Abstract

The aims of this study is to determine the ballistic properties of densified, reinforced, and laminated wood material. For this purpose, the samples obtained from Uludağ Fir (Abies nordmanniana subsp. bornmülleriana mattf.) and black poplar (Populus nigra L.) woods were impregnated with melamine formaldehyde resin and then densified at 120 °C and 140 °C with 25 % and 50 % thermo-mechanical method, and the panels were prepared. Then, these panels were laminated using 3, 5, and 7 layers, fiberglass, and carbon fiber reinforcement materials. Ballistics tests were carried out following the NIJ 01010.06 standard. In addition, stereo microscope and SEM images were examined to determine the changes in the anatomical structure of the wood material after the densification treatment and the adhesion of the melamine formaldehyde and polyurethane resins to the wood material. As a result of the ballistic test, laminated materials did not provide protection. Afterward, 2 pieces of 5 and 1 piece of 3-layer laminated panels were produced for ballistics tests. Ballistic protection was obtained from fiberglass and carbon fiber reinforced, laminated materials obtained from Black poplar and Uludağ Fir wood materials, which are 50 % densified at 120 °C and 140 °C. It is recommended that the panels be reinforced with fiberglass and carbon fiber, and 50 % densified panels can be used indoors and outdoors where ballistic resistance is required.

期刊介绍： Engineering Science and Technology, an International Journal (JESTECH) (formerly Technology), a peer-reviewed quarterly engineering journal, publishes both theoretical and experimental high quality papers of permanent interest, not previously published in journals, in the field of engineering and applied science which aims to promote the theory and practice of technology and engineering. In addition to peer-reviewed original research papers, the Editorial Board welcomes original research reports, state-of-the-art reviews and communications in the broadly defined field of engineering science and technology. The scope of JESTECH includes a wide spectrum of subjects including: -Electrical/Electronics and Computer Engineering (Biomedical Engineering and Instrumentation; Coding, Cryptography, and Information Protection; Communications, Networks, Mobile Computing and Distributed Systems; Compilers and Operating Systems; Computer Architecture, Parallel Processing, and Dependability; Computer Vision and Robotics; Control Theory; Electromagnetic Waves, Microwave Techniques and Antennas; Embedded Systems; Integrated Circuits, VLSI Design, Testing, and CAD; Microelectromechanical Systems; Microelectronics, and Electronic Devices and Circuits; Power, Energy and Energy Conversion Systems; Signal, Image, and Speech Processing) -Mechanical and Civil Engineering (Automotive Technologies; Biomechanics; Construction Materials; Design and Manufacturing; Dynamics and Control; Energy Generation, Utilization, Conversion, and Storage; Fluid Mechanics and Hydraulics; Heat and Mass Transfer; Micro-Nano Sciences; Renewable and Sustainable Energy Technologies; Robotics and Mechatronics; Solid Mechanics and Structure; Thermal Sciences) -Metallurgical and Materials Engineering (Advanced Materials Science; Biomaterials; Ceramic and Inorgnanic Materials; Electronic-Magnetic Materials; Energy and Environment; Materials Characterizastion; Metallurgy; Polymers and Nanocomposites)
