This study aims to prepare bamboo-fiber-reinforced cement composites and provide a solution the issue of poor interfacial adhesion between bamboo fibers matrix. The original were modified by three moderately low-cost easy-to-handle treatments including glycerol, aluminate ester, silane treatments. performance was evaluated series mechanical durability tests, flexural compressive strength, water absorption, chloride ion penetration, drying shrinkage, freeze-thaw resistance, carbonization. In...

Plant fiber-reinforced composites have the advantages of environmental friendliness, sustainability, and high specific strength modulus. They are widely used as low-carbon emission materials in automobiles, construction, buildings. The prediction their mechanical performance is critical for material optimal design application. However, variation physical structure plant fibers, randomness meso-structures, multiple parameters limit composite properties. Based on tensile experiments bamboo...

Abstract The processing variables for making hemp‐fiber‐reinforced unsaturated polyester (UPE) composites were optimized through orthogonal experiments. It was found that the usage of initiator, methyl ethyl ketone peroxide, had most significant effect on tensile strength composites. treatment hemp fibers with a combination 1,6‐diisocyanatohexane (DIH) and 2‐hydroxyethyl acrylate (HEA) significantly increased strength, flexural modulus rupture, elasticity, water resistance resulting hemp‐UPE...

Abstract Functional diet and food safety requirements, as well reducing the consumption of nonrenewable resources environmental pollution are important development themes on processing. The application edible nanocelluloses (NCs) is an urgent need in current field. NCs divided into three types, including cellulose nanofibrils, nanocrystals from natural fibers, bacterial synthesized by bacteria. In this review, recent developments surface modification, biological properties, issues, their...

Hemp fiber-reinforced unsaturated polyester (UPE) composites were prepared by hand lay-up compression molding. The UPE resins modified with butyl methacrylate (BMA) to improve the flexibility and toughness of hemp-UPE composites. results indicate that significantly increased as BMA usage increased. Compared unmodified composites, obtained from BMA-modified had 27.4, 63.0, 36.6% greater elongation at break, flexural strain, impact strength, respectively. optimum achieve an adequate balance...

Bamboo fibers (BFs)‐reinforced unsaturated polyester (UPE) composites were prepared by hand lay‐up compression molding. The UPE resins modified with 2‐acetoacetoxyethyl methacrylate (AAEM) and designed to improve the flexibility toughness of BFs–UPE composites. results indicated that significantly increased as AAEM usage increased. When compared untreated composites, obtained from (with a 20:80 weight ratio UPE) had 21.7% higher impact strength. Dynamic mechanical analysis showed...

Composite paper sheet containing titanium dioxide and diatomite (TiDI) was prepared via a papermaking technique. The composite applied to remove phenol from aqueous solution. with 2:1 mass ratio of cellulosic-fiber TiDI removed more effectively under UV irradiation than the that utilized (TiO2) alone. sheets contained TiO2/diatomite 1:2 most effectively. results showed could serve as functional material photodegrade solution
