Ultra-Low Molding Shrinkage Molding shrinkage rate of only 0.1%-0.3% with thermal expansion coefficient of 1.8×10⁻⁵/°C ensures extremely high dimensional accuracy and stability for products made from PLA CF50 Pellets. 5. Outstanding Wear Resistance Taber wear test shows wear loss of only 18mg/1000cycles, approximately 75% improvement over standard PLA, significantly extending product service life.
III. Material Primary Applications
The PLA CF50 composite material is widely used in automotive structural components, aerospace models, industrial load-bearing frames, high-end sports equipment, and precision instrument housings. Its exceptional mechanical properties and unique environmental friendliness make it an ideal choice for manufacturing high-strength, lightweight engineering components.
IV. Application of PLA CF50 in Automotive Roll Cages
A racing car manufacturer utilized Carbon PLA Masterbatches through Extrusion Molding process to manufacture roll cage structural components for lightweight racing cars. The excellent processing performance of PLA CF50 Pellets ensured precise molding of complex curved structures, while its 125MPa tensile strength and 15.5GPa flexural modulus provided sufficient impact resistance for the roll cage. In actual crash tests, the roll cage withstood 15kN static pressure with deformation less than 2%, achieving 60% weight reduction compared to traditional steel structures and significantly improving the vehicle’s power-to-weight ratio and handling performance. The successful application of PLA CF50 in this safety-critical component demonstrates its exceptional performance in high-end structural applications.

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.
