Carbon Fiber Reinforced PA66 Composites

PA66 CF composite material exhibits the following key performance metrics in robotics applications: density of 1.3-1.4 g/cm³ providing over 30% weight reduction compared to aluminium alloys and significantly reducing motion inertia; tensile strength of 150-220 MPa flexural strength of 180-260 MPa and flexural modulus of 12-20 GPa. MPa and flexural modulus of 12-20 GPa meeting the high rigidity requirements of robotic arms. Heat deflection temperature (1.82 MPa) reaches 240-255°C with a long-term service temperature of 120-155°C. The aluminium alloys are also suitable for use with the robotic arms. With a carbon fibre content of 20%-40% the material offers excellent dimensional stability (water absorption <1.51TP). With a carbon fibre content of 20%-40% the material offers excellent dimensional stability (water absorption <1.5%) and a low coefficient of thermal expansion (2-3×10-⁵/°C). In terms of electrical properties its surface resistance ranges from 10³ to 10⁵ Ω/sq providing electrostatic dissipation capability. friction coefficient is 0.15-0.25 and its wear resistance surpasses that of common engineering plastics. Its fatigue life can reach up to 10 Its fatigue life can reach up to 10 ⁷ load cycles making it particularly suitable for high-dynamic repetitive motion applications such as joint components.
