Machining Properties Of Carbon Fiber Composites


As a new generation of reinforcing material, carbon fiber has superior performance. Its weight is very light, its density is less than a quarter of that of steel, and its strength is four times that of steel. In addition, it has fatigue resistance, shock resistance, low thermal expansion coefficient, High temperature resistance, good dimensional stability and a series of advantages. Usually, carbon fiber materials are not used alone, but combined with resin to make composite materials. In this article, the editor will tell you about the machining characteristics of carbon fiber composite materials.
 
Machining properties of carbon fiber composites:
  • 1. The interlaminar strength is low. If the drilling axial force is too large and exceeds the strength that the resin can bear, defects such as delamination will occur;
  • 2. It is an anisotropic material, which has different performance indicators in different directions, and the laying direction of its fibers has a great influence on the hole making. If the stress is too concentrated, it is prone to breakage and other defects.
  • 3. Its hardness is high, so the tool is easy to wear during machining.
  • 4. Its thermal conductivity is small, the heat generated by friction during machining is difficult to remove, and it is easy to accelerate the wear of the drill bit, and there will be a lock hole phenomenon.
 
At present, the difficulty of machining carbon fiber composite materials is mainly concentrated in the drilling process, which requires strict process parameters and selection of suitable tools. Compared with traditional materials, although carbon fiber composite materials are difficult to process, their accuracy is not bad at all, and can be controlled between 0.05mm and 0.15mm to meet the requirements of use.
 
With the development of technology, carbon fiber production and machining technology has gradually matured and is very popular in the market. China Be-cu Prototype Material Technology Co., Ltd. has more than ten kinds of professional machining equipment, such as large-scale hot presses, hot presses, hydroforming tables, Cnc high-speed milling machines, etc., specializing in machining carbon fiber products. It is an early start-up company in the Yangtze River Delta region. A manufacturer of carbon fiber products in the automotive industry, , medical equipment, and rail transit.

Various capabilities include notching, labeling, drilling carbon fiber, grinding, laser cutting carbon fiber, finishing, plating, marking, CNC milling carbon fiber and turning carbon fiber.We stock high quality 3k carbon fiber sheet in a variety of thickness, types and finish. Its a great material used in applications where light weight and strength are needed such as drones. Unlike other workshops, we have no min order and are often filling orders with a single part. We also don’t make you pay for the full sheet and you only get charged for what is used. With a large selection of material, you should find everything you need to make your project come to life. We are also able to handle larger production runs and provide a competitive pricing. If we don’t have the material or finish you require, we are more the willing to look at bringing it in for you.

What Is Carbon Fiber?Carbon fiber is made of polyacrylonitrile (PAN) (or pitch, viscose) and other organic fibers by carbonization (removal of most elements except carbon) by pyrolysis method under inert gas at high temperature above 1,000 °C. Inorganic polymer fibers with a carbon content of more than 90%.
