“…The cellulose chains are distributed into amorphous (disordered) and crystalline (ordered) regions (Moon, Martini, Nairn, Simonsen, & Youngblood, 2011), and the former is commonly removed by chemical treatments. Cellulose can be processed (mechanically or chemically) for the extraction of nanofibers (CNF), nanocrystals (CNC), microfibrils (MFC) or microcrystalline cellulose (MCC), and all of them have been investigated as reinforcement in epoxy composites (Ansari, Sjöstedt, Larsson, Berglund, & Wågberg, 2015;Habibi, Lucia, & Rojas, 2010;Vijay et al, 2020).…”

Cellulose and its derivatives are widely explored for films and thickening of pharmaceutical solutions, in paints, as reinforcement in composites, among others. This versatility is due to advantages such as renewability, low cost, and environmental friendliness. When used in polymer composites, due to the hydrophilic character of the cellulose, surface chemical modification is highly recommended to improve its compatibility with the polymeric matrix. Hence, this paper presents a systematic review of chemically modified cellulose/epoxy resin composites focusing on the last five years. The investigation followed the PRISMA protocol that delivers a meticulous summary of all available primary research in response to a research question. After including/excluding steps, thirty-six studies were included in the review. The results were presented focusing on thermal, mechanical and dynamic-mechanical properties of the composites. In brief, this methodology helped identifying the main gaps in knowledge in that field.

“…Figure 3 shows the FTIR plots of BBF, virgin PLA, and the BBF/PLA composite. From the FTIR of BBF, the peaks were found at the wave numbers of [ 47 ] 3412, 2919, 1737, 1626, 1425, 1383, 1323, 1247, 1117, and 615 cm −1 . The peaks at 3412, 2919, and 1425 cm −1 belong to the OH group, the CH group, and the CH 2 group, respectively, which confirm the presence of cellulose.…”

Biocomposites have attracted researchers recently due to their biodegradability and environment-friendly nature. The application of new fibers is increasing to reduce the fiber cost, and easy processing, and to meet the applicationspecific properties in composite manufacturing. Banana is one of the most investigated plants for extracting fibers. Literature showed that the banana fibers were extracted from various parts of the plant. However, the potential of banana bracts is not discovered yet for composite manufacturing. In this work, the Robusta (AAA) variety banana bracts fibers (BBF) were prepared and used to make BBF reinforced polylactic acid (PLA) matrix biocomposites. Virgin PLA and BBF/PLA composites were prepared by two roll mills followed by compression molding. The characterization was carried out through X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), and the tensile, flexural, and impact properties were evaluated for Virgin PLA, BBF, and BBF/PLA composites. The FTIR results supported the incorporation of banana bracts in the composites by increasing the cellulosic and noncellulosic components. The SEM images supported the bonding of BBF in the PLA matrix. The BBF/PLA composite possessed the tensile strength of 40.15 ± 4.32 MPa, flexural strength (FS) of 87.13 ± 5.60 MPa, impact strength of 7.41 ± 0.56 kJ/m 2 , and a crystallinity index of 48.22%, which were significantly better than the virgin PLA. It was concluded that the BBF can be effectively used for making biocomposite with good mechanical strength.banana bracts, biocomposite, green composite, natural fiber, PLA | INTRODUCTIONNatural fiber-based biocomposites have replaced synthetic fiber-based polymeric composites as a research focus because of environmental and ecological concerns.

“…The modifications of silane and NaOH to the fiber resulted in reductions in diameter of 9.17% and 17.43%, improvements in a crystalline index of 41.01% and 14.86%, improvements in thermal stability of 14.15% and 4.81%, and increases in tensile strength of 37.75% and 28.92%, according to the data. The entire investigation showed that silane treatment was superior to NaOH treatment and utilizing raw fibers for Muntingia calabura microfiber [16,17]. In comparison to untreated and KMnO 4 -treated Calotropis gigantea fibers (CGF) composites, results showed that NaOH-treated CGF composites displayed improved tribological behavior [18].…”

The addition of nanofillers in the polymer matrix composites (PMC) has shown a considerable improvement in the mechanical properties and acts as a suitable replacement material. Among the various properties, erosion studies play a key role in the establishment of new materials in engineering applications irrespective of material properties. This paper primarily focus on mechanical properties of PMC and provides a view of the erosion studies conducted on various PMC that are reinforced with natural fibers and nanofillers. The study related to natural fiber as secondary reinforcement and nanofiller as primary reinforcement is taken into consideration. The natural fibers such as sisal-, pineapple-, jute-, bamboo-, banana-based polymer composites and their improvement in mechanical properties by the addition of various fillers are compared and reported. From the survey, it was noticed that the incorporation of nanofillers with natural fiber and polymers provides an acceptable range of material behavior. Being the natural fiber and its proper surface treatment enhance erosion resistance behavior.
