“…They are made of multifunctional materials consisting of two or more chemically distinct constituents, having a distinct interface separating them. The discontinuous phase is embedded in a continuous phase to form the composite [1]. A polymeric blend is a material formed from the physical combination of at least two polymers.…”

“…A single large part made of composites can replace many metal parts. [1]. The importance of fibers in a composite material is to provide a framework of support and strength to the weak polymer matrix and the need to attain a set of desirable properties; the fibers must consist of properties such as high elastic modulus, good stiffness, and compressive strengths [3], [4].…”

“…Moreover, the matrix is the base material, while the fiber is what reinforces the polymer material in the development of coir fiber composites and has recently gained attention due to its low cost, easy availability, low density, ease of separation, biodegradability, recyclable in nature [1]. Due to its strong yet flexible properties, Fiber reinforced polymer (FRP) can replace materials like wood, aluminum, granite, and steel [8].…”

“…When designed in a proper way, the new combined material exhibits good properties, which can be better than the individual material [17]. Continuous fiber reinforcement like silicon carbide (SiC), high strength carbon fibre is of low-cost, high-performance reinforcements for Aluminum matrix composites since it possesses high temperature stability and it is compatible with molten aluminum [1]. It is noted that fiber content coconut composite has improved the tensile strength but reduced the ductility of the matrix due to the better adhesion inside the composite.…”

Composite material using coconut fiber to produce reinforced low-density polyethylene (LDPE) composite was produced for evaluating of the effect of varying fiber sizes on the mechanical (tensile, hardness, and impact strength), water absorption, and chemical resistance properties of the developed LPDE. Sample categories were prepared by varying the fiber sizes below 2.36 mm, ≥ 2.36 mm, and ≥ 3.35 mm at a constant 5% volume fraction loading. The water retting process was applied in the extraction and cleaning of the coconut fiber (or coir), while the developed composite material was prepared using the Hand layup Technique (HLT). The tensile and hardness properties were tested using the Universal Testing Machine (UTM) Model BDUM-2.5KN, while the impact properties were tested using the Izod Impact testing machine Model RI-300. The analysis of the water absorptivity showed that the developed composite materials have a low water absorptivity of 2% at fiber size loading below 2.36 mm. However, at higher fiber sizes of ≥2.36 mm and ≥3.35 mm loading, the water absorptivity increases significantly to 5.8% and 7.9%, respectively. Test results showed that the composites produced with fiber sizes less than 2.36 mm fiber loading has the most optimum combination of tensile and hardness properties, of 25.20Mpa and 22.96Mpa respectively but have the least impact strengths of 229 joules as compared to other sizes. It is recommended to use the hand layup technique for the production of low density polyethylene composites and this could further be used as an additive for the production of some lightweight polymer materials such as packing tools, furniture designs for tabletop, windows, door frames, cloth pegs, stool top, since its hardness, low strength, non-structural application, and moisture resistance analysis is within the acceptable limit of application for this purpose while eliminating pollution by using the waste sachets and nylon.

The need to comply with environmental regulations and provisions set by the government for sustainability and environmental awareness has caused the use of natural fiber‐reinforced composites in the automotive industry to increase. Furthermore, there has been a lack of extensive research on the production of eco‐friendly composites for automotive applications utilizing epoxy resin, rice husk, Al2O3, and Fe2O3 by the compression molding technique. Therefore, the objective of this study is to determine the influence of compression molding pressure on the properties of eco‐friendly composites for automotive applications. The specimens consisted of epoxy resin, rice husk, Al2O3, and Fe2O3, in that order by weight percentages of 50%, 20%, 15%, and 15%, respectively. Compression molding with pressures of 10, 20, and 30 MPa and a holding time of 20 min at room temperature was utilized in this study. To evaluate the properties of the obtained specimens, density, hardness, flexural, wear, TGA (thermal gravimetric analysis), and DSC (differential scanning calorimetry) tests were conducted. The research findings show that composite specimens' physical and mechanical properties decrease while the friction coefficient increases with increasing pressure during compression molding. In contrast, the pressure increase did not significantly alter the thermal characteristics of the composite specimens. The BP_10 specimen, fabricated at a molding pressure of 10 MPa, exhibited superior properties compared to other specimens. Density, hardness, flexural strength, coefficient of friction, total residue, Tmax, Tg, and Tc in specimen BP_10 was 1.881 g/cm3, 80.5 shore D, 35.84 MPa, 0.262, 58.67%, 354.87, 285.53, and 497.7°C, respectively.Highlights The demand for natural fiber‐reinforced composites is increasing because more vehicles are on the road. The properties of natural fiber‐reinforced composites are strongly influenced by the pressure applied during compression molding. Results show that compression molding pressure strongly influenced the hardness, density, flexural strength, friction coefficient, and thermal stability of natural fiber‐reinforced composites. The natural fiber‐reinforced composites developed in this research can contribute to several Sustainable Development Goals (SDGs).
