The objective of this study is to convert bamboo into a transparent material with great optical transmittance and good strength. Bamboo has much faster regeneration rate than wood, but its high density extractive content make it challenging produce products. This presents simple effective approach that could address challenge. Pretreatment low concentration sodium hydroxide greatly improved the preparation efficiency bamboo. thickness 1 mm cellulose volume fraction 22% made from pretreated...

Bamboo is a functionally graded material with natural hygroscopicity, and the study of response its cell structure to humidity will help expand use in textiles engineering structures. For this purpose, study, hygroscopicity moso bamboo (Phyllostachys edulis) gradient fiber was assessed by dynamic vapor sorption (DVS) apparatus fitted Haillwood–Horrobin (H–H) model. The effects chemical composition, structure, mesopore were also investigated. results demonstrate that gradually increases from...

Bamboo is a unidirectional fiber-reinforced material with excellent flexibility and flexural toughness arising from its unique cellular hierarchical structure, which creates an urgent demand in the bamboo industry to understand potential mechanisms of those two performances. In this study, proposed original method was used quantitatively evaluate gradient distribution aggregate structure fibers on natural moso (Phyllostachys edulis) bamboo, comparison other wood. Results showed that across...

The push for sustainability in all facets of manufacturing has led to an increased interest biomass as alternative non-renewable materials. Hemp bast fiber mats were produced from a bacterial retting process, named BFM, the reinforcement. objective this study was evaluate feasibility laminating BFM with polylactic acid (PLA) composite panel product. Since both and PLA are biodegradable, resulting BFM-PLA composites will be 100% biodegradable. pallets processed into thin polymer sheets which...

Abstract Uncrosslinked cis–trans polybutadiene films were prepared on ultraclean glass microscope slides by uniform dipping. The samples stored in different environments prior to evaluation of surface oxidation dynamic contact angle using the Wilhelmy plate method and X‐ray photoelectron spectroscopy (XPS). Storage conditions evaluated were: (1) laboratory air at 20°C 30% relative humidity; (2) vacuum 0.1 torr; (3) distilled water equilibrated with air; (4) degassed water. XPS analysis...

Carbon nanomaterials-based electric double-layer capacitors (EDLCs) are reliable and appealing energy-storage systems offering high power density long cycling stability. However, these energy storage devices plagued with critical shortcomings, such as low specific capacitance, inefficient physical/chemical activation process, self-discharge of electrode materials, hindering their future application. In this work, we use a self-activation an environmentally benign low-cost to produce...

The lack of an effective and practical quality control method for industrialized bamboo bundle veneers is the key restriction in application composite materials field construction. In this work, density uniformity mechanical properties were systematically evaluated by combination light transmittance stiffness. It was found that number broomings, dippings, high-temperature heat treatments had different effects on veneers. On basis, scrimber (BS) underwent hybrid paving, laminated veneer...

A new bio-composite pipe structure named bamboo winding composite (BWCP) was made of slivers, and its mechanical performance investigated. Bamboo that is lightweight has high strength properties can be used in water conveyance projects as a green alternative to traditional pipeline materials. Continuous lengths slivers were reinforced with resin matrix, which then fed through arch-shaped winder fabricate the BWCP. The specific ring stiffness BWCP comparable fiberglass plastic (GFRP). density...
