The study utilized rice husk filler (RHF), Cinnamon inner filler (CIF), and Syzygium grande filler (SGF) as hybrid materials in producing laminated ramie/epoxy composites. The composites were created by manually stacking woven ramie fibre with natural fillers with mesh sizes 100 and varying concentrations. This study conducted tests to evaluate composite materials' tensile, flexural, and impact properties and examine how adding fillers affects these properties. The result showed that the concentration of fillers at 10 wt.% has achieved the highest tensile properties compared to other concentrations. Cinnamon inner filler composites had the maximum tensile strength among the various filler materials. Compared to all the different hybrid samples, adding CIF in woven fibre had the highest tensile strength of 36.25 MPa, flexural strength of 52.27 MPa, and impact strength of 0.337 J. This may be due to the compatibility between cellulose fibres, CIF, and epoxy matrix. The utilization of an optical microscope facilitated the investigation. It revealed that enhanced blending of the cinnamon filler within the composites resulted

It has several advantages when used as a reinforcement in polymer composites caused by its great mechanical performance, increase cellulose content, low cost, and abundant availability. It is important to note that the structure of the fibers used as reinforcing materials is a critical aspect of fabricating a strong polymer composite. Therefore, this study was conducted to determine the effects of layering as well as fiber orientation towards the mechanical characteristics of woven abaca-reinforced epoxy composites. Furthermore, this comprised the application of hand lay-up technique as well as hydraulic press molding in producing 2, 3, and 4 layers of woven abaca-reinforced epoxy composites after which the mechanical properties were analyzed based on its orientation in the warp and weft direction. The results showed that an increase in the number of layers from 2 to 4 did not affect the tensile and flexural properties at every layered stacking sequence of the fiber. Meanwhile, the material in the warp direction indicated a greater tensile as well as flexural properties in comparison to the weft direction. This means the number of layers and orientation of the woven abaca in epoxy composite possesses a significant influence towards the composites' mechanical properties.

In the current investigation, four distinct compounds were selected to identify the most effective combination for achieving the highest result of mechanical properties outcomes. Samples were created with variable RH concentrations (10%, 20%, 30%, and 40% by weight). The results showed that RH-RPP with 20% of RH had the highest mechanical properties. Scanning electron microscopy (SEM) images prove the enhanced mechanical characteristics. In addition, the water absorption and thickness swelling analysis show that RH-RPP composites with 20% RH concentration produce competitive results of 1.14% and 2.06%, respectively. Therefore, the finding from the present study summarized that the combination of RH and RPP with 20% of RH percentage had a great potential in producing competitive eco-friendly material for engineering applications especially for packaging materials. In addition, it is expected to provide an alternative for the management of crop waste and domestic plastic waste. Thus, able to
The microstructures and mechanical properties of aluminum matrix composites (AMCs) reinforced by ... more The microstructures and mechanical properties of aluminum matrix composites (AMCs) reinforced by varying weight percents of silicon carbide (SiC = 2.5%; 5.0%; 7.5 wt.%) combined with magnesium and zinc oxide nanoparticles using the stir casting method were investigated. The techniques of Optical Emission Spectrometer, optical microscopy, Vickers microhardness, and tensile test were used to characterize the aluminum hybrid composites. Fine microstructures and good consolidation were found for all samples, with microhardness values ranging from 107.04 to 151.54 HV and tensile strength ranging from 79.15 to 124.05 N mm-2. The research found that incorporating hybrid composites refined grain size and enhanced the tensile strength of the composite material. Furthermore, study findings also indicated that a higher SiC percentage enhanced the spread of grain sizes and promoted the formation of the Al-SiC-ZnO-Mg phase, leading to increased AMCs hardness and tensile strength.

It emphasizes the potential of these composites as a sustainable and cost-effective substitute in the automotive industry. Sawdust particles with a mesh size of 100 and weights of 10%, 20%, and 30% are mixed with epoxy resin in this experiment so that tensile stress and tensile modulus under load can be observed in detail. The fabrication process involved the manual lay-up of tensile specimens. The results indicate that the tensile properties of composites containing 20% sawdust are an unexpected 30% superior to those comprising 10% filler loading. In contrast, micrograph tensile fracture examinations unveiled the presence of agglomeration and air bubble, factors that compromised the accuracy of the findings. The results demonstrate the critical nature of optimizing the sawdust content to attain the optimal equilibrium in the mechanical properties of composites. It is recommended that future applications implement additional microstructural control measures and refine the fabrication process to enhance precision and dependability.
