dc.description.abstractIn this study, impact-fatigue behavior, variations of dynamic, mechanic,thermal properties and fracture morphologies of original polymer composite andpolimer composites which were exposed to environmental conditions wereinvestigated.Impact fatigue behavior of unidirectional carbon fiber reinforced PEI compositeswere investigated by low velocity repeated impact loadings at the energy levelsranging between 0.54 ? 0.94 J. After impact fatigue the fractured cross section oforiginal composite were investigated by Scanning Electron Microscope (SEM).Impact fatigue behavior of climatic aged unidirectional carbon fiber reinforced PEIcomposites were investigated by low velocity repeated impact loadings at the energylevels ranging between 0.54 ? 0.94 J. Beside this, variation of thermo-mechanicalproperties of the material after climatic aging were investigated by dynamicmechanic thermal analysis.Impact fatigue behavior of thermal aged polyetherimide (PEI) matrix compositeswere investigated by low velocity repeated impact loadings at the energy levelsranging between 0.54 ? 0.94 J. Beside this, variation of thermo-mechanicalproperties of the material after thermal aging were investigated by dynamic mechanicthermal analysis. After impact fatigue the fractured cross section of thermal agedcomposite were investigated by Scanning Electron Microscope (SEM).Keywords: Impact-fatigue, polymer composite, thermoplastic matrix, fracturemorphologyen_US
