How Can Carbon Fiber be Processed Fast and Well?

Currently, the carbon fiber composite materials on the market are basically composed of carbon fibers and resin matrix, there is a relatively complex relationship between them. And the phenomenon of carbon fiber drawing or de-filamentation often occurs during processing. Due to the high hardness and anisotropy of carbon fiber composites, the requirements for processing equipment are relatively high, so a new processing method needs to be sought.

In response to market demand, Mitsubishi Electric has launched two new “CV series” CO2 3D laser processing machines by using the laser processing technology and development experience accumulated over many years, which are specially used for processing light-weight, high-strength carbon fiber reinforcement used in automobiles and so on. Composite materials (referred to as CFRP). The realization of high-speed and high-precision processing of CFRP products will contribute to the mass production of CFRP products that are difficult to achieve by traditional processing methods.

 

Products Features

Equipped with a three-axis orthogonal carbon dioxide laser oscillator of the Integrated-MOPA method, the oscillator and the amplifier are integrated into the same frame, and the laser light suitable for CFRP processing is emitted through a simple structure, which solves the problems of high-quality precision machining for CFRP that has been difficult to achieve so far.

The melting temperature of carbon fiber and resin is different, cutting CFRP requires a laser processing machine with steep pulse waveform and high power output, and the CV series products can meet these two requirements at the same time, achieving a faster level of processing speed, the speed is about 6 times faster than existing processing methods such as machining and water jet machining, contributing to increased productivity.

The equipped processing head can perform high-speed unidirectional (single-path) processing, so the production efficiency is higher than the laser processing method that irradiates on the same path multiple times.

The side gas nozzle mounted on the processing head can effectively remove the high-temperature material vapor generated during processing, suppress the thermal influence on the material, and realize the precise processing of three-dimensional shapes.

Compared with existing processing methods, non-contact laser processing can reduce the consumption of tools, etc., and the generation of waste contributes to reducing operating costs and help the realization of a sustainable society.

The control device is equipped with a dedicated CAM for path editing, and the processing path can be corrected on the processing machine, which improves the work efficiency.

A protective cover is standard around the processing machine to reduce the impact of dust on the working environment.

Conclusion

CFRP can meet safety requirements. The industry application side hopes to reduce material costs, increase processing speed, and achieve mass production. However, CFRP material manufacturers hope to use it in multiple industries, increase the amount of use, reduce prices, improve processing efficiency and pass product quality.
