Solid-state recycling, which involves the direct recycling of scrap metal into bulk material using severe plastic deformation, has emerged as a potential alternative to the conventional remelting and recycling techniques. Hot press forging has been identified as a sustainable direct recycling technique that has fewer steps and maintains excellent material performance. An experimental investigat...
composite pressure vessel cng made of epoxy – carbon material with nonmetal liner is 60% lighter than aluminum vessel under the same conditions. one of the important parameters in the pressure vessels design is their resistance against impact and prevention of explosion. in this paper, the effects of low velocity impact on composite pressure vessel are investigated using fe analysis. the vessel...
Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. A composite mixture having more than one fiber is known as hybrid composite During the past decade, considerable research effort has been directed towards the development of in situ Metal Matrices h...
fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...
1 General Introduction Recently, transmitting greater amounts of electric energy has become a global issue that has arisen due to the fact that current transmission line designs (based upon steel cores) are thermally limited, which restricts the amount of power that can be delivered. Utilities are faced with the difficult task of increasing power delivery under severe constraints [1]. To solve ...
INTRODUCTION JET-Fresh (Dentsply International, York, PA), a new airpolishing powder that contains aluminum trihydroxide as the abrasive agent, has been introduced for use with Prophy-Jet trade mark (Dentsply International). PURPOSE The aim of this study was to investigate the surface effects of aluminum trihydroxide airpolishing powder on a series of restorative materials. MATERIALS AND ME...
friction stir processing was applied for fabricating an aluminum alloy based hybrid nano composite reinforced with nano sized al2o3 and micro sized graphite particles. a mixture of al2o3 and graphite particles was packed into a groove with 1 mm width and 4.5 mm depth, which had been cut in 5083 aluminum plate of 10 mm thick. packed groove was subjected to friction stir processing in order to im...
In the present paper, the problem of low velocity impact of plates made from different configurations of ceramic, aluminum, steel and composite (S-glass polyester) is analyzed numerically using Abaqus finite element software. The projectile is assumed to be a rigid body with a hemispherical head. Also, for ceramic layers, Holmquist constitutive model, for aluminum and steel layers, Johnson Coo...
A repeated thermomechanical treatment (RTMT) was adopted to control the microstructure of a glass-balloon-dispersed aluminum alloy (AC3A) composite. The RTMT, which involves the repetition of a multi-step process and followed by heat treatment, was applied to a cast plate of the composite. The composite was successfully worked into a rod or sheet by either swaging or flat rolling. The porous gl...
