Composite materials such as fiber metal laminates combine the advantages of metallic and fiber-reinforced polymers. Hence, these are great interest for thin-walled structures in lightweight engineering. Due to structure materials, damage laminate components occur more frequently inside than with conventional materials. Since detection interlaminar is complicated compared external damage, it one...

A comparison between the vibration of fiber-metal laminate (FML) and composite cylindrical shells has been studied in this manuscript. Love’s first approximation shell theory has been applied to obtain Strain-displacement relations. In addition, beam modal function model has been used to analyze the cylindrical shell with different boundary conditions. In this manuscript, the frequencies of FML...

The bias-extension test is one of the methods to characterise intra-ply shear behaviour continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For determination major mechanical properties metals, often a uniaxial tensile used. Combination these two for deformation hybrid metal-composite laminates proposed comparing method cross-plied prepregs woven fabric p...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

Electromagnetic shields are designed to optimize the performance for shielding effectiveness and reflectivity. Multilayered laminates of different materials are developed to achieve excellent results in terms of not only in shielding effectiveness but also for reflectivity. In this paper, a three layered laminate is considered for estimation of the required parameters in the X-band frequency ra...

Structural health monitoring of composite structures may be accomplished by measuring strains with embedded optical fibre sensors. In this paper, we present the performance of Bragg grating sensors, which are imbedded into a carbon composite laminate and them bonded to the structure in analyse. The paper will briefly discuss the results and compare them with a free fibre Bragg grating bonded in...

Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

background: mushroom tyrosinase a potent candidate in clinical studies known as polyphenol oxidase, is a metaloenzyme from the oxidase superfamily widely distributed from lower to higher life forms. it plays a crucial role in sclerotization of exoskeleton in insects, also responsible for skin pigmentation in mammalians. objective: in this study, after reconstitution of mt by some metal ions, th...
