Carbon fiber composite material processing methods
The pursuit of high performance in various industries has led to the increasing application of carbon fiber. In practical applications, carbon fiber is often combined with resin and other matrix materials to form carbon fiber composite materials.
Cutting Process: The main reason why carbon fiber is difficult to cut lies in its high hardness and low interlayer shear strength, which leads to tool wear and burnout due to excessive cutting temperatures. To avoid these cutting difficulties, grinding or special processing methods are often used. However, grinding processes generally have low production efficiency, so the application of special processing methods (such as high-temperature cutting and vibration cutting) is more widespread.
Drilling Process: Drilling carbon fiber composite materials can easily lead to interlayer delamination, as well as phenomena like fraying and splitting at the exit edge. The causes of these problems stem from both the tools and the production processes. By controlling the tool's rake and clearance angles to ensure sharpness and utilizing lower feed rates and moderate spindle speeds, delamination defects can be avoided. Spiral milling for drilling can effectively reduce working temperatures.
Turning Process: The turning process is mainly aimed at achieving predetermined tolerances on cylindrical surfaces. The tools suitable for turning are mostly hard alloys and polycrystalline diamonds. In the machining process, the feed rate, depth of cut, and cutting speed all affect the quality of the finished workpiece.
