The effect of the packing density on the indentation hardness of cohesive-frictional porous materials
Natural composites in general and sedimentary rocks in particular are highly heterogeneous materials which defy a straightforward implementation of the materials science paradigm of microstructure-properties-performance correlation. The application of nanoindentation to natural composites has …

Incorporation of Bio Based Flax Fiber Reinforced Polymer Skins for Packaging Enhancements
This thesis provides an approach to incorporate natural composites like Flax Fiber using a resin with 30% bio-content to enhance the packaging boxes made of corrugated cardboard. The objective of introducing natural composite skins is to reduce/eliminate the compressive loading subjected to the …

Material invariant properties of shales : nanoindentation and microporoelastic analysis
… materials are probably one of the most complex natural composites, and their mechanical properties are still an enigma that has deceived many decoding attempts from experimental and theoretical sides. Advanced experimental techniques, such as nanoindentation, and theoretical microporomechanics …

Invariant mechanical properties of calcium-silicate-hydrates (C-H-S) in cement-based materials : instrumented nanoindentation and microporomechanical modeling
… pores of nm- to m-scale diameter. The natural synthesis and operating environments of such materials significantly alters phase composition and multiscale structural heterogeneities throughout the material lifetime, defining significant changes in macroscopic mechanical performance for …

Bio-inspired Cellulose Nanocomposites
Natural composites like wood are scale-integrated structures that range from molecular to the macroscopic scale. Inspired by this design, layer-by-layer (LbL) deposition technique was used to create lignocellulosic composites from isolated wood polymers namely cellulose and lignin, with a lamellar …
