The effect of bar sealing parameters on the heat seal strength of oriented polypropylene (OPP)/metallic cast polypropylene (MCPP) laminate film was investigated. Based on the results obtained from the parametric study, a bar sealing process window was developed. All points drop within the process window are combinations of platen temperature and dwell time that produce acceptable heat seal. Opt...

Porcelain laminate veneers have been a common treatment strategy in dental clinics. It is a conservative method for treatment of esthetic and functional problems in anterior region of oral cavity. Wide range of dental ceramics is now available on market for fabrication of laminate veneers. Clinician should have enough knowledge regarding the composition and properties of these materials in orde...

School children often encounter traumatic injuries like a crown fracture. They create serious functional, esthetic and psychological problems. Achievement of promising restoration that preserves its aesthetics and strength is the greatest desire for both children and their parents and is a challenging task for the dentist. The restorative options in these cases usually include composite resin a...

Anisotropy caused by flow-induced fiber orientation of discontinuous fibers within the extrudate in Extrusion Deposition Additive Manufacturing (EDAM) process gives rise to anisotropic shrinkage printed parts and thereby, final part deformations. Three states, described second-order tensor, were investigated determine their influence upon geometry. Two material systems including a short glass f...

Title of Dissertation: AN ANALYTICAL AND EXPERIMENTAL INVESTIGATION OF FILAMENT FORMATION IN GLASS/EPOXY COMPOSITES. Keith Leslie Rogers, Doctor of Philosophy, 2005 Dissertation Directed By: Professor, Michael Pecht, Department of Mechanical Engineering The drive to increase circuit density with smaller PWB geometries and higher layer counts in multi-layer boards along with the increasing use o...

Abstract Interlayer hybrid composites can be tailored for enhanced strength and stiffness. Research on enhancing the mechanical properties of is being explored by varying fiber orientations, layup sequence, different type materials. The objective this work to investigate effect stacking sequence high modulus carbon fibers tensile modal symmetric glass/carbon interlayer composite. were fabricate...

Uniform Fiber Bragg Grating sensors based on Polarization-Maintaining fibers are designed for simultaneous longitudinal strain and temperature measurement of Carbon Reinforced Polymer laminates. Panda, Bow tie Pseudo-rectangle optical fiber shape sections investigated employing three different embedding methods, each fiber. The simulation accurately takes into account that the embedded in unidi...

In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu(2+) ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N-O groups of two N-nitroso-N-pentyl-hydroxy-laminate ligands [Cu-O = 1.9042 (17) and 1.9095 (16) Å]. The hy-droxy-laminate monoanions are bidentate chelating ligands. The Cu(2+) cations form stacks alo...
