Essen-based synthetic substances organization Evonik has built up an inventive assembling method for auto undercarriage parts.


The utilization of metal and plastic half and halves makes these parts 20% lighter than their metal partners.


The system was created as a component of the Multiform venture , supported by the German Federal Ministry of Education and Research (BMBF). In the task, Weber Fibertech and the University of Siegen were included close by Evonik.


Weber Fibertech provided a long fiber-fortified thermoplastic (LFT), which was expelled into a moldable semi-completed item.


In a liquid express, the material was then reinforced with a preheated metal sheet and, in a consequent creation step, squeezed into shape and at the same time joined.


The outcome is a composite cross breed segment that can be expelled specifically from the instrument for quick utilize.


Holding with the LFT empowers the utilization of a metal sheet that is a decent 1 mm more slender than regular. This diminishes the heaviness of the wishbones and trailing arms designed for the assembling of autos by around 20%.
