“…The increasing trend in flexural modulus as flour content of lemongrass fiber increased was anticipated because of the subsequent increase in stiffness of the reinforced polymer matrix. The present finding is in close agreement with other reports in the literature (Shibata et al 2006;Reddy et al 2010). …”

“…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).…”

Preparation and Characterization of Lemongrass Fiber (Cymbopogon species) for Reinforcing Application in Thermoplastic Composites

et al. 2017

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.

“…Accordingly, extensive studies on the attractiveness of a plant based fiber reinforcement materials come from its low abrasion, multifunctionality, low density, unlimited availability, ecofriendliness, high specific mechanical performance, and renewability [8][9][10][11][12][13][14][15][16]. These properties have made fibers very attractive candidate material for many applications such as automotive, building, construction, and aerospace.…”

The effect of surface treated sisal fiber on the mechanical, thermal, flammability, and morphological properties of sisal fiber (SF) reinforced recycled polypropylene (RPP) composites was investigated. The surface of sisal fiber was modified with different chemical reagent such as silane, glycidyl methacrylate (GMA), and O-hydroxybenzene diazonium chloride (OBDC) to improve the compatibility with the matrix polymer. The experimental results revealed an improvement in the tensile strength to 11%, 20%, and 31.36% and impact strength to 78.72%, 77%, and 81% for silane, GMA, and OBDC treated sisal fiber reinforced recycled Polypropylene (RPP/SF) composites, respectively, as compared to RPP. The thermogravimetric analysis (TGA), differential scanning calorimeter (DSC), and heat deflection temperature (HDT) results revealed improved thermal stability as compared with RPP. The flammability behaviour of silane, GMA, and OBDC treated SF/RPP composites was studied by the horizontal burning rate by UL-94. The morphological analysis through scanning electron micrograph (SEM) supports improves surface interaction between fiber surface and polymer matrix.

Degradable Nursery Containers Made of Rice Husk and Cornstarch Composites

et al. 2016

The degradation behavior was investigated for eco-composite nursery containers (NCs) prepared with rice husk and cornstarch adhesive modified with urea formaldehyde (UF) as a wet strength agent. The wet shear strength, water absorption capacities, and biological degradation of NCs within soil were also investigated. Quantitative analysis of the thermal degradation behavior of different NC versions was performed by thermo-gravimetric analysis (TGA). The results demonstrated that the introduction of the UF agent accelerated the soil degradation of the NCs matrix to a certain extent. The maximum cumulative mass loss was 51.1% when the UF content of NCs was 8 wt.%. Moreover, the dry strength of the mixed urea formaldehyde-cornstarch adhesive (UCA) was increased by 108.9% compared with cornstarch adhesive (CA). The results of this work indicate the improved biodegradability of the NC ecocomposites, which could make them potential sustainable alternatives for conventional plastic pots.
