Abstract In this study, we developed a micromechanical model for exploring the longitudinal tensile behavior of unidirectional discontinuous flax fiber reinforced epoxy composites, emphasizing the significant roles of the aspect ratio of fibers and fiber-matrix interfacial properties. Representative volume elements (RVEs) are built using a novel approach which accounts for the randomness of the fiber distribution, discontinuity of the fibers, and the modeling of the interfaces as cohesive zone elements.
Finite element simulations of the RVEs under longitudinal tension were performed with proper periodic boundary conditions (PBCs). We investigated how fiber aspect ratio, interfacial properties and matrix… More >
