“…The graph shows the most intense peak point of formation phase was observed at 2θ = 22°, and it is the type most intense peak point for crystalline structure, Figure 1. Moreover, the narrow and low peak that formed in the x-ray diffraction spectrum also proved that rice husk silica is in the crystalline form [18]. The formation peaks of quartz, cristobalite and tridymite made the peaks narrower and more intense, which reflects its high crystallinity.…”

Aluminium matrix composite is highly demanded in various industries due to its low density and good mechanical properties as most commonly studied for metal matrix composite. The properties of the composite be improved with the addition of reinforcement significantly such as silicon carbide, aluminium oxide, and boron carbide that can be mixed easily to metal matrix composite. The study of crystalline rice husk silica reinforced AA7075 aluminium chips on mechanical properties were investigated. The rice husk ash was burned at 1200 °C and it was characterized in the crystalline phase by conducting x‐ray diffraction test. The mechanical properties of aluminium matrix composite were obtained by microhardness and compression tests. Results of mechanical properties for the addition of rice husk silica up to 7.5 wt.% composition of crystalline rice husk silica showed increase value of microhardness and compression strength which are the highest value of 75.94 HV 0.1 and 443 MPa, respectively compared to another aluminium matrix composite. Hence, based on investigation to crystalline rice husk silica reinforced aluminium, it has good potential to improve the mechanical properties of aluminium matrix composite which were dependent to the composition of crystalline rice husk silica reinforcement in aluminium matrix composite.

“…Further some researches have extracted SiC from rice husk [33,34] and used that as a reinforcing material due to their better properties as comparison to RHA [35]. Joharudin et al [36], extracted silica from RHA through heat treatments and reinforced them in recycled Al7075 chip resulting into enhancement of the hardness of the developed composites.…”

Aluminum matrix composites (AMCs) have been extensively studied primarily due to higher strength-to-weight ratio, lower cost, and higher wear resistance properties. However, increasing demand for economical and energy-efficient materials in the automotive, aerospace and other applications is tailoring research area in the agro-based composite materials. Therefore, the aim of this systematic review work is to study the influence of agro-based reinforcements on the tribological and mechanical properties of AMC's processed by various techniques. It was observed that the processing conditions can be designed to obtain uniform structures and better properties AMCs. The agro-waste reinforcement materials, such as rice husk ash, bamboo stem ash, coconut and shell ash can result in a reduction in the density of AMC's without compromising mechanical properties. Moreover, the efficient utilization of the agro-waste leads to a decrease in manufacturing cost and prevents environmental pollution, hence, can be considered as a sustainable material. The state-of-the-art revealed that the agro-based reinforcements do not form brittle composites, as in the case of ceramic reinforced composites. Hence, the study concludes that the agrobased AMCs have great potential to act as a replacement for costly and environmentally hazardous ceramic reinforced-AMCs which can especially be used in various automotive applications that demand higher strength-to-weight ratio, lower cost, and higher wear resistance.

“…The production of these agricultural wastes has been researched to be applied in packaging systems because this product is more environmentally friendly and does not take too long to process. Rice husk [7][8][9] and coconut fibre [10][11][12][13] are agriculture waste materials that have proven to be used as cushioning materials. Rice husk is a valuable natural resource obtained from agricultural waste and has an annual global quantity generated of around 137 million tons.…”

In recent years, rice husk and coconut fibre started to have substantial commercial value in the industry due to the research being conducted on these agricultural wastes as a new raw material consisting of high fibres and abundant resources. Therefore, this investigation determines the suitability of producing cushion packaging from rice husk and coconut fibre while reducing the amount of pulping material required from virgin wood and the usage of petroleum for making Polystyrene. This study aims to design cushion packaging from rice husk and coconut fibre using the lean concept while studying the compatibility of these cushions as primary packaging. The cushion is designed using AutoCAD software. Three types of cushion packaging models are created using different compositions of rice husk (RH) and coconut fibre (CF): Model 1 (100% RH 0% CF), Model 2 (50% RH 50% CF), and Model 3 (0% RH 100% CF). Each composition is combined with 450g of latex adhesive and 50g of water. The impact performances of cushions from different compositions are conducted using the Drop Tester Model AD-100 Design Series 4410 based on the Standard ASTM D 5276 (Drop Test of Loaded Containers by Free Fall 1998). Model 2 (50% RH 50% CF) gave the best performance in the capability to withstand the impact at a fixed height of 92 cm in the drop test compared to Model 1 (100% RH 0% CF) and Model 3 (0% RH 100% CF). Thus, the composition of rice husk and coconut fibre is the most suitable as packaging cushioning compared to the cushion with a single composition of rice husk or coconut fibre.
