Fiber reinforcement or foaming allows the mechanical properties to be specifically adapted and structural lightweight applications to be implemented in vehicle and appliance construction. The target variables here are weight-related stiffness and strength: fiber reinforcements increase stiffness and strength for the same weight, while foamed materials allow a reduction in weight with comparable strength. While the design is often based on quasi-static characteristic values, highly dynamic loads occur in the event of a crash, which must be taken into account in the design process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The work is related to this research project:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The work is part of a current research project that is investigating the stiffness and strength behavior of fiber-reinforced and foamed thermoplastics under crash loading. At present, these effects are usually only taken into account in component dimensioning by means of rough safety factors. The aim of the project is therefore to systematically investigate how the deformation and failure behavior changes under increased loading speeds. In particular, the influence of the material configuration, such as fiber orientation and foam morphology, should be taken into account. Practical dimensioning methods for industrial applications are to be derived on this basis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Objective:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To begin with, you will learn the injection molding process and the specific variation of production parameters to produce different material configurations. On this basis, test geometries with varying fiber orientation and\/or foam morphology are produced, which form the basis for further investigations. You extract suitable test specimens from these and carry out dynamic impact tests on the drop tower. A high-speed camera is used to record and evaluate the local strain using video extensometry. You will learn the experimental investigation of material behavior under highly dynamic stress and the analysis of deformation processes in the millisecond range. Based on the experimental results, you finally derive a dimensioning method that takes into account both the influence of the process-dependent material morphology and the loading rate on the deformation and failure behavior.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Your task:<\/h3>\n\n\n<style type=\"text\/css\">#table-from-csv-block_d1ed78014e6c34f16ce76cb4e6f72935 table:not(thead)
