Sensitivity Analysis of the Elastic Properties of Graphene/Fiber‐Reinforced Nanocomposites

Polymer Composites, EarlyView.
The formation of graphene/fiber‐reinforced nanocomposites. ABSTRACT This study offers a detailed sensitivity analysis of the elastic behavior of graphene/fiber‐reinforced nanocomposites using a multiscale micromechanical modeling framework. It focuses on key elastic properties, which are the longitudinal modulus (E11$$ {E}_{11} $$), transverse modulus (
