Continuous load path-optimized textile technologies for lightweight structures in mass production
Motivation and problem
The use of classic FRP materials with thermosetting matrix in automotive mass production, despite its potential for lightweight construction, is lacking efficiency due to its cost- and time-consuming production. Reasons for that are mainly the energy-intensive production, the high costs due to waste and the relatively complex process technology (poor possibility of automation).
One approach to increase the economic efficiency is to make use of classic mass-production processes (e.g. forming) for the use of thermoplastic matrix systems as well as the adjusted manufacturing of the preform, aligned with the flow of force. Besides the development of manufacturing technologies for efficient production of load path-optimized textiles including their quality assurance, the use of thermoplastic matrices faces various challenges like the compatibility of carbon fiber and matrix or the effective impregnation and forming of textiles.
Project goals and contents
The goal of the joint project ”Continuous load path-optimized textile technologies for lightweight structures in mass production (KonText)“ is to provide a production technology that enables a production of load path-optimized, thermoplastic FRP in a cost-efficient way with high quality standards. As a metric value it is required to produce a component in fiber composite construction that is 25% lighter than the reference component and 30% cheaper than in classic CFRP (carbon-fiber-reinforced polymer) production.
