“…73 KNF/CF-SAN composites are based on MA functionalized SAN (CF-SAN) and similar adhesion has also been observed for the other MA functionalized polymer based composites by Palsule process. [19][20][21][22][23][24][25][26] These observations also confirm the successful formation of the KNF/CF-SAN composites; with the reinforcing natural KN fiber retaining its stability during processing even at relatively higher temperatures. This thermal stability is also investigated and reported later in this study.…”

“…The esterification, possibly results in the formation of, both, the monoesters and also the diesters, that have been recorded to form at higher temperatures. 77,78 Mono and di esters, both, have also been recorded for the bagasse fiber reinforced MA functionalized SEBS composites 26 that have also been developed by the same Palsule process that is used in this study and this study also uses MA functionalized SAN (CF-SAN).…”

“…For example, alkali and silane treatment (AST) functionalized pistachio shell fibers (PSF) have been used as reinforcements for MA functionalized PLA matrix based AST-PSF/PLA-MA biocomposites. 18 In the composites by Palsule process based on MA functionalized matrix polymers, 16,[19][20][21][22][23][24][25][26] the esterification reaction between the MA of the matrix polymer and the functional -OH of the natural fiber; and hydrogen bonding between them imparts adhesion between them. This well established mechanism 16,[19][20][21][22][23][24][25][26] has also been reviewed recently.…”

“…For example, HDPE composite 19 and PP composite 21 by Palsule process showed better performance than the same HDPE composite and the same PP composite by the other two processes, as compared in Ref 19 and Ref 21 respectively. Palsule process has been used to develop the composites based on the following MA functionalized (CF) polyolefins: CF-PE 16,19,20 and CF-PP [21][22][23] and also thermoplastic elastomers, CF-EPR 24,25 and CF-SEBS 26 and also for the following GMA functionalized polymer: CF-VLDPE. 28 Although the techno-economic advantages of the Palsule process make it a preferred process, however, the process has been used only for the composites that can be processed at a relatively lower processing temperature only; and the functionalized matrix polymers used, have functional groups grafted on them with the amount of functionality being less than 5%.…”

In view of no reports on natural fiber reinforced functionalized styrene acrylonitrile composites, this study develops kenaf fiber (KNF) reinforced chemically functionalized styrene acrylonitrile (CF-SAN) composites (KNF/CF-SAN) by extrusion and injection molding. The selected CF-SAN matrix is a chemically functionalized random ter-polymer, with high (10 ± 2%) maleic anhydride functionality and requires higher processing temperature. With respect to CF-SAN, the 10/90, 20/80 and 30/70 KNF/CF-SAN composites show 25%, 46% and 75% higher tensile modulus, 23%, 55% and 78% higher tensile strength, 34%, 66% and 104% higher flexural modulus and 48%, 87% and 125% higher flexural strength. Relative to the dry matrix, the water absorbed composites show higher properties, but relative to the respective dry composites, the water absorbed composites have at least 7% lower tensile strength and at least 20% lower tensile modulus, flexural modulus and flexural strength. SEM and FTIR (ATR-IR) establish that hydrogen bonding and esterification by Palsule process impart CF-SAN/KNF adhesion and bonding in the composites. The composites show thermal stability between KNF reinforcement and CF-SAN matrix upto 295°C.

Coir fiber (COIRF) reinforced glycidyl methacrylate (GMA) functionalized ethylene butyl acrylate (CF‐EBA) composites (COIRF/CF‐EBA) were processed by extrusion and injection molding. A good COIRF/CF‐EBA interfacial adhesion was indicated by Scanning Electron Microscopy (FE‐SEM). Fourier Transform Infra‐Red (FTIR) spectroscopy established this adhesion emerging from etherification and hydrogen bonding between the functional groups of CF‐EBA and of COIRF. The composites exhibited higher tensile properties than pristine CF‐EBA, and also exhibited increase in their tensile properties with increase in COIRF contents in them. The storage modulus and loss modulus of the composites also increased as the amount of COIRF in them increased, but the values of these properties decreased with increasing temperature. Thermal stability of the composites was observed to be intermediate between that of COIRF and CF‐EBA.Highlights Coir Fiber/Chemically Functionalized Ethylene Butylene Acrylate Composites. CF‐EBA/COIRF bonding by etherification and hydrogen bonding between them. The COIRF/CF‐EBA composites show higher properties than their CF‐EBA matrix. 30/70 COIRF/CF‐EBA composite showed the highest tensile strength (10.93 MPa). COIRF/CF‐EBA composite show thermal stability upto approx. 245°C.

The demand of natural fiber reinforced composites has grown enormously in polymer industries owing to their renewability and sustainability and maintaining their performance and properties. In this investigation, two natural fibers have been considered as a reinforcer to develop chemically functionalized high‐density polyethylene (CF‐HDPE)‐based composites. The total holocellulose content of ~85% and ~65% for nettle fiber (NTF) and oil palm empty fruit bunch fiber (OPF) make them significant for this study. OPF/CF‐HDPE and NTF/CF‐HDPE composites have been developed and characterized to measure their desirable properties. The structural confirmation suggests reinforcement/matrix adhesion through ester and hydrogen bonds between them. NTF/CF‐HDPE and OPF/CF‐HDPE are thermally stable upto 240°C and 250°C, respectively. A significant increment of ~40% and ~64% in tensile strength were observed in addition of OPF and NTF reinforcer in pristine matrix. A similar observation has been shown in flexural strength with improvement of ~58% and ~83% with OPF and NTF as reinforcer. Among all these composite compositions, the 30/70 NTF/CF‐HDPE composite demonstrated the highest tensile and flexural properties values due to higher holocellulose of NTF. This study demonstrates the potential of OPF and NTF reinforcer to develop natural fiber reinforced polymer composites, which helps respective industries to manufactured tailored made products with desirable properties.Highlights OPF/CF‐HDPE and NTF/CF‐HDPE composites are sustainable and low cost. The composite compositions have been developed by extrusion and injection molding. The composite's mechanical (tensile and flexural) properties have been demonstrated. SEM and FTIR characterized the composites for the fiber/matrix adhesion. The composite's thermal stability has been affected by fibers and matrix.
