B4C–Al2O3 composite powder was produced by aluminothermic reduction in Al/B2O3/C system. In this research, microwave heating technique was used to synthesize desired composite. The ball milling of powder mixtures was performed in order to study the effect of mechanical activation on the synthesis process. The synthesis mechanism in this system was investigated by examining the correspondi...

In this paper a composite plate with similar unidirectional fibers is considered. Assuming orthotropic structure, theory of elasticity is used for investigating the stress concentration. Also, complex variable functions are utilized for solving the plane stress problems. Then the effective characteristics of this plate are studied numerically by using ANSYS software. In this research a volume e...

A novel self-cleaning polymer composite with self-healing ability to self-repair after chemical and mechanical damage using readily available materials like polydimethylsiloxane (PDMS) and camphor soot particles is developed. With the optimal loading of the camphor soot particles, the composite coating on glass and stainless steel surfaces reveals self-cleaning properties with a water contact a...

th dentistry. Early 20 century sawintroduction of various newer materials like stainless steel, cobalt chromium alloys, acrylic resins(heat cure and self-cure) as DB materials.However, acrylic resin seems to be a material, which got more attention because it fulfils many of the desired properties like ease of processing, favourable working characteristics, accurate fit, stability in oral enviro...

An important parameter in composite materials is mechanical behavior and matrix-reinforcement interface interaction under applied stresses. In this investigation, bending strength of carbon-carbon composites synthesized from wood was analyzed as a measure of the composite mechanical properties. Also, densification efficiency of the products was determined by measuring the bulk density and open ...

Glass fibre reinforced plastic (GFRP) is considered as structure support and insulating material for the new superconducting FAIR magnets. GFRP (G11) is a composite material consisting of woven glass fibres (volume fraction ~50 %) and cured polymer resin (e.g. amine-cured epoxy). The material will be exposed to cryogenic temperatures, high radiation levels and dynamic mechanical loads (Lorentzi...
