In an attempt to reduce the crack propagation speed in structures made of fiber-reinforced composites metal layers are added laminate forming a new group materials, so-called fiber laminates. GLARE, combination glass polymer and aluminum, is well-known frequently used aeronautical industry. One major drawback such materials their susceptibility impact damage, which not detectable by visual insp...

To maintain the continuous product flow in pipe, durability of pipe structure is achieved through insulation. The composite material will be used as main material, since it may have combined characteristics constituents or substantially different properties than individual constituents. Replacing damaged with a new one not only consume high cost but also create complication for flow. As to alle...

Composite material structures are commonly used in many industrial sectors (aerospace, automotive, transportation), and can operate in harsh environments where impacts with other parts or debris may cause critical safety and functionality issues. This work presents a method for improving the accuracy of impact position determination using acoustic source triangulation schemes based on the data ...

Three-dimensional transient deformations of a laminate comprised of several unidirectional fiber reinforced layers perfectly bonded to each other and subjected to a blast load are analyzed by the finite element method with an in-house developed, verified and fully validated code with rate-dependent damage evolution equations for anisotropic bodies. The continuum damage mechanics approach employ...

A leading reason for the limited use of laminated composite materials in primary structural applications is that failure initiates in the ply oriented transverse to the direction of the applied load at a much lower strain than that which would cause the ultimate failure of the laminate. Previous studies indicate that transverse failure is manifested as either cavitation induced brittle failure ...

A novel cation exchange fiber supported solid membrane was developed for transport of cobalt, manganese and nickel metal ions. Fiber supported solid membrane was prepared by chemically modifying the cellulose fibers with citric acid. In the fiber supported solid membrane, the diffusion by capillary action by keeping the liquid phase in the porous solid fiber and ion exchange mechanism were used...

Based on the HyperWorks software, this paper takes layup sequence of carbon fiber composite laminates as design variables, main strain and continuous angle not exceeding four layers constraints, maximum bearing capacity goal. The optimized laminate corresponding experimental verification were carried out. results are in good agreement with simulation analysis results, indicating that optimizati...

The aim of this work is to investigate analytical (Classical theory) and [ANSYS Parametric Design Language (APDL)] analysis laminate composite plate. free vibration with two boundary conditions simply supported (SSSS) & clamped ends (CCCC) are taken into account in work. equations motion that governs the predication dynamic behavior cross angle ply solved theoretically using [Matlab] softwa...

Uniform Fiber Bragg Grating sensors based on Polarization-Maintaining fibers are designed for simultaneous longitudinal strain and temperature measurement of Carbon Reinforced Polymer laminates. Panda, Bow tie Pseudo-rectangle optical fiber shape sections investigated employing three different embedding methods, each fiber. The simulation accurately takes into account that the embedded in unidi...
