Abstract In this experiment Artocarpus hirsutus (AH) fiber was utilized as the filler material for bamboo (NF)/polyethylene (PE) biocomposites. This a waste to wealth approach by utilising biomaterial and also can reduce use of PE plastics. The crystallinity index (Crl) 45.1%, 56.4%, 67% observed in AH, alkali treated (NaOH) cellulose AH respectively. combination with 20 wt% NF/3 better tensile flexural strength. Agglomeration at 4, 5 affects properties lesser interfacial adhesion filler/matrix phase, having reducing up 20.3 MPa. Comparing filler, both untreated combinations possess addition natural fibers increases modulus property 30 NF/5 combination. Impact strength doesn’t observe high influence incorporation. hasn’t been explored detail mechanical hydrophilic incorporation matrix. fabricated composite is suited bioengineering applications.

Published: Feb. 22, 2025

Abstract To explore the effect of bamboo winding angle on axial compression properties and failure modes thin‐walled tubes (BWTT), an test was conducted in this study. Seven distinct angles were considered. The micro‐morphology parenchyma cells, fibers, epoxy resin observed based scanning electron microscope (SEM) computed tomography (CT). micro mechanism BWTT revealed. results show that has a significant impact performance BWTT. With increase angle, load‐bearing capacity declines, whereas its ductility improves. Additionally, six strength criteria adopted to evaluate compressive BWTT, among which Hankinson criterion ( n = 2.33) demonstrated favorable applicability. continuous method (CSM) also predict good correspondence between predicted results. An stress–strain model proposed, Ramberg – Osgood (RO) considered influence parameters m θ . agree well with can provide theoretical foundation for application Highlights Winding analyzed by SEM CT. CSM Considering is proposed.

Abstract Based on the micro‐structure of wollastonite (WS) and bamboo flour (BF), a series PP/WS/BF ternary composite materials are prepared using blending, twin‐screw melt extrusion, injection molding processes. The experiment shows that formulation processing technology play significant impact structure, thermal, mechanical properties composites. BF has nucleation crystallization PP, while WS almost no effect PP. improves tensile strength enhances composites; bending flexural modulus rigidity Taking W‐B‐30‐1:3 sample as an example, its performance is highest at 23.33 MPa, well 26.23 904.67 respectively. combination leads to increase in storage modulus, decrease loss factor, glass transition temperature, bonding factor materials. This work can enrich scope PP materials, expected have potential applications fields automotive interior parts with lightweight. Highlights Heterogeneous among fillers Wollastonite more conducive improving thermal stability Adding effectively enhance properties. use increases interfacial compatibility performance.
