The usage of synthetic nonwoven materials is gaining importance in filtration. However, the complex material behavior these synthetic, fiber-based challenging for manufacturing departments. are exhibiting a highly anisotropic elastic-plastic behavior. A testing program was conducted to characterize unknown characteristic filter media all three spatial directions load cases tension, compression, and shear first time. For conversion processes like cutting, embossing, calendering, pleating,...
Based on filtration simulations, virtual filter media development is used to design new nonwoven microstructures with increased performance. However, the processability in subsequent manufacturing processes of these designs not guaranteed. The ability predict mechanical properties crucial their processability. This paper introduces a microstructural simulation model based micro-computed tomography scans (µCT scans) three-dimensional elastic-plastic behavior polypropylene fibers. A analysis...
