“…Figure 6 showed that equal weight % share of PALF and sisal enhanced the overall mechanical attributes, e.g., ductile strength (207 MPa), bending strength (90.3 MPa), impact (29 J/m 2 ), and hardness (83.7). The mechanical test results revealed a regular trend of an increase in flexural, tensile, impact, and hardness with the addition of PALF fibers, and this was supported by various works [ 80 , 81 , 187 , 188 ]. Besides that, they concluded that this type of composite material could be valuable for multiple industries, including automotive and construction fields.…”

Increasing scientific interest has occurred concerning the utilization of natural fiber-enhanced hybrid composites that incorporate one or more types of natural enhancement. Annual natural fiber production is estimated to be 1,783,965 × 103 tons/year. Extensive studies have been conducted in the domains of natural/synthetic as well as natural/natural hybrid composites. As synthetic fibers have better rigidity and strength than natural fibers, natural/synthetic hybrid composites have superior qualities via hybridization compared to natural composites in fibers. In general, natural fiber compounds have lower characteristics, limiting the use of natural composites reinforced by fiber. Significant effort was spent in enhancing the mechanical characteristics of this group of materials to increase their strengths and applications, especially via the hybridization process, by manipulating the characteristics of fiber-reinforced composite materials. Current studies concentrate on enhancing the understanding of natural fiber-matrix adhesion, enhancing processing methods, and natural fiber compatibility. The optimal and resilient conceptions have also been addressed due to the inherently more significant variabilities. Moreover, much research has tackled natural fiber reinforced hybrid composite costs. In addition, this review article aims to offer a review of the variables that lead to the mechanical and structural failure of natural fiber reinforced polymer composites, as well as an overview of the details and costings of the composites.

Thermo‐mechanical properties of jute/bamboo/polyethylene hybrid composites: The combined effects of silane coupling agent and copolymer

The effects of 3-aminopropyl triethoxysilane (APTS) coupling agent and poly(ethylene-co-glycidyl methacrylate) (EGMA) copolymer on thermal, mechanical, and morphological properties of hybrid composites were investigated. There were a range of methods used to fabricate hybrid composites that included, untreated jute and bamboo fiber, APTS treated jute and bamboo fiber, and EGMA and low-density polyethylene (LDPE). The hybrid composites were characterized using Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). In addition, tensile strength, tensile modulus, surface morphology, and water absorption tests were also reported. The IR spectra of treated jutebamboo hybrid composite revealed effective removal of OH groups from cellulose fiber using APTS. Treated jute-bamboo/polyethylene composite (TJBC) and treated jute-bamboo/EGMA/polyethylene composite (TJBEC) demonstrate 3.8 times and 3.7 times higher activation energy, respectively. High activation energy implied that APTS coupling effect is dominant compared with EGMA copolymer. A marginal decrease in the crystallinity index (15.9%) was found in case of TJBC. The tensile strength and Young's modulus of the treated hybrid composites exceeded 150% and 330%, respectively. Low water absorption rate in the treated hybrid composites was also observed. Based on the routes chosen to treat the hybrid composites along with the outcomes of the tests conducted on these suitable for the nonstructural application, such as, packaging, site hoarding, furniture, industrial shelving, and lining for truck/ van cargoes.

In recent days, natural fiber reinforced polymer composite is more popular due to its extensive properties suitable for various potential applications. The attention towards natural fibers is because of low cost, biodegradable, recyclability, nonabrasive, combustible, lightweight, and nontoxic properties. However, there is a need for furthermore fundamental knowledge for the raw materials processing and fabrication of composite structures, which is still challenging in current days. Natural fiber sources exist all over the world, which is obtained from animals, plants and minerals. The quality of the natural fibers depends on the extraction methods and different processing techniques. These natural fibers surface characteristics could be enhanced by selecting suitable surface treatment and chemical treatment. These fiber treatments reduce the water intake percentage, improve the adhesive nature, and enhance the overall performance of resulting polymer composites. Among all the chemical treatments, alkaline treatment (NaOH) is the most preferred chemical treatment because of its effectiveness and its low cost. This review article proposes the natural fibers detailed classification, composition, structure, properties, and extraction methods, chemical and surface treatments. We also summarize the previous research work findings on the fibers treatment, properties of natural/natural hybrid polymer composites and natural/synthetic hybrid polymer composites with applications.
