Metal Matrix Composites (MMC's) have evoked a keen interest in recent times for potential applications. Advance composite materials like Al/SiC metal matrix composite is gradually becoming very important materials in manufacturing industries e.g. aerospace, automotive and automobile industries due to their superior properties such as light weight, low density, high strength to weight ratio, high hardness, high temperature and thermal shock resistance, superior wear and corrosive resistance, high specific modulus, high fatigue strength etc. In this study aluminum (Al-6063)/SiC Silicon carbide reinforced particles metal-matrix composites (MMCs) are fabricated by melt-stirring technique. The MMCs bars and circular plates are prepared with varying the reinforced particles by weight fraction ranging from 5%, 10%, 15%, and 20%. The average reinforced particles size of SiC are 220 mesh, 300 mesh, 400 mesh respectively. The stirring process was carried out at 200 rev/min rotating speed by graphite impeller for 15 min. The microstructure and mechanical properties like Proportionality (MPa) limit, Tensile strength upper yield point (MPa), Tensile strength lower yield point (MPa), Ultimate tensile strength (MPa), Breaking strength(MPa), % Elongation, % Reduction in area, Hardness (HRB), Density (gm/cc), Impact Strength (N.m) are investigated on prepared specimens of MMCs. It was observed that the hardness of the composite is increased with increasing of reinforced particle weight fraction. The tensile strength and impact strength both are increased with rising of reinforced weight fraction. Different mechanical tests were conducted and presented by varying the particle size and weight fractions of SiC.

“…For a MH with a gravimetric density of 5% this is 54.6 kg MH rounded up to 60 kg for casing, etc. According to the influence of total vehicle weight on fuel economy by Allison and Cole [34] an increase of the vehicle weight of 10% has a 5.5% lower fuel economy. 21 All emission factors are taken from the Concawe study [22].…”

Hydrogen onboard storage technologies form an important factor in the overall performance of hydrogen fuelled transportation, both energetically and economically. Particularly, advanced storage options such as metal hydrides and carbon nanotubes are often hinted favourable to conventional, liquid and pressurized, storage options. This study assesses the technical and economic performance of four onboard storage technologies in a well-to-wheel assessment. It does so for centralized and onsite hydrogen production scenarios with gaseous pipeline and liquid truck distributed hydrogen. Energetically, centralized production and liquefaction outperforms onsite production and liquefaction by 20% on the average primary energy input, despite the need of pipeline or over the road distribution. The gaseous handling on the filling station performs better with an average driving energy use of 0.11 MJ p /km compared to 0.15 MJ p /km for liquid handling. The advanced onboard storage technologies perform better by 22% than the conventional storage technologies on primary energy input in the chain. The average driving cost for gaseous and liquid onboard storage are 53% above the gasoline reference cost of 21 ¥ct/km and the advanced onboard storage technologies as much as 98%, almost double the reference cost. The car expenditure for a fuel cell driven car compared to an internal combustion engine driven car is for a large part responsible for this difference. Advanced onboard storage technologies thus perform better than conventional onboard storage technologies energetically albeit to higher cost. ᭧
