Abstract
Cellulose nanofibrils (CNFs) and the continuously assembled microfibers have shown transversely isotropic
behavior in many studies. Due to fact that the size of CNFs and the assembled microfibers is at the nano and
micro scale, respectively, the characterization of their mechanical properties is extremely challenge. That
greatly hinders the accurate multi-scale modeling and design of CNFs-based materials. In our study, we have
characterized the elastic constants of both CNFs microfibers and CNFs through a Multi-scale Optimization
Inversion technology. Through the tensile test of CNFs microfibers reinforced resin with different volume
fractions and the micromechanics model of microfibers reinforced resin, the elastic properties of CNFs
microfiber can be backed out via the Particle Swarm Optimization (PSO) method. Next, the mechanical
properties of CNFs at the nano scale are derived based on the previously obtained properties of CNFs
microfibers and micromechanics model of CNFs fibers via a second-time optimization-based inversion
process. These results provide a foundation for an accurate multi-scale modeling and design of CNFs-based
materials and structures.
