    Due to the growing environmental concern, lignocellulosic materials have become a common substitute for the conventional reinforcement element in composite strcutures. However, these natural sources are preferred to cost efficient and to increase mechanical performances. In a cement bonded composites, wood is incorporated as an aggregate in the mineral matrix (as fibres, sawdust, shavings or particles), and cement acts as a binder. These are employed due to their ease of production, and the enhanced biodegradability, leading to applications for sustainable purposes in construction applications. Wood-cement composites are considerably better performance on high fire, weathering and bio-deterioration risk applications to which solid wood and resin bonded composites are vulnerable. However, the vast of literature on cement-wood bonded composites has already been reviewed and pointed by a number of researchers. Many valuable fundamental informations have already established for utilizing wood for these products. A comprehensive results was to investigate some wood species that are abundant resources in many countries, for their suitability for manufacturing such composites.

    Electromagnetic Interference Shielding Effectiveness of Copper Foil Coated Oriented Strand Board
    (Burdur Mehmet Akif Ersoy Üniversitesi, 2018) Kaya, Ali İhsan; Çifci, Ahmet
    The influence of growth of electronics industry and its widespread use in communications, automation, biomedical, space and other fields leads to many electromagnetic interference problems. Electromagnetic interference is the deterioration of operation of an electronic device when it is in the close neighborhood of an electromagnetic field in the radio frequency spectrum that is caused by another electronic device. This deterioration affects electronic devices as well as human health. Therefore, there is a need to effectively protect against the adverse effects of electromagnetic interference. In this paper, copper board and oriented strand board were used as a hybrid composite material. The interface and surface of oriented strand board were coated with copper foil and the metal cage was formed. It was found that electromagnetic shielding effectiveness in the frequency range of 1.88 GHz - 2.62 GHz and 5.20 GHz - 5.62 GHz of the oriented copper foil coated oriented particle board was acceptable.
