To understand the effect of a 'mesh-structured reinforcement' on the optical and mechanical properties of optomechanical composites, a unidirectional Al2O3 fibre-ZrO2 matrix minicomposite reinforced glass matrix optomechanical composite has been fabricated. By regular alignment of the minicomposites in the glass matrix as part of the 'mesh structure' a high degree of optical transparency is obtained in the composite; this transparency is proportional to its 'optical window' regions. The mesh structured reinforcement composed of millimetre order widely spaced minicomposites is effective in improving the fracture resistance of the resulting composites primarily through an intact minicomposite bridging mechanism. Use of the minicomposite type of reinforcement is one possible means of improving the mechanical properties of brittle matrix optomechanical composites.

Improvement of fracture resistance in a glass matrix optomechanical composite by minicomposite unit bridging Dericioğlu, Arcan Fehmi (Elsevier BV, 2005-10-15) Minicomposite unit bridging, which was experimentally determined to be the dominant toughening mechanism resulting in the R-curve behavior of the Al2O3-ZrO2 minicomposite-reinforced glass matrix optomechanical composite, was studied quantitatively using luminescence spectroscopy. Applied stress induced shift of the luminescence bands of the minicomposite reinforcement was calibrated. Using the experimentally obtained calibration curve, axial stresses could be mapped along the minicomposite embedded in the g...
Structural, electrical and anisotropic properties of Tl4Se3S chain crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2009-10-01) The structure, the anisotropy effect on the current transport mechanism and the space charge limited current in Tl4Se3S chain crystals have been studied by means of X-ray diffraction, electrical conductivity measurements along and perpendicular to the crystal's c-axis and the current voltage characteristics. The temperature-dependent electrical conductivity analysis in the region of 150-400 K, revealed the domination of the thermionic emission of charge carriers over the chain boundaries above 210 and 270 K...
Surfactant-modified multiscale composites for improved tensile fatigue and impact damage sensing Yesil, Sertan; Winkelrnann, Charles; Bayram, Göknur; La Saponara, Valeria (Elsevier BV, 2010-10-25) This paper documents the mechanical and electrical performance of self-sensing conductive polymer composites prepared with a low-cost technique and small hardware, able to considerably improve the dispersion and the surface adhesion of multi-walled carbon nanotubes (CNTs) in epoxy resin with respect to amine-modified CNTs and as-received CNTs. Surface treatment of the CNTs is performed using hexamethylene diamine, or a mix of sulfuric and nitric acid, and one of two surfactants (for the diamine treatment on...
Investigation of the variations in microstructure and mechanical properties of dual-matrix ductile iron by Magnetic Barkhausen Noise analysis Gür, Cemil Hakan; Erdogan, Mehmet (Informa UK Limited, 2008-01-01) The variations in the microstructure and tensile properties of dual-matrix ductile irons have been investigated non-destructively by Magnetic Barkhausen Noise (MBN) method. Specimens have been intercritically austenitised at 795 degrees C and 815 degrees C for 20 minutes, and then oil-quenched to obtain different martensite volume fractions. Two specimens, namely as-cast and oil-quenched from 900 degrees C, were prepared for comparison purpose. To investigate the effect of tempering, some specimens were tem...
Multi-scale characterization of particle clustering in discontinuously reinforced composites CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01) The applicability of a quantitative characterization scheme for cluster detection in particle reinforced composites is discussed. The method considers the pattern from the perspective of individual particles, so that even in a pattern that globally conforms to a random distribution, micro-scale heterogeneities can be detected. The detected clusters are visualized by kernel surfaces. Results indicate that the presented methodology is an effective discriminator of clusters and can successfully be used for qua...
