“…Li and co-workers [ 213 , 214 , 215 ] investigated the effects of chelators, white rot fungi, and enzyme treatments towards hemp fiber separation from bundles and enhanced the hemp fibers’ interfacial interaction with the PP matrix. The findings indicated that treated fiber composites had a greater interfacial shear strength than untreated fiber composites, a conclusion that was corroborated by a large body of literature [ 92 , 174 , 216 , 217 , 218 , 219 ]. This demonstrates that the white rot fungal treatment increased the interfacial attachment of hemp fiber to PP.…”

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.

The study investigates the mechanical, and tribological properties of Al6061-SiC-NSA hybrid composites. The characterization via FE-SEM reveals NSA particle’s crystal structure and agglomeration, with an average particle size of approximately 400 nm. The EDS analysis confirms the presence of oxides (TiO2, SiO2, Fe2O3, Al2O3) along with calcium and potassium. The XRD spectra corroborate these findings, additionally identifying Calcite and intermetallic compounds. The Al6061-5SiC-10NSA composites has improved compressive strength of 254 MPa compared to 220 MPa for base Al6061 alloy. The tensile strength of base Al606 (100 MPa) decreased to 70 MPa for Al6061-5SiC-20NSA composites. The tensile strength decreases with increasing NSA content. Fracture analysis indicates ductile fracture mechanisms, supported by FE-SEM images displaying honeycomb-like structures and dimples. Impact testing reveals reduced impact strength in composites compared to Al6061 (26J3), with Al6061-10SiC-5NSA exhibiting the best toughness of 22.5 J3. Density decreases in composites, with density of Al6061-5SiC-20NSA composites has reduced to 2.40 g/cm3. The microhardness of Al6061-10SiC-5NSA has better value of 109 HV, whereas further addition of NSA has resulted in decrease in microhardness of composites. Pin-on-disc wear tests demonstrate improved wear resistance with increased NSA content, with Al6061-5SiC-20NSA outperforming other compositions. COF decreases with increased NSA content and sliding speed. FE-SEM analysis of worn surfaces reveals that the major wear mechanism is adhesive wear followed by delamination, further the oxide formation along the surface aiding wear resistance of the composites. Tafel testing indicates decreased corrosion potential with increased NSA content, with Al6061-5SiC-20NSA exhibiting improved corrosion resistance.

Aluminium-based composites are extensively employed for high-performance applications in the automotive and aircraft industries on the basis of their superior mechanical characteristics comprising light weight, high specific strength and excellent malleability. Different metals and alloys are fabricated as composites using various combinations of materials with various fabrication methods. The current article explores a detailed overview of the methodologies, including solid, semi-solid, liquid and vapour routes, adopted by many researchers for the synthesis of reinforced aluminium-based materials. The influence of reinforcement in terms of natural resources and industrial waste considered recently is briefly discussed. Based on the literature review, research work has also focused on exploring the most economical and frequently employed synthesis methods for the fabrication of aluminium matrix composites.
