“…On the other hand, the decomposition peaks of the polymeric matrices were also similar within each polymer group, without relevant difference related to the percentage of BF used, although it was found that these peaks were higher in the ABS and HIPS composites compared with the pure polymer. This behavior is in line with the results observed by Reddy et al [32], due to the interaction and synergies of the fiber-matrix that increase the degradation temperatures. However, HDPE-based compounds showed no change in degradation temperatures, explained by the minimal gas permeation barrier between fiber and polymer [33].…”

Several natural materials and vegetable waste have relevant mechanical properties, mainly in its fiber format. Particularly, banana fiber (BF) provides a close behavior to the widely spread glass fibers, which places it in an advantageous position for use as a reinforcing material in plastic composites. This work characterizes the behavior of acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS), and high density polyethylene (HDPE) reinforced with short fibers of bananas from the Canary Islands for its application in molding processes. Several thermal analyses (Thermal Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Melt Flow Index (MFI)) and mechanical tests (tensile, flexural, impact, and Dynamic Mechanical Analysis (DMA)) were carried out in composites with different percentages of banana fiber. The thermal results show that the use of banana fiber is viable as a reinforcement in composites for injection molding processes and the mechanical tests indicate an increase in stiffness and an improvement in maximum flexural stress by increasing the fiber content in composites, so the banana fiber turns out to be a natural alternative for the reinforcement of injected plastic components.

“…The OH stretching of hydrogen bond associated with hydroxyl group in the CTPFC leads to the transmittance peak detected in the wavelength region from 3550 to 3665 cm À1 . 29 The CH stretching vibrations associated with methyl and methylene groups found in cellulose and hemicellulose of the reinforced CTPF are responsible for the peak at ≈2930 cm À1 . Due to the presence of carboxylic acid and ester components in hemicelluloses, the strong peak at 1720 cm À1 corresponds to C═O stretchings of the carbonyl group.…”

The present work aims to investigate the potentiality of reinforcing coconut tree peduncle fiber an agro-waste with unsaturated polyester resin, optimizing its mechanical properties and promote as an alternative reinforcement to harmful synthetic fiber polymer composites. It was found that polymer composites with 40 wt% fiber content exhibited maximum mechanical properties and started to decline on further addition of fibers due to lack of sufficient resin to wet the fibers leading to fiber pull-out and debonding under applied loads. This was also evidenced from the observed micrograph of specimen undergone tensile failure.In addition, the chemical bonding between the fiber and matrix was confirmed through Fourier transform infrared analysis. Also, the thermal stability was ascertained by the degradation temperature obtained through thermo-gravimetric analysis. Moreover, the water absorption study in fresh and seawater exposed the pseudo-Fickian behavior and aquatic properties of the developed composite, which was further confirmed by the crystalline size obtained through X-ray diffraction analysis. The above holistic analysis of the fabricated composite ensures its sustainable use in automotive and marine industries.

The utilization of synthetic materials stimulates environmental concerns, and researchers worldwide are effectively reacting to environmental concerns by transitioning towards biodegradable and sustainable materials. Natural fibers like jute and sisal have been being utilized for ages in several applications, such as ropes, building materials, particle boards, etc. The absence of essential information in preparing the natural-fiber-reinforced materials is still a challenge for future applications. Chemical treatments and surface modifications can improve the quality of the natural fibers. Natural-fiber-based composites are a potential candidate for many lightweight engineering applications with significant mechanical properties. In the view of the progressive literature reported in the field, this work aims to present the significance of natural fibers, their composites, and the main factors influencing these materials for various applications (automotive industry, for instance). Secondly, we aim to address different surface modifications and chemical treatments on natural fibers and finally provide an overview of natural fiber reinforced polymer composites’ potential applications.
