“…The literature shows that the alkaline treatment of natural fibre removed the hemicellulose layer from the surface of fibres [19,52]. In Fourier transform infrared spectroscopy (FTIR) analysis, the disappearance of the C=O stretching vibration of hemicellulose at 1750 cm −1 indicates the removal of hemicellulose that strengthens the fibre matrix interface, and results in improved mechanical properties of composites [53,65]. This finding is further validated by Figure 6, which shows that the alkali treatments removed impurities from the fibre surface, such as hemicelluloses and lignin.…”

Natural fibre-based materials are gaining popularity in the composites industry, particularly for automotive structural and semi-structural applications, considering the growing interest and awareness towards sustainable product design. Surface treatment and nanofiller addition have become one of the most important aspects of improving natural fibre reinforced polymer composite performance. The novelty of this work is to examine the combined effect of fibre surface treatment with Alumina (Al2O3) and Magnesia (MgO) nanofillers on the mechanical (tensile, flexural, and impact) behaviour of biotex flax/PLA fibre reinforced epoxy hybrid nanocomposites. Al2O3 and MgO with a particle size of 50 nm were added in various weight proportions to the epoxy and flax/PLA fibre, and the composite laminates were formed using the vacuum bagging technique. The surface treatment of one set of fibres with a 5% NaOH solution was investigated for its effect on mechanical performance. The results indicate that the surface-treated reinforcement showed superior tensile, flexural, and impact properties compared to the untreated reinforcement. The addition of 3 wt. % nanofiller resulted in the best mechanical properties. SEM morphological images demonstrate various defects, including interfacial behaviour, fibre breakage, fibre pullout, voids, cracks, and agglomeration.

“…Partially degradable alkali treated jute/epoxy based green composite, made by compression molding technic, was developed with different ranging NaOH concentration. This study revealed that successive alkali surface treatment improved the compatibility of jute fiber and epoxy matrix and effective stress transfer between the fibers and matrix [28]. Degradation is a process of breakdown of chemical particles by a biological environment.…”

Natural fiber composite is the novel materials in recent decades having a high strength to weight ratio and light in weight are widely used for structural and unstructured applications. Jute fiber is one of the most common biodegradable natural fibers which successfully replaced the synthetic fibers composite and also replaced glass fiber where the high strength is not obliged. Jute is grown in tropical countries and is one of the strongest bast fibers with low cost. Jute fiber composite has several attractive advantages over synthetic and glass fiber like as low processing cost, low density, stiffness and excellent mechanical properties. This advantage makes the jute a very attractive reinforced fiber for composites and increased attention in construction, automotive, aerospace and many others. This paper presented an overview on different jute fiber reinforced based polymer composites with mechanical characterization and their applications. The jute composites involving various thermoset, thermoplastics polymers, bio-based resins, jute hybrid composites and their mechanical properties are elucidated.

Recently, to improve the properties, reduce the amount of polymeric materials, the time of disposal in landfills and the cost of composite parts, the incorporation of vegetal biomass was considered. In this study, composites with 10% and 20% v/v of benzoxazine resins and macadamia nutshell (50#) were made via hand layup with in natura biomass and hydrothermally treated (121°C/45 min in an autoclave). Thermogravimetry indicates that the initial temperature of biomass degradation (209°C) allows it to be used with the resin (oven curing at 190°C). The enthalpies obtained from the DSC indicate that the percentage of cure increased with the biomass. FT‐IR tests indicate that the hydrothermal treatment collapsed part of the lignin and extracted lignocellulosic material. There was no significant modification of the glass transition temperature obtained in DMA and TMA with the introduction of biomass. Optical microscopy showed that the treated reinforcement showed a greater variation in size forming lumps. Based on these results, these composites can be used in the replacement of synthetic composites, contributing to a decrease in the consumption of petroleum derivatives and with this, reducing the disposal in landfills and dumps.
