Optomechanical composites based on the system sapphire fibre/borosilicate glass matrix were fabricated and characterised. Different techniques of fabrication were used: composites with randomly orientated chopped sapphire fibres were produced by powder technology and pressureless sintering, whilst unidirectionally oriented fibre composites were fabricated by hot-pressing as well as by sandwiching glass slides and arrays of parallel fibres followed by heat-treatment. Pressureless sintered samples were poorly densified and were opaque. Hot-pressed and "sandwich structure" composites were dense and exhibited strong interfaces between fibres and matrix. Only the "sandwich structure" composites were transparent and showed significant light transmittance in the visible wavelength range, only 20% lower than that of the unreinforced matrix. Due to the strong matrix/fibre interface limited fibre pull-out during composite fracture was observed. The fabricated transparent composites represent an improved version of the traditional material wired glass. They are candidate materials for applications in high performance fire and impact resistant windows requiring high impact strength and avoidance of fragmentation upon fracture.

Control of the thickness distribution of evaporated functional electroceramic NTC thermistor thin films
Schmidt, R.; Parlak, Mehmet; Brinkman, Am (Elsevier BV, 2008-04-01)
In this work the thickness distribution of NTC thermistor thin films produced by low deposition rate (0.8 nm s(-1)) electron-beam evaporation is investigated. The target preparation, deposition conditions and geometrical set-up of the evaporation mechanism are described in detail. The evaporation geometry is shown to be critical for the thickness distribution of evaporated films. The film thickness distribution of evaporated layers was measured across a macroscopic film surface using Alpha Step stylus profi...
Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution
CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01)
The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTSK) model was used to simulate the solidification kinetics of the PMMCs. The experimental validation of the numerical model was achieved through the Newtonian and Fourier thermal analysis methods. Results reveal that the MTSK model can be successfully used ...
Sheet metal forming analyses with an emphasis on the springback deformation
FIRAT, MEHMET; Kaftanoglu, Bilgin; Eser, Orhan (Elsevier BV, 2008-01-21)
An accurate modeling of the sheet metal deformations including the springback is one of the key factors in the efficient utilization of FE process simulation in the industrial setting. In this paper, a rate-independent anisotropic plasticity model accounting the Bauschinger effect is presented and applied in the FE forming and springback analyses. The proposed model uses the Hill's quadratic yield function in the description of the anisotropic yield loci of planar and transversely anisotropic sheets. The ma...
Thermal and mechanical properties of Cu-Au intermetallic alloys
Kart, HH; Tomak, Mehmet; Cagin, T (IOP Publishing, 2005-07-01)
The thermal and mechanical properties of Cu, Au pure metals and their ordered intermetallic alloys of Cu3Au(L1(2)), CuAu(L1(0)) and CuAu3(L1(2)) are studied by using the molecular dynamics simulation. The effects of temperature and concentration on the physical properties of CuxAu1-x, are analysed. Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) many-body potentials are used. The simulation results such as cohesive energy, density, elastic constants, bulk modulus, heat capacity, thermal expansion, melting p...
Processing and characterization of carbon fiber reinforced silicon carbide (c/c-sic) matrix composites
Tülbez, Simge; Dericioğlu, Arcan Fehmi; Esen, Ziya; Department of Metallurgical and Materials Engineering (2015)
The current study was undertaken to investigate the production and characterization of Carbon Fiber Reinforced Silicon Carbide (C/C-SiC) Matrix Composites. Liquid silicon infiltration (LSI) method was utilized to produce the C/C-SiC composites. Processing of these composites via LSI process composed of three main stages. CFRP production, pyrolysis and liquid silicon infiltration. Each production stage has an important effect on the efficiency of the LSI process, therefore present study investigates the effe...
