Aim: Micro-cracks and interfacial deformations occur in the composite material structure because of heating and cooling environments occurring on material surfaces. Considering the environment to which bio-composite materials used in the human body are exposed, it is inevitable that they are exposed to a thermal change cycle environment. Material and Method: In this study, the mechanical behaviors of Silorane, X-Trafil and Valux-Plus bio-composite materials were examined after being exposed to thermal cycles in an artificial mouth environment in the temperature range of minimum 5 °C and maximum 65 °C. Micro-tensile strengths of bio-composite materials after thermal cycle test procedures were determined using a universal micro tensile tester device. In addition, microstructural analyzes of bio-composite materials were evaluated using scanning electron microscopy (SEM). Results: Within the scope of the data obtained as a result of this study, it was concluded that the thermal changes in environments significantly affects the micro-shrinkage behavior of bio-composite materials. Conclusion: The behavior of the matrix structure of the composite material significantly affected the formation of micro cracks. ER -
