“…In its glassy region, CF-EPR matrix shows higher E ′′ than of all the R-BMBF/CF-EPR composites in their respective glassy regions. This is similar to other composites, for example, natural fiber-reinforced thermoplastic biopolymer matrix composite of sisal fiber/PLA (SSLF/PLA) 40 and also the thermoset matrix composite of royal palm fiber/epoxy (RPF/EPX), 41 wherein the matrix polymers, PLA and epoxy, show higher E ′′ than the respective composites in the glassy region.…”

Recycled bamboo fiber-reinforced chemically functionalized ethylene propylene rubber (R-BMBF/CF-EPR) composites have been developed by extrusion and injection molding by Palsule process without any fiber treatment and without compatibilizer. Scanning electron microscopy (SEM) shows good R-BMBF/CF-EPR interfacial adhesion in the composites, and Fourier transform infrared (FTIR) confirms that esterification and the hydrogen bonding between functional groups of CF-EPR and of R-BMBF impart this interfacial adhesion. Mechanical, dynamic mechanical, and thermal properties and the effect of water absorption on tensile properties of the composites have been evaluated. Tensile properties of the 15/85, 25/75, and 35/65 R-BMBF/CF-EPR composites are higher than those of CF-EPR and increase with increasing R-BMBF in the composites. Storage modulus and loss modulus of the composites increase with increasing fiber contents in them but decrease with increasing temperature. Water-absorbed wet composites show thickness swelling and reduced tensile properties relative to the respective dry composites but higher tensile properties than the dry CF-EPR. Thermal stability and degradation of the composites is also reported.

“…It can be related to the improved interfacial adhesion after surface treatment of flax fibers; 33 however, oxidized flax fibers showed higher improvement due to the more effective silane treatment. 34 The storage modulus values of all composites sharply dropped at the temperature range of 40–70℃.

Natural fibers have been approved as an excellent alternative for traditional reinforcements in polymer composites. However, the main disadvantage of natural fibers as reinforcements is their poor interaction with polymeric matrices due to their hydrophilic nature. In order to improve their compatibility as composite reinforcement, surface treatments are required. Silane treatment has been widely used to modify hygroscopic properties of natural fibers. In this study, a new method of silane treatment has been developed without the prehydrolysis and curing/dehydration of silanol groups. To do so, flax fibers were modified through 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO)-mediated oxidation followed by direct application of the amino-silane. The fiber/matrix interfacial adhesion was examined by measuring interlaminar shear strength. Thermogravimetric analysis and dynamic mechanical analysis were performed to study the thermal resistance and thermomechanical properties of the composites. The results revealed that fiber/matrix adhesion was improved in the oxidized silanized fiber composite. In addition, water absorption was significantly reduced (20%) in the oxidized silanized fiber reinforced composite compared with the as-received one.

Due to the dominating advantages of natural fibres such as biodegradability, eco-friendliness, nominal cost, low density and high specific strength, they are being used opposite to synthetic fibres in many industrial applications. Despite many advantages, these fibres face some limitations such as higher moisture uptake, quality variations, low thermal stability, and poor compatibility with polymeric matrix. To overcome these limitations, chemical treatments of these fibres were found to be the most suitable method to improve adhesion with polymers, increase their strength and water absorption resistance, and improve their composite properties also. Among chemical treatments, alkali treatment is the most widely used and versatile surface modification method of the natural fibres. A good number of research works have been carried out on effect of alkali treatment on the properties of natural fibres and its composites, which motivated for this review. In this paper, the effect of alkali treatment on the properties of natural fibres has been reviewed. In addition, the physical and mechanical properties, thermal analysis and tribological behaviour of its biocomposites are also reviewed. It was concluded that alkali treatment of natural fibres could provide enhanced properties of various bio-composites up to a great extent.
