Novel Design Methods for Composite Structures under High-Strain-Rate Loading Conditions

Fiber- and textile-reinforced composite materials are predestined for the application in high-performance lightweight constructions due to the extreme mechanical and technical requirements. In this respect, the design and dimensioning of structural components accounting for the configuration of the reinforcement, the rate dependency of the composite constituents, the direction of loading and the high-velocity loading conditions is still challenging. For this, an in-depth understanding of relevant material specific phenomena as well as according modeling approaches is required. Here, a methodology for glass-polypropylene (GF/PP) hybrid yarn-based composites is presented, which supports an adequate design process of composite structures under high rate loading.
