Wood is a green, environmentally sustainable, high-performance structural material that an attractive candidate to replace nonenvironmental materials. However, the mechanical performance of natural wood generally insufficient in many advanced engineering structures and applications. Herein, we report simple effective strategy new type green-enhanced development synthesize high biomass structure from renewable resources. In this process, lignin partially removed, hard cell walls become...
Abstract To improve the toughness of polylactic acid (PLA), in this research, a tough polymer polycaprolactone (PCL) was combined with PLA to prepare blends, and compatibilizer glycidyl methacrylate grafted (PLA‐g‐GMA) produced enhance compatibility PLA/PCL blend. Compared blend, compatibilized blend exhibited lower melting temperature greater thermal stability. The tensile test indicates that addition greatly improved Particularly, elongation at break 6 wt% PLA‐g‐GMA increased 370% reached...
Abstract Fiber‐reinforced composites with a bionic Bouligand structure are known for their excellent mechanical properties. Currently, most of the research in this field focuses on man‐made fibers, and natural unidirectional fiber materials is still limited. This paper designing Bouligand‐inspired reinforcement creating wood fiber‐reinforced composites. We investigate effects helix angle bending properties, impact resistance extreme environments material through combination experimental...
Nano-cellulose aerogels have low densities, high porosities, and strong absorption capacities, making them suitable for cleaning up oil chemical spills in oceans. However, their weak lipophilicity poor mechanical properties often limit applications. We attempted to introduce long-chain polymers on the nanocellulose/polyvinyl alcohol (CNF/PVA) surface hydrophobic modification of aerogels. In this paper, PVA/CNF was silylated by introducing hydrolyzed ethyltrimethoxysilane increase its...
A hydrophilic wood surface was transformed to become superhydrophobic by layer-by-layer (LbL) assembly of polyelectrolyte/titanium dioxide (TiO2) nanoparticles multilayers and subsequent hydrophobic modification with 1H, 2H, 2H-perfluoroalkyltriethoxysilane (POTS). The chemical composition the samples before after treatment characterized energy dispersive X-ray analysis (EDXA), Fourier transform infrared spectroscopy (FTIR), diffraction (XRD), thermogravimetric (TGA). These analyses showed...
This paper designed and manufactured photosensitive resin-based 2-D lattice structures with different types of variable cross-section cores by stereolithography 3D printing technology (SLA 3DP). An analytical model was employed to predict the structural compressive response failure types. A theoretical calculation performed obtain most efficient material utilization core. flatwise experiment verify conclusions. comparison experimental results showed good agreement for response. Results from...
Abstract In this study, polylactic acid (PLA)/polycaprolactone (PCL)/microcrystalline cellulose (MCC) composites and PLA/PCL/MCC composite compatibilized by the maleic anhydride (MA) copolymer were prepared via two‐screw extrusion technology. The mechanical results showed that strength break elongation of ternary are decreased with increase in MCC contents. After grafting was added, due to better compatibility between components composite, significantly improved compared ungrafted composite....
Abstract This study proposes a novel biomimetic hierarchical square honeycomb structure made from reinforced wood, aiming to address the limitations of traditional structures, such as poor energy absorption after load failure and unstable deformation modes. Inspired by natural materials, design incorporates hollow circular substructures replace solid ribs, optimizing both mechanical performance absorption. Experimental finite element simulations were conducted investigate effects...

An orthogonal test was designed to evaluate influence distance, diameter, length on their compression energy absorption properties. Theoretical analysis finite element method conducted predict properties structures. The optimum specification...
In an effort to optimize axially compressed members of a wooden structure, composite 2-D lattice structures were designed and manufactured with wood-plastic composites as the panel glass fiber reinforced plastic core by using simple insert-glue method. The compressive behavior made cores different diameters inclination angles was investigated. Analytical models employed predict theoretical load capacity, equivalent strength, failure types structures. Reinforcing hoops then at two ends...
