In this study, compressive strength and contraction of Polymer Composite Laminates made of E-Glass / Carbon bi-woven fabric reinforced in Epoxy resin matrix has been evaluated experimentally. Composite laminates were fabricated using hand lay-up technique for different ply orientations of 0,30,45,60 and stacking sequence of (00/300/450/600)2S for 2 and 3 mm laminate thickness. The laminates wer...

A composite material is a combination of two or more materials arranged in the form of layer one on the other layer using binding material through some prescribed methods. In the Glass fibre coconut fibre human hair hybrid composite method, the epoxy resin is used as binding material, in which one layer is formed of glass fibre, followed by coconut fibre and then by human hair. By using hand la...

fiber metal laminates are hybrid laminates consisting of thin alternating bonded layers of aluminum and fiber/epoxy. arall (aramid aluminum laminate) and galare (glass fiber reinforced aluminum laminate) are specific kinds of fiber metal laminates that consist of thin aluminum sheets along with kevlar/epoxy and glass/epoxy composite layers, respectively. in this study, nonlinear tensile behavio...

Abstract Firstly, three groups of fiber curve laminates with different numbers layers and angles were designed prepared. A cantilever plate free vibration test was used to analyze the influence angle on attenuation characteristics laminates. The contrast results show that has a significant effect loss factor laminate structure. When change ±<45|60>, reached maximum value, damping performa...

In this paper, a method of solution and some numerical resu~s of free vibration and buckling of composite laminates are presented. All the edges of the laminates are assumed as simply supported. Ritz's method of solution is used with deflection surface expressed in terms of double series in Chebyshev polynomials satisfying the simply supported laminate boundary conditions. The numerical results...

-This paper focus on investigating the impact property of laminated composites.The test are performed based onASTM standardsD3029 and D7137.The impact test were carried out using an instrumented drop weight test. The behavior of E-glass/epoxy and carbon fiber laminated composite plates has been experimentally studied under impact of steel projectile at low velocities. The results were obtained ...

Abstract. Variable stiffness composites present additional tailoring capabilities if compared to classical straight fiber composites. However, the fabrication of these advanced leads inevitably presence manufacturing signatures such as gaps and overlaps, which alter mechanical behavior laminated components. In this work, fundamental frequency variable laminates with overlaps is studied. The Def...

Microcracking in composite laminates is a known precursor to the growth of inter-ply delaminations and larger scale damage. Microcracking can lead to the attenuation of ultrasonic waves due to the crack-induced scattering. 3D elastodynamic finite integration technique (EFIT) has been implemented to explore the scattering of ultrasonic waves due to microcracks in anisotropic composite laminates....

The problem of determining exact expressions for the effective stiffness tensor macroscopically anisotropic, two-phase composite media of arbitrary microstructure in arbitrary space dimension d is considered. We depart from previous treatments by introducing an integral equation for the “cavity” strain field. This leads to new, exact series expansions for the effective stiffness tensor of macro...
