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.

“…The FTIR spectra of N-EFB and Gly-EFB did not show any significant different from one to another. Both spectra showed disappearance of peak at 1700 cm -1 due to removal of hemicellulose [16].…”

“…However, intensity of this peak decreased after treatment. This was contributed to small portion of lignin that has been partially released into the filtrate [16]. An absorption band at 897 cm −1 was assigned to C-O-C stretching at the β-(1, 4)-glycosidic linkage in cellulose [14].…”

Abstract. In the present work, two types of treatment namely alkaline hydrolysis and glycerolysis have been conducted for lignin extraction from oil palm empty fruit bunch (EFB) fiber. Lignin has been retrieved from two sequential methods, which was the klason lignin from residue and lignin from precipitation of the filtrate. Alkaline hydrolysis was performed using 10% NaOH solution at room condition. This has extracted 13.0 % lignin. On the other hand, glycerolysis was carried out using 70% glycerol catalyzed with 5% of 1 M NaOH at 60-70 °C. This has successfully extracted 16.0% lignin. The SEM micrographs exhibited some physical changes on the surface where the impurities and waxes have been removed, exposing the,lumen. Besides that, FTIR analysis was conducted on untreated EFB, treated EFB and extracted lignin. Delignification of EFB fiber was confirmed based on the intensity reduction at 1245 cm -1 that showed lignin was removed from the fiber. The presence of C=O, C=C and C=C aromatic peaks in the FTIR spectra of the dried filtrate gave an evidence on the presence of lignin.

Mechanical Properties of Woven Mat Jute/Epoxy Composites

et al. 2016

Natural fibers combine technological, economic and ecological aspects. However, a major restriction on their successful use in long term composite applications is their high moisture absorption and poor dimensional stability. This paper is aimed at establishing a link between the mats grammage and the mechanical properties of the epoxy/jute fibers laminates. Composites reinforced by coarse, medium and fine (C, M and F) mats were processed by vacuum bagging. Some batches were immersed in water up to 60 days in order to study the hydro-degradation. Mechanical tests were performed to obtain the bending strength and impact response. The mechanical response to bending and impact loadings was conditioned not only by the percentage of fiber, but also by the thickness of the specimens, which leads to composites F having lower strength than composites C despite having a higher percentage of fiber. Immersion in water causes a marked loss of mechanical properties in the first days of immersion, especially for thinner fiber grammage composites. A strong influence of the mats grammage on the impact response was observed. Increasing mats grammage promotes a strong increase in peak load, restored energy and impact energy for perforation and also a marked reduction of the deformation.
