Rice straw and energy reeds fiber reinforced phenol formaldehyde resin hybrid polymeric composite panels

Abstract

Herein, natural fiber (energy reeds and rice straw) reinforced with phenol formaldehyde (PF) polymeric resin hybrid biocomposites are developed and reported in this study. The dimensions of energy reeds and rice straws used for this research were 0.5 to 1.66 mm and 0.1 to 3.55 mm, respectively. The hot-pressing technology was used for manufacturing the biocomposites. The proportions for mixing of rice straw/energy reeds in composite systems were 90/0, 54/36, 36/54, and 0/90, whereas another 10% were PF resin. The nominal densities of the biocomposite panels were 680 kg/m3, however the actual densities were 713.655, 725, 742.79, and 764.49 kg/m3. The main objective of this study is to develop hybrid biocomposites from different proportions of energy reeds and rice straw fibers and to find the convenient ratio and materials for biocomposites production. The obtained results demonstrate that mechanical properties and stability against the moisture increases with the increase of energy reeds loading in the composite systems. However, the biocomposite developed from 100% energy reeds provided the higher mechanical properties compared to 100% rice straw. The mechanical, physical, thermal, and morphological properties of the produced biocomposite materials were investigated. Moreover, the overall thermomechanical performances of the developed biocomposite panels demonstrate a potential and novel materials in the coming times. Furthermore, the coefficient of variation (R2) also demonstrates a positive attributions of energy reed fibers loading inn composite systems.

Novel insulation panels development from multilayered coir short and long fiber reinforced phenol formaldehyde polymeric biocomposites

“…Thermal conductivity was characterized as per standard procedures of MSZ EN ISO 10456. Our previous studies provided detailed discussions of different cellulosic material reinforced composites [24,44]. The mechanical properties, in terms of flexural performances and internal bonding strengths, were tested using Instron testing equipment (4208, USA).…”
