Remanufacturing is a powerful tool for developing ecological approach for many application Degrade honeycomb sheets for architectural use in construction are broadly used for ceiling, cladding and interiors applications End-of-life vehicle steel sections are used as cores to produce honeycomb steel where there are only three sections can be used such sections are attributed in the final products liability and quality. Remanufacturing of steel sections Remanufacturing of end of life steel vehicles sections in to honeycomb cores is targeting to reduce power ,material and fossil carbon emissions of end of life steel vehicles frame is studied and disassembled to classify the suitable parts for Remanufacturing the cores for steel honeycomb steel also thin steel sheets are used to covers. Remanufacturing and testing routes are figured and .Mechanical properties are tested and registered to be used for performance study end of life vehicle sections can be successfully degraded in to honeycomb cores to substitute current consumption of materials. Mechanical properties can be developed to match construction application standards by exploiting of sustainable assembling technology by using screens .As a conclusion reliable steel honeycomb can be matured by exploiting in remanufacturing technology and assembly techniques end -of-life sections can contribute to reduce power, materials consumption and carbon emissions.KEY WORDS: vehicle end-of-life steel remanufacturing, honeycomb cores, ecological approach. 192Rawa 'a H.

In this paper, laminated composite materials were hybridized with fibers (E-glass) and shape memory alloy wires which considered a smart material. The effect of changing frequency on the (acceleration- frequency) response curve, the damping ratio of the vibration modes, the natural frequencies of the vibration mode, the effect of shape memory alloy wires number on the damping characteristics were studied. Hand lay-up technique was used to prepare the specimens, epoxy resin type was used as a matrix reinforced by fiber, E-glass. The specimens were manufactured by stacking 2 layers of fibers. Shape memory alloy, type Nitinol (nickel-titanium) having a diameter (1 and 2mm), was used to manufacture the specimens by embedding (1,2 and 3) wires into epoxy. Experimentally, the acceleration- frequency response curve was plotted for the vibration modes, this curve was used to measure the natural frequencies of the vibration modes and calculate the damping ratio of the vibration modes. ANSYS 15- APDL was used to determine the mode shape and find the natural frequencies of the vibration modes then compared with the experimental results. The results illustrated that, for all specimens increasing the natural frequency leads to decreasing the damping ratio. Increasing the number of shape memory alloy wires leads to increase the values of the damping ratio of the vibration modes and the natural frequencies of the vibration modes at room temperature.
