TL;DR: In this article, a sisal composite with polypyrrole/polyaniline via in-situ chemical oxidative polymerization technique was used for reactive orange 5 elimination from aqueous media.
Abstract: Sisal is a natural fibrous low-cost biomaterial that is frequently found in the surrounding environment and has no toxic effects. To upgrade its performance and applicability, sisal was modified with polypyrrole/polyaniline via in-situ chemical oxidative polymerization technique for reactive orange 5 elimination from aqueous media. Nowadays, dye pollution and its subsequent adverse effects have been of great concern for all around the world. The prepared composite was characterized by SEM, FTIR, and XRD analysis; they indicated that the polypyrrole and polyaniline were successfully coated on sisal. Optimum contact time was found at 120 min, and at the adsorbent dosage of 200 mg, almost 97 % of dye was removed. At low dye concentration (5−10 ppm), the efficiency of the sorption system was significantly acceptable (99 %). pH 2 had the maximum adsorption capacity due to attraction between negatively charged dye and positive nature of sisal composite. In view of thermodynamics, the process was endothermic and so better removal was observed at 45 °C. Langmuir/Freundlich and Pseudo-second order could satisfactorily expound the sorption system with R2 values of greater than 0.99, exhibiting that physisorption/chemisorption occurred. Sisal/polypyrrole/polyaniline was more than 5.69 times effective than raw sisal for dye adsorption. In the case of synthetic wastewater, the removal efficiency reached 81 %. Hence, the low-cost sisal/polypyrrole/polyaniline composite was a promising alternative for reactive orange 5 removal.

TL;DR: In this paper, the second layer polyester composites reinforced with 10, 20, and 30 vol. % of sisal fibers were evaluated using class III 7.62x51 mm ammunition, based on the NIJ 0101.06 backface signature methodology.
Abstract: The urban violence and the different types of global armed conflicts demand efficient protective systems against high energy ammunition. Multilayered Armor Systems (MAS) provide efficient protection by making use of lighter and more efficient materials. A typical MAS may be composed of three layers: a front ceramic followed by a composite, backed by a ductile metal. Polymer composites reinforced with natural fibers have proven to be effective second layers, being also lighter, low-cost and environmentally friendly as compared to conventional composites like KevlarTM. The present work evaluates MAS using as second layer polyester composites reinforced with 10, 20, and 30 vol. % of sisal fibers. Ballistic tests were performed using class III 7.62x51 mm ammunition, based on the NIJ 0101.06 backface signature methodology. Both the 30 vol.% sisal fiber composite and the conventional aramid laminates were equally efficient in terms of MAS second layer. The explanation might be the similar capacity of the different composites to retain the fragments generated by the interaction of the projectile with the front ceramic, independently of the percentage of sisal fibers.

TL;DR: In this paper, the water absorption behavior of sisal fiber reinforced benzylated fir sawdust composites is discussed and the inherent biodegradability of the raw materials of the all-plant fiber composites proves to be retained.
Abstract: Sisal fiber reinforced benzylated fir sawdust composites belong to a new category of composite materials, in which both the reinforcement and matrix are based on plant fibers, i.e. renewable resources. The present paper discusses the water absorption behavior of the composites and its influence on the mechanical properties of the composites. In addition, biodegradability of the composites is assessed by using enzyme and fungi tests, respectively. The experimental results indicate that water absorption behavior of the composites is mainly controlled by the reinforcing fiber and the fiber/matrix interfacial characteristics. The inherent biodegradability of the raw materials of the all-plant fiber composites proves to be retained. During the tests of enzymolysis and biodeterioration in soil, damage of the composites was initiated either inside the sisal fiber or at the surface of the composites.
