Intelligent solutions with modern materials

Carbon fiber reinforced plastics (CFRP) offer a huge application potential due to their outstanding lightweight construction properties. Especially the high specific strength and stiffness (relative to the density) compared to other materials such as stainless steel and aluminum have to be pointed out.

What used to be important in the past in aviation and racing sport plays an important role in almost all areas of industry today. This modern material is used, among other things, increasingly in automotive engineering, automation technology and sports.

Other properties:
• High chemical resistance
• X-ray transparency
• Non-magnetic
• Electrically conductive

Due to the various processing methods, different single components can be combined to one, which is not or only cost intensely possible in other material combinations. This allows each material to be used where its properties are most useful. That’s why hybrid lightweight construction becomes spreaded more and more.

An application example are target devices for trauma surgery, which enable an exact and secure fixation of bone fractures. The use of CFRP ensures an easy handling and the x-ray transparency allows control of the exact nail position during the operation. The clinical requirements for hot steam sterilization and biocompatibility are also met. Wherever, for example, high abrasion resistance, hardness or very tight tolerances are needed, stainless steel can be used.

A further application example can be found in the area of automation technology, where moving masses must be kept as small as possible. Work operations can be done more energy-efficient or higher masses can be moved. For cost reasons even here hybrid leightwight construction with stainless steel or aluminum can be carried out.

As matrix system for the fibers thermosets are available as well as thermoplastics. The application temperatures range from far below the freezing point for space applications up to 240°C for aviation or medical technology. For medical technology, our materials are tested and approved according to ISO 10993 and other standards. Products made from these materials can be steam-sterilized many times.

Wet pressing
During wet pressing so-called prepregs are inserted into a hot tool and cured under pressure and temperature. Instead of milling three-dimensional contours out of a thick plate, the components can be produced directly with the necessary outer contour.  That leads to minimal additional mechanical work and saves money. Beside that parts have higher stiffness and strength as the fibers can follow the load paths more efficiently.
