“…These fiber reinforcements improve the mechanical strengths and thermal stability of the composites (Panthapulakkal et al 2006;Alemdar and Sain 2008;Zou et al 2008;Mominul et al 2009;Ravindra et al 2010;Arrakiz et al 2013). Most studies have demonstrated that natural fiber reinforcement in polymer matrices substantially improves the desirable characteristics of composite materials in engineering applications, demonstrating the advantages of these fibers over synthetic glass and carbon fibers (Panthapulakkal et al 2006;Jayamani et al 2015).…”

Lemongrass fiber was analyzed to determine the chemical proportion of its lignocellulosic components. Fibers' thermal behavior, surface structures, and functionality were assessed by thermogravimetric analysis (TGA), scanning electron microscope (SEM), and Fourier transforminfrared spectroscopy (FT-IR), respectively. High-density polyethylene (HDPE) matrix composites filled with varying (10%, 20%, 30%, 40%, and 50%) fiber content were prepared and investigated. Composite wicker was made from HDPE and low density polyethylene (LDPE) blend-matrix and 10% alkaline modified fiber. Alkaline or maleic anhydride grafted polypropylene (MA-g-PP) was used to improve the compatibility between the fiber and matrices. The composites were evaluated by using TGA, SEM microscopy, and universal testing machine, respectively. The fiber was constituted by equitable amounts of lignocellulosic components with cellulose accounting for the highest proportion. It also exhibited high degradation temperature, which was further increased following alkaline modification. Superior thermal degradation behavior was measured for modified fiber composites. SEM showed that the modified fiber composites demonstrated better compatibility. Lemongrass fiber reinforcement substantially improved the mechanical properties of the composites.

“…Agro-based material, such as straws and stalks are also sources of cellulose-based fibers which are increasingly considered as low-cost potential alternatives to wood fibers,although they have lower cellulose content compared to wood [5].Fibers with higher cellulose content, i.e. higher degree of polymerization of cellulose and lower microfibrillar angle, render better mechanical properties.…”

Abstract.Ecological concerns and the impending depletion of fossil fuels are driving the development of new bio-based, green products. Natural fibers are used increasingly as a filler or reinforcement in commercial thermoplastics due to their low cost, high specific properties and renewable nature. Agricultural byproducts and wastes are excellent alternative materials to supplement or substitute wood material as a reinforcement in composites.This comparative study focuses on the effects of the substitution of wood fiber with agro-basedfiber (barley straw) on the mechanical and physical properties of natural fiber/polypropylene composites. The studied mechanical properties are flexural strength and modulus, Brinell hardness and Charpy impact strength. Water absorption and thickness swelling are studied as physical properties. Generally, the research resultsindicate that almost all the studied properties weakened significantlyas woodwas substituted with barley straw.Ofmechanical properties, the major decrease wasobserved in hardness.However, the use of barley straw slightlyimproved impact strength.The moisture-related properties, water absorption and thickness swelling,which have a great impact on the durability of a composite material, weakened significantly.

“…Koszty sorpcji zależą głównie od ceny i wydajności sorbentu. W przypadku usuwania z roztworu P-PO 4 sorbent powinien posiadać w roztworze wodnym ładunek dodatni, ponieważ oddziaływanie elektrostatyczne między anionami sorbatu a dodatnio naładowaną powierzchnią sorbentu zwiększa skuteczność sorpcji [Panthapulakkal et al 2006;Xu et al 2011].…”
