N2 - • X-ray micro (nano) computed tomography (X-CT) offers unique opportunities for visualization and characterization of 3D structures of bio-based materials and biocomposites. • Finite Element Analysis (FEA) using actual 3D images provide an advanced capability in (scale free) property estimation of porous materials and composites. • Biobased materials significant variability in the structure needs to be considered. • Heterogeneities in the structure result in variation in mechanical properties. • Despite the variability, unique non-linear relationship between solidity and normalized elastic modulus, similar to normalized transport properties. • Even though Halpin-Tsai may not be directly applicable to non-matrix filled, porous materials, the FEA results provide an equivalent L/D for the fibrous structures which are significantly greater than that of the initial fibers reaffirming the complex, highly interconnected, network structure. • With suitable resolution images, bio-based composites and nano-composites properties can be predicted using 3D images, FEA and constituent elemental properties.
