Kurzfassung

An Andalusian research group has developed a new method for cutting carbon fibre composites. The best advantages are its industrial universal use, its low cost and generation of wastes. They are looking for license agreement or technical co-operation.

Details

An Andalusian research group has developed a new method for cutting carbon fibre composites.
Nowadays, with the development of composite and hybrid materials, has come the need for alternative methods in dealing with them for industrial applications. One such area, for example, is in the cutting methods such materials require. Lasers are often employed by manufacturers of composite materials to cut these materials into certain shapes and/or sizes. Lasers however, often do not meet absolute specifications in that hybrid materials' surfaces react differently than standard materials to the application of heat.
Carbon-fibre composites for example, are notorious in their ability to dissipate heat. As such, when cutting with standard industrial lasers, the cutting arc or area can be wider than required, resulting in large proportions of wastage both of material and energy used. Currently, composites materials are widely used for a big range of applications, from structural or recreational industry and it makes necessary the use of a machine which can treat the composites materials and obtain a desirable product by the industry.
It is a new composites laser machining method which main feature is the short heat affected zone promoted into the material (less than 150 micron) that makes it to have an industrial universal use because this novel method allows its application to a wide variety of industries.
On the one hand, this method achieves an excellent result of the process because uses an appropriate laser source in addition to the optimal operation parameters for laser.
On the other hand, it is a ecological method because it reduces the generation of waste and improves the occupational safety and health

Innovative Aspects:
This novel development has created a method whereby the heat-affected zone remains less than 150 microns proving the method with a variety of advantages, making it applicable to a wider range of industrial uses.
Aside from this benefit, the technology also offers additional advantages in that it reduces the production of waste and improves occupational health and safety standards.
Since the laser is more specific, it reduces operational costs, and can be easily introduced to other industrial concerns as it uses the same numerical controls as traditional machining.
