Carbon Fiber Rod Tube

Through design, the power-to-weight ratio of the robotic arm can be optimized. Choosing lightweight manufacturing materials is also an important way to achieve lightweight robotic arms. 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 robotic arm consumes less energy during operation and runs more lightly and quickly. Even if the energy consumption ratio is only reduced a little, or the production efficiency is improved a little, the effect brought about in long-term and batch work is huge.

The basic weight that the robot arm has to bear includes the weight of the arm itself plus the maximum weight of the grasped workpiece. The strength ratio and modulus ratio of carbon fiber composite materials are much higher than those of steel. The tensile strength is generally above 3500Mpa, which is 7-9 times that of steel. This high load-bearing performance provides technical support for the diversified development of robots.

By reducing its own weight and energy consumption, the working cycle is extended exponentially. The working performance is stable in harsh climates such as severe cold and high temperatures, and it can complete instructions accurately and quickly. This is also an important reason why carbon fiber composite materials are preferred in robot design in many specific working environments.

To give full play to the fatigue resistance of carbon fiber composite materials, we should start from the most basic design and production, because the actual fatigue resistance of carbon fiber composite robot arms is often subject to the angle design of the composite material ply direction and the load direction. Therefore, when using carbon fiber composite materials to make robot arms, it is necessary to design a special production plan for the load and actual working conditions borne by the robot arm.
