“…This reduces fiber diameter resulting to an increase in aspect ratio. 16 Alkali treatment also increases fiber roughness. On the other hand, plasma treatment using atmospheric glow discharge (AGD) with plasma source using high voltage radio frequency (RF) was used to effect both fiber roughness and polymerization on the fiber surface (by introducing the appropriate monomer into the chamber).…”

“…7 Several researchers have attempted to improve the interfacial bonding between the natural fibers and the matrix by altering the hydrophilic nature of the fibers. Several methods to achieve this include chemical treatment, [8][9][10][11][12][13][14] acetylation of the hydroxyl group of the fibers, 15 post-treating with urotropine and urea 16 and the well-known process of alkali treatment. 10,[14][15][16] Alkali treatment has the potential of improving fiber strength by removing lignin, hemicellulose, and pectin.…”

To improve the adhesion and wetting between the abaca fibers and matrix, the surface of abaca fabric was modified using plasma polymerization. Different plasma exposure times were conducted to determine the effect of plasma treatment on the properties of the composites. A combination of plasma and other surface modification processes was also investigated to determine whether double treatments could further enhance the properties of these composites. Combined treatments involve plasma polymerization of the fabric after pretreatment with one of the following surface-modification reagents: a) γ -methacrylopropyltrimethylsilane, b) triethoxyvinylsilane, and c) 2% w/w NaOH (aq).The abaca fabric/unsaturated polyester composites were fabricated using the vacuumassisted resin transfer molding (VARTM) technique.SEM results showed that 10 to 20 seconds plasma treatment gave the right amount of surface roughness for maximum fiber and matrix adhesion leading to improved mechanical properties of the composites. Longer plasma treatment time and double treatment however resulted in composites with lower mechanical properties. Although the composite with alkali and plasma-treated fabric showed the lowest mechanical properties it exhibited the lowest water uptake in both distilled water and brine solution.

“…Glass fiber that is difficult to be decomposed triggers serious health and environment problems. They cannot be recycled easily by heat because they melt in very high temperature and still produce residues that may spoil the environment and are relatively abrasive in nature, as what are mentioned in the result of some studies [1][2][3][4][5]. The main focus of this study is to find out the potency of natural fiber of stinging nettle as the replacement of glass fibers as reinforced composite fibers.…”

Abstract. Stinging Nettle (Urtica dioica L., latin) is a wild plant that grows in Indonesia, Asia, and Europe. Nettle in Bali, Indonesia is called as Lateng, Jelatang. Nettle plant has a very strong fiber and high fixed carbon. Nettle plants are covered with fine hairs, especially in the leaves and stems. When it is touched, it will release chemicals, sting and trigger inflammation that causes redness, itching, bumps and irritation to the skin. Nettle plants grow in the wild, regarded as a weed in the agricultural industry, easy to grow and snatch food from the parent plant. The main objective of this paper is to review of the potential nettle fibers and then explain about the potential of local nettle plant in Indonesia. Nettle is a plant group at the end of bast. Its plant fibers taken from the bark, as reinforcement in composite materials. Nettle fibers have three main advantages such as strong, lightweight and low environmental impact.

“…More than 90% of all ramie plants are grown in China. Ramie is world-famous for its excellent fiber properties, such as high tensile strength, excellent thermal conductivity, coolness, ventilation, moisture absorption and antibacterial properties, and the best ramie fibers are used for textiles [20]. In addition, many studies have demonstrated that ramie could be used as an ingredient in forage proteins due to its equal nutritional value with alfalfa (Medicago sativa), high protein and amino acid levels, reasonable nutrition composition and high biomass [21,22].…”

Glutamine synthetase (GS) plays a fundamental role in nitrogen metabolism in higher plants. Three BnGS genes have first been isolated: one gene encoding plastid GS (BnGS2) and two encoding cytosolic GS (BnGS1-1 and BnGS1-2) in ramie. Based on a sequence analysis and phylogenetic study, three BnGS sequences were classified into three distinct sub-families. The phylogenetic analysis showed that BnGS2 and BnGS1-2 were closely related to those of legumes, alfalfa (Medicago sativa), soybean (Glycine max) and bean (Phaseolus vulgaris). The BnGS gene expression patterns revealed that each gene exhibited similar organ specificity, but distinct transcript intensity during different vegetative processes. The relatively abundant expression of BnGS1-1 and BnGS2 at specific organs during different vegetative processes indicates that they have critical roles in nitrogen uptake and assimilation relating to forage and growth characteristics. The BnGS1-2 mRNA levels were remarkably upregulated in the phloem, xylem and stems during the fiber development stage, suggesting a correlation with fiber development. Therefore, the non-overlapping transcript intensity of BnGS genes in different tissues regulates ramie growth and development during different vegetative processes.
