automotive and aerospace industries are required to light materials which have high properties. this causes to reduce production cost and fuel consumption. one of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. these materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. powder metal...

in this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (cnts) is proposed in detail. the negative coefficient of thermal expansion and the high young’s modulus of cnts can be utilized to counterbalance the process induced residual stresses in composites. to this end, first, the effects of adding cnts to the matrix of fibrous composi...

Metal–polymer composites were investigated for their microwave properties in the frequency range of 30–1000 MHz to assess their application as inductor cores and electromagnetic isolation shield structures. NiFe and Fe nanoparticles were dispersed in epoxy as nanocomposites, in different volume fractions. The permittivity, permeability, and loss tangents of the composites were measured with an ...

Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditio...

Lightweight design, using high performance composites, which directly yields a reduced need for fuel is in the focus of new developments for traffic engineering. The increased substitution of traditional, metal based materials by fibre-reinforced composites in the aviation industry exemplifies this trend. In addition to mechanical properties, e.g. an increase in strength, that leads to direct w...

Abstract The characteristics and structural performance of a composite material’s properties are better than those its component parts because It comprised pair or more insoluble, chemically separate stages. functioning alone. ‘Metal-Matrix’ composites materials that have been produced from metals ceramics had fibers particles incorporated into them to enhance their physical characteristics. fa...
