The aim of this study is to investigate and compare the properties of two layer carbon epoxy composite plates manufactured using various resin impregnation techniques; Resin Transfer Molding (RTM), Light RTM (LRTM), Vacuum Assisted RTM (VARTM) and Vacuum Packaging (VP). Throughout the study a different packaging method was developed and named Modified Vacuum Packaging (BP). The mechanical properties of composite plates manufactured are examined by tensile tests, compressive tests, in-plane shear tests and their thermal properties are examined by Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA) tests. All tests were performed according to suitable ASTM standards. The performance of specimens from each process was observed to vary according to the investigated property; however the VP process showed the highest performance for most properties. For most of the tests, VARTM, LRTM and RTM methods were following VP process in terms of performance, having close results with each other.

Transient dynamic response of viscoelastic cylinders enclosed in filament wound cylindrical composites Şen, Özge; Turhan, Doğan; Department of Engineering Sciences (2005) In this study, transient dynamic response of viscoelastic cylinders enclosed in filament wound cylindrical composites is investigated. Thermal effects, in addition to mechanical effects, are taken into consideration. A generalized thermoelasticity theory which incorporates the temperature rate among the constitutive variables and is referred to as temperature-rate dependent thermoelasticity theory is employed. This theory predicts finite heat propagation speeds. The body considered in this thesis consists o...
Mixed-mode fracture analysis of orthotropic functionally graded materials Sarıkaya, Duygu; Dağ, Serkan; Department of Mechanical Engineering (2005) Functionally graded materials processed by the thermal spray techniques such as electron beam physical vapor deposition and plasma spray forming are known to have an orthotropic structure with reduced mechanical properties. Debonding related failures in these types of material systems occur due to embedded cracks that are perpendicular to the direction of the material property gradation. These cracks are inherently under mixed-mode loading and fracture analysis requires the extraction of the modes I and II ...
Exact solution of rotating FGM shaft problem in the elastoplastic state of stress Akis, Tolga; Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2007-10-01) Plane strain analytical solutions to estimate purely elastic, partially plastic and fully plastic deformation behavior of rotating functionally graded (FGM) hollow shafts are presented. The modulus of elasticity of the shaft material is assumed to vary nonlinearly in the radial direction. Tresca's yield criterion and its associated flow rule are used to formulate three different plastic regions for an ideal plastic material. By considerina different material compositions as well as a wide range of bore radi...
Three dimensional fracture analysis of FGM coatings İnan, Özgür; Dağ, Serkan; Department of Mechanical Engineering (2004) The main objective of this study is to model the three dimensional surface cracking problem in Functionally Graded Material (FGM) coatings bonded to homogeneous substrates. The FGM coating is assumed to be a (ZrO2) ا (Ti-6Al-4V) layer. Homogeneous ceramic, metal ا rich, ceramic ا rich and linear variation material compositions are considered in the analyses. The surface crack is assumed to have a semi ا circular crack front profile. The surface crack problem in the FGM coating ا substrate system is examined...
Modeling of resin transfer molding for composites manufacturing İpek, Hakan; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2005) The resin transfer molding (RTM ) process, in which a thermosetting resin is injected into a mold cavity preloaded with a porous fiber preform, is a manufacturing method for producing advanced continuous fiber reinforced composite products with complex geometries. Numerical simulation of resin transfer molding process is an often needed tool in manufacturing design, in order to analyze the process before the mold is constructed. In this study, a numerical simulation of the resin impregnation process in RTM ...
