Epoxy was reinforced with aluminium particles of different sizes. Bond, functional group and chemical formulae of the composite phases were examined using Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffractometer. The flexural test was also conducted on the developed composites via three-point method. Analysis of variance (ANOVA) was performed using aluminium percentage by weight (wt%) and sizes (Ps) as the predictor variables. Results indicated different chemical formulae of the composite phases. A maximum of 124.44 % increase in flexural modulus was found at 12 wt% reinforcement addition. Probability value, 0.000 for each of wt% and Ps affirm evenly significant influence of both variables on flexural modulus of the composites. Hence, the developed multiple regression model can be used for predicting the flexural modulus of epoxy particulate composites within and outside the scope of experiment.

- ItemStudy of tensile properties, fractography and morphology of aluminium (1xxx)/coconut shell micro particle composites(Elsevier/Springer, 2017) Bello Sefiu Adekunle; Raheem Isiaka Ayobi; Raji Nasirudeen KolawoleAluminium (1xxx)/coconut shell micro particle (Al/CMP) composites have been developed using a compo cast technique. Coconut shells (CSs) were processed with the aid of mortar/pestle and disc grinder and then classified with a set of sieves vibrated with a sine shaker. The CMP additions increased from 2% to 10% at 2% interval. Microstructural/chemical composition analyses were carried out with the aid of scanning electron microscopes (ASPEX 3020) with attached energy dispersive X-ray spectroscopy. Phases were identified using an X-ray diffractometer (XRD). The tensile properties and mode of fracture were studied using Instron extensometer and Avery Denison Impact Testing Machine respectively. Results revealed 99.3% purity of aluminium matrix. The presence of new phases in the aluminium matrix is attributable to chemical interaction between Al and CMPs. The fine grained structure of Al/CMPs composites was confirmed by SEM and optical micrographs. The enhancement in the tensile properties is attributable to the presence of hard phases in the Al matrix and good interfacing bonding between Al matrix and CMP reinforcements. The cone and cup surface appearance with fibrous, dull, dimple and goose grain microstructure of the fracture surfaces of the composites is an indication of ductile fracture. Hence low cost metal matrix aluminium based composites have been developed.

- ItemVehicle bumper fascia prototyping using sustainable nanocomposites(Elsevier, 2025-04-23) Bello Sefiu Adekunle; Olaitan Sodiq Olamide; Adebayo Mohammed Kayode; Akinwande Lateef Olayinka; Olaitan Funsho Kolawole; Kolawole Maruf Yinka; Suberu Abdulmumuni Ariboh; Arowoduye Fawaz Afolami; Akangbe Muhiz; Michael Roseline Ifeoluwa; Adeyi TimothyEggshells and date seeds are wastes which contribute to land pollution. Their conversions to useful materials are important to save the environment from the health hazards associated with rotten eggshells and possible impacts from the date seed wastes. This study focuses on conversion of eggshells and date seeds into reinforcing particles for producing sustainable polymeric and metallic nanocomposites for prototyping a vehicle bumper fascia. Eggshell nanoparticles were incorporated into low-density polyethylene up to 12 wt%. Metallic nanocomposites were produced using Al–Cu–Mg sourced from aluminium alloy scraps and date seed particles and then, heat treated. The developed nanocomposites were analysed chemically, structurally, and mechanically. The structural integrity of the polymeric nanocomposites was confirmed by the scanning electron microscope. Enhancements in impact energy, tensile and flexural strengths at 12 wt% of eggshell nanoparticle additions to the very low-density polyethylene are 1.5, 110.4 and 47.7 %, respectively. 1 wt% date seed particle reinforced Al–Cu–Mg that has highest impact energy after annealing treatment is selected for the mould parts fabrication for forming the bumper fascia. Property comparison of the produced polymeric nanocomposites with those of existing bumper fascia materials affirms that the tensile strength and impact energy of the nanocomposite that contains 12 wt% eggshell nanoparticles are suitable for the automobile bumper fascia. Hence, fabrication of the bumper fascia using the VLDPE/12 wt% eggshell nanocomposite was fruitful.
