Wood-like or woody mimic biocomposite materials can be formulated from lignocellulose and hemicellulose matrices loaded with lignocellulose components. For example, xylan and plant-based oil matrix-based biocomposites can be prepared with diverse cellulose micro-and nano fillers and fibers. Those are prospective mutual biobased and biodegradable materials derived from renewable resources, while lignocellulose could be delivered from forest and plant biomass waste. We propose lignocellulose nanoparticles assembly strategy from solution and processed by hot press fabrication and resin infusion that can be used to process woody mimic biocomposites. Performance properties have been dependent on the chosen material composition, formulation process, lignocellulose modification route, and biocomposite fabrication. Rigid, soft, and ductile biocomposites’ mechanical behavior can be achieved. Thermal, tensile, viscoelastic, thermo-mechanical, dynamic-mechanical, rheological, and biodegradation properties of the wood-mimic composites are reported. The obtained biomaterials can be a sustainable alternative to replace fissile source polymers and conventional composites, e.g. wood polymer composite.
