  • Accelerated aging of test specimens has always been the staple method for determining long term compatibility for any material in a given range of process conditions. The application of accelerated aging is to simulate real time conditions in an accelerated manner utilizing more severe conditions while maintaining consistency between the test specimens to minimize any unintended deviations of these parameters from target conditions. This thesis explores various designs for holding tensile test coupons and loose fibers along with their advantages and disadvantages. A brief discussion of the fiber aging fixtures are explored and compared. The tensile test coupon aging setup is investigated and described in detail with the use of temperature logging, visual dye tests, and computational fluid dynamics to quantify its effectiveness at maintaining fluid homogeneity and the aging conditions. Initial trials of both the fiber fixtures and tensile test coupon aging setups are discussed along with their initial issues and solutions. As the experiments are ongoing as of writing this thesis, the finalized results are not available for discussion and are also not in the scope of this thesis.
