Strain sensing efficiency of hierarchical nano-engineered smart twill-weave composites: Evaluations using multiscale numerical simulations

This paper evaluates the strain-sensing ability of a nanoengineered hierarchical twill weave composite using multiscale numerical simulations. Piezoresistivity is incorporated in such by introducing carbon nanotubes (CNT) polystyrene (PSS) matrix so as to form percolating microstructure. The glass fiber weave, which itself contains CNT-modified PSS inside yarns, coated with thin film piezoresistive obtain smart configuration. methodology, presented this paper, captures intricacies at multiple length scales and implements various mechanical damage mechanisms subsequent interactive well consequent electrical responses yield macroscopic electromechanical response. simulated show excellent correlation experimental observations signifying efficacy simulation methodology. Such detailed approach can provide valuable insights towards tuning structural hierarchies for efficient design woven laminated composites.
