“…Metal Matrix Composites (MMCs) are an engineered combination of metal (matrix) and hard particles (reinforcement) to produce properties of a desired specification [10][11][12][13]. Due to the rapid industrial and technological growth, given the opportunities for various applications, economic and environmental benefits, it is becoming increasingly important to develop material that will have a good strength-toweight ratio suitable for automotive, aerospace and defence applications from industrial, agro and bio-waste resources [14].…”

Snail shells (SnS), which represent the discarded bio-shell waste of snails' remnants from restaurants and eateries constitute a serious degree of environmental threat with little or economic value. The effective utilisation of this waste into a green metal matrix composite as a low cost reinforcement material applicable in the automotive industry in lieu of its present hazardous impact had stimulated the research interest. Hence, this paper studies the potential utilisation of SnS as a low cost reinforcement material in the metal matrix composites (MMCs) by means of a characterisation technique. The mineralogical composition and physical properties of the snail shell powder was carried out using the density determination, thermogravimetric analysis (TGA), refractoriness, energy dispersive X-ray (SEM/EDX), X-ray fluorescent (XRF) and the X-ray diffraction (XRD) analysis at 0, 800, 850 and 900 C. The TGA result shows that the SnS attained its thermal stability at 840 o C. The above results imply that SnS with (9.4-25.9) % lesser density when compared with agro or industrial wastes reinforcement material (flyash, coconut shell ash, maize husk, bagasse) in the metal matrix composite looks promising as a reinforcing material in the production of light weight metal matrix composites at low costs. Also, the high refractoriness temperature of the snail shell particle suggested it as a suitable candidate reinforcement material in the production of thermal resistance MMCs applicable in automotive components such as pistons and connecting rods.

“…The mechanical and tribological properties of the CrN coating deposited under different ratios of sputtering gas and reactive gases are reported in the literature [19][20][21][22][23]. Olaya et al [24] noted that the RF bias voltage influenced the crystal orientation and hardness of the deposits.…”

Chromium Nitride (CrN) thin films are known for their comparatively good mechanical properties. CrN was deposited on Silicon (100) and glass substrates by using DC magnetron sputtering and the influence of the partial nitrogen content and different gaseous environment on their microstructural characteristics were investigated in the present work. The CrN films were characterised with X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Atomic Force Microscopy (AFM) and Nanoindentation was used to characterise the structural and mechanical properties of the deposited thin film. The films showed the [200] preferred orientation at lower (at 20%) nitrogen contents while the intensity of the peak [111] increases with the increase in the nitrogen content. The Cr2N (220) peak was identified at a nitrogen content above 30%, but for nitrogen content above 40%, the CrN phase was observed in both films deposited on Si(100) and glass substrates. The preferred orientations of the CrN thin films are strongly influenced by the nitrogen content inside the chamber as observed in the present work. The surface roughness and deposition rate were observed in a reducing trend with the increasing N2 content and temperature from 20.31 to 2.71nm and from 30.16 nm/min to 25.66nm/min, respectively. The hardness and modulus of pure N2 films deposited on the Si substrates were evaluated by nanoindentaion testing and indicated 31 GPa and 250 GPa, respectively.

“…The choice of constituent materials depends mainly on the specific application and design criteria of the sandwich panel products [1]. The most outstanding benefit of this type of composite structure is its high strength and stiffness to weight ratio [2][3][4][5][6][7][8]. On the other hand, this typical structure also has a few drawbacks; they suffer from strong stress concentration at the interfaces between the face sheets, the weak adhesive layer, and the core, as a consequence of the distinctly different properties of these materials in contact [9].…”

Polymeric composites reinforced with natural fibers have raised more attention as the alternative building materials. In this work, natural fiber composites prepared from jute and hemp fiber were proposed for the intermediate layer of a hybrid sandwich panel. This paper presented the flexural behavior of the newly developed hybrid sandwich panel which included the comparison of the ultimate load, load-deflection behavior, load-strain behavior and failure modes. The study was designed as a single factor experiment where the performance of hybrid sandwich panels containing jute fiber composite (JFC) and hemp fiber composite (HFC) as the intermediate layer was compared to the control (CTR) which was a conventional sandwich panel without an intermediate layer. A static flexural test under a four-point bending load scheme was performed in accordance with the ASTM C 393-00 standard. Aluminium sheet was used as the skins, while expanded polystyrene (EPS) was employed for the core. The testing was performed using a 100 kN servohydraulic machine with a loading rate of 5 mm/min. The applied load, displacement and strains were obtained using data logger. The results demonstrated that the hybrid sandwich panel exhibited a more superior performance than the conventional sandwich panels. The intermediate layer contributed significantly to enhancing the load carrying capacity of the hybrid sandwich panel. The load carrying capacity of hybrid panel with the JFC intermediate layer was 29.60% higher than the conventional sandwich panel, and correspondingly 93.46% higher for the sandwich panel with the HFC intermediate layer.The hybrid sandwich panels also developed a much larger area under the load-deflection curve, indicating greater toughness. The introduction of intermediate layer helped the hybrid sandwich panels to sustain a larger strain prior to reach their ultimate loads, resulting in a higher deformation capability. Indentation and core shear were observed as the failure mode of the conventional sandwich panel. Meanwhile, core shear and delamination were identified as the failure mode of the hybrid sandwich panel.
