The study of the microstructure and interfacial reaction of Al–Cu–Mg/bagasse ash particulate composite

“…Silica is reported to be one of the hardest materials as reported by Hassan and Aigbodion [7] and Alaneme et al [1]. However, the low hardness exhibited by the sample with 0 wt.% SP addition can be attributed to the monolithic and relatively soft carbon matrix.…”

Materials selection and development for application in advanced systems is becoming highly complex involving the need for lower cost alternatives without compromising service performance. This paper investigated selected critical mechanical properties of ceramic matrix composites synthesized from coconut shell carbon (CSC) reinforced with silica particles (SP). Coconut shells (CCS) and silica sand (SS) were pulverized separately in a plate mill and a ball mill respectively to obtain a particle size of 250 μm. The CCS powders were calcined at 5000 C in an oven to obtain coconut shell ash (CSA) which was carbonized in a furnace from 5000 C-10000 C under argon gas controlled environment. The materials were mechanically blended while the SP additions varied from 10-40 wt. % and compacted using hydraulic press. The compacted mixture was sintered at 5000 C-12000 C, held for 2 hrs and the composites characterised for mechanical properties while the microstructural integrity was analysed using scanning electron microscope/energy dispersive x-ray spectroscopy (SEM/EDS). Microstructure showed that after sintering, coconut shell carbon developed strong cohesion with the silica particles which gave rise to effective load transfer. The mechanical properties that ensued demonstrated on the average 52.8 % comparability with conventional power plant structural materials in terms of hardness, compressive strength and impact energy.

This study provides a bibliographic review for future reference in the broad field of bagasse composites by looking for factors that influence their attributes. As an abundant agriculture resource, sugarcane bagasse has attracted extensive research interests because of its high annual yields, low costs, and environmental-friendly characters. During these research, various parameters have been tested to identify their effects; however, these studies are carried out dispersedly. This review provides a summary of these factors, their impacts, and mechanisms. Three factors are used to explain the attributes of bagasse composites followed by the factors involved in preparation, modification, and additives and also their influences. Then the best mechanical properties of different bagasse composites and their achieving condition are summarized. Durability is also reviewed. Additionally, competitive application of bagasse composites is defined by comparing their attributes with other natural fiber composites.
