynamic structural components subjected to complex stresses.
IV. CF-R Thermoplastic Composites Application Case in Automotive Lightweighting
A European automotive manufacturer adopted PA6 CF50 to replace traditional aluminum alloy for the battery module bracket in a new energy vehicle model, achieving a 40% weight reduction. The component underwent 2000 vibration cycles under environmental conditions ranging from -40°C to 120°C without cracks or deformation, effectively ensuring the safety and range stability of the battery system. The material also passed an electrolyte corrosion resistance test, increasing its service life by 30%.

Please note that the properties of carbon fiber-reinforced thermoplastic composites can be significantly influenced by the matrix resin type, fiber content, and production process. We recommend conducting comparative tests with specific types of carbon fiber-reinforced plastics based on actual application scenarios to accurately evaluate material advantages. Products from different manufacturers may vary in their performance focus.
CFRTP VERSUS CFRP
1. CFRTP demonstrates significantly faster processing time (5 minutes) compared to CFRP (45 minutes), representing a 90% reduction in manufacturing duration. 2. In terms of recyclability, CFRTP outperforms CFRP by a large margin, scoring 9 on a 1-10 scale versus CFRP's score of 2. 3. CFRTP exhibits superior impact resistance (90 kJ/m²) compared to CFRP (65 kJ/m²), showing approximately 38% better performance in this category. 4. While CFRP has higher temperature resistance (220°C) than CFRTP (180°C), both materials maintain adequate thermal performance for most applications. 5. CFRTP offers greater design flexibility (rating of 90) compared to CFRP (rating of 60), providing more versatility in manufacturing and application scenarios.
CFRTP VS. METALS
1. CFRTP exhibits the lowest density (1.50 g/cm³) among all compared materials, significantly outperforming traditional metals like steel (7.85 g/cm³) and copper (8.96 g/cm³), and even surpassing aluminum (2.70 g/cm³) and aluminum alloy (2.80 g/cm³). 2. In terms of strength-to-weight ratio, CFRTP demonstrates superior performance at 120 kN·m/kg, more than doubling the ratio of aluminum alloy (68 kN·m/kg) and far exceeding steel (26 kN·m/kg) and copper (14 kN·m/kg). 3. While steel shows the highest stiffness (200 GPa), CFRTP (150 GPa) outperforms aluminum (70 GPa), aluminum alloy (72 GPa), and copper (110 GPa), offering a favorable balance of rigidity and lightweight properties. 4. CFRTP achieves the highest corrosion resistance rating (9 on a 1-10 scale), surpassing all other materials including aluminum alloy (8), aluminum (7), copper (6), and steel (3), making it ideal for corrosive environments.
