The significance of carbon fiber composite pipes for robotic arms

Carbon fiber composite pipe is currently one of the most widely used and abundant carbon fiber basic products, and it is also an important application form of carbon fiber composite materials. Carbon Fiber Tube has become a favored lightweight material in many fields due to their lightweight and strong performance advantages.

The work of industrial robots, medical robots, logistics loading robots, etc. is mainly completed by robotic arms, and the robotic arm is one of the main components for robots to perform operational tasks. The performance of a robotic arm determines its application value.Carbon fiber composite materials (CFRP) are lightweight, strong, and have good corrosion resistance, especially in environments with large temperature differences. The creep of the material is small, and its application in robotic arms can help improve the operational accuracy and efficiency of robots, and extend the service life of robotic arms.

CFRP robotic arm components

Nowadays, more and more new types of robotic arms are adopting carbon fiber composite materials. The weight of the robotic arm should be as light as possible, and the lighter the robotic arm, the smaller its moment of inertia. Choosing lightweight materials is also an important way for robotic arms to achieve lightweighting. The density of carbon fiber composite materials is only one-third of that of steel, and it is about 30% lighter than aluminum alloy, which means that the energy consumption during the operation of the robotic arm is less, making it more lightweight and efficient.

Industrial machinery CFRP robotic arm

The robotic arm needs to ensure sufficient load capacity while achieving light weight. The basic weight that a robotic arm needs to bear includes the weight of the arm itself plus the maximum weight it can grasp the workpiece. Carbon fiber composite materials have higher specific strength and specific modulus than steel, and their tensile strength is generally above 3500Mpa, which is 7-9 times that of steel. This high load-bearing performance gives robots the possibility to develop towards diversified functions.
