In this article, we will introduce why carbon fiber laser cutting is so important. And hope you can learn something useful from it.

Introduction of Carbon Fiber

In theory, carbon fiber is woven from inorganic fiber and then bonded together by the polymer matrix material. This material contains more than 90% carbon element and shows high strength, high-temperature resistance and corrosion resistance ability. The carbon fiber material is an important member of lightweight materials and is gradually replacing traditional metal materials in many industries.

Carbon fiber has wide applications in many manufacturing industries such as aerospace, wind power generation, automobile and so on. It is an ideal material to make precision parts for airplanes, satellites, cars and medical equipment. Also, carbon fiber composite materials are very popular for occasions that have higher requirements for weight and mechanical properties. Some examples are aviation components, boats, wind turbine blades, sports goods, medical equipment, automobile parts, etc. Carbon fiber is not metal, while its properties are better than metal and the price is much lower. Many professionals predict that carbon fiber will play a more important role in the near future.

How to Cut Carbon Fiber?

Before using carbon fiber material to make any products, we need to cut it into a suitable size or engrave it per different requirements. There are mainly two methods to process carbon fiber: Mechanical processing and special processing.

Traditional mechanical processing is to use mechanical knives to cut carbon fiber directly. However, this method has many problems in the machining process, such as the high cutting temperature of tools, severe material wear, high maintenance cost, etc.

The special processing methods include laser cutting, ultrasonic vibration cutting and electric spark cutting which are playing an increasing role on various occasions. These processing methods have wide applications in a variety of industries. Among these special processing methods, carbon fiber laser cutting is the most widely used cutting method. The laser cutting machine cuts carbon fiber by generating a high-power laser beam and melting and vaporizing the materials. Laser cutting has the characteristics of non-contact cutting, fast cutting speed, high cutting precision and automatic operation. Laser cut carbon fiber sheet has a smooth cutting edge. Carbon fiber laser cutting is a high-end carbon fiber cutting solution.

What is Carbon Fiber Laser Cutting?

Carbon fiber laser cutting uses a CO2 laser cutting machine to cut carbon fiber. The principle of CO2 laser cutting is: laser generator generates a laser beam and the laser beam irradiates on the carbon fiber. And then the part of carbon fiber melts and vaporizes instantly and forms a narrow slit.

Laser cutting carbon fiber has many obvious advantages over traditional mechanical cutting:

Firstly, the laser cutter adopts an intelligent cutting control system. And the control system can optimize typesetting automatically and reduces material waste.

Secondly, laser cut carbon fiber sheet has a smooth cutting edge and there is little to no burr.

Thirdly, laser cutting has no wear and tear to the cutting head and material. And this greatly reduces the processing cost and improves the quality of products.

Moreover, laser cutting shows high cutting precision and little error. And it can meet the strict processing standard of precision parts.

Last but not least, laser cutting runs automatically. It’s easy to learn and operate for beginners. And it brings users a good processing experience.

Application Prospects of Carbon Fiber Laser Cutting

Advantages of CO2 Laser Cutting Machine

As carbon fiber is a kind of non-metallic material, a CO2 laser cutting machine is suitable to cut it and produce a good cutting effect. CO2 laser cutting machine has the following advantages in carbon fiber processing.

  1. Non-contact cutting

CO2 laser cutter replaces the cutting knife with a laser beam. The laser head has no contact with the material, so there is no wear or tear.

  1. Automatic processing

A CO2 laser cutter is controlled by software. It shows the characteristics of accurate positioning, high processing precision and automatic typesetting.

  1. High precision

CO2 laser cutter has high cutting accuracy, almost no burrs and no need for subsequent processing. This greatly reduces processing costs.

  1. Strong cutting power

CO2 laser cutting machine delivers high-density laser beam which can melt thick materials. The higher the laser power, the thicker the cutting depth. For instance, a 100W CO2 laser cutting machine can cut 5-20 mm non-metallic materials.

  1. Wide applications

CO2 laser cutting machine can process various non-metallic materials including carbon fiber, acrylic, paper, wood, leather, fabric, glass, crystal, etc. It can help many enterprises and individuals expand the business, save processing costs and labor costs and get more profits.

  1. Unlimited processing patterns

The movement of the laser cutting head is controlled by a computer, so there are no limits to the patterns. CO2 laser cutter can process both simple and complex patterns on the work pieces.

Factors Affecting Carbon Fiber Laser Cutting Effects

Frankly speaking, a laser cutting machine is not a perfect machine. Some professionals have studied that laser cutting may cause a certain degree of thermal damage to the carbon fiber. Therefore, users need to pay attention to the following points and adjust proper parameters to reduce the thermal impact:

  1. Laser focus position

During laser cutting, the laser beam will be focused on a small spot to melt the cutting seam. The smaller the laser spot diameter, the smaller the heat-affected zone.

  1. Laser cutting speed

Generally speaking, faster laser cutting speed leads to a smaller heat-affected zone and better cutting quality. Therefore, it is necessary to adjust appropriate laser cutting speed to reduce the thermal influence and ensure the cutting quality.

  1. Laser cutting power

When the laser cutting power increases, the carbon fiber cutting efficiency is faster and the cutting quality is good. But the laser cutting power can not be too large. Excessive power will increase the heat-affected zone and the cutting slit. Users need to adjust the appropriate laser power for better cutting quality.

  1. Gas pressure

The gas pressure affects laser cutting quality to a certain extent. During laser cutting, the high-speed airflow quickly blows out the molten material and forms a cutting slit. However, if the gas pressure is too high, the blow-off capability will decrease. If the gas pressure is too small, it will cause an uneven cutting slit. Therefore, the gas pressure must be moderate to achieve a good cutting quality.

In conclusion, users need to pay attention to the above factors to reduce the thermal impact on the carbon fiber material. We suggest you conduct multiple tests, adjust laser power, cutting speed and other parameters to find the most suitable setting.
