Material hybrid and sensor integrated lightweight machine tool components

Lightweight machine tool components provide the potential of improved system dynamics and reduced energy consumption. In this research, pre-stressed fiber-reinforced polymer concrete (PFRPC) structures were investigated, focusing on lightweight design and functional integration. An integrated strain measurement functionality was realized by embedding Fiber Bragg Gratings (FBG). Two versions of machine tool cantilever arms in the form of a Stewart platform were built using remaining plastic molds. The mechanical properties and operational characteristics were analyzed and compared with those of a conventional steel structure showing the high potential of the hybrid material with regard to the improved system dynamics.
