The present study evaluates the toughening capability of electrospun PA66 nanofibers for carbon/epoxy composite laminates subjected to mode II loading conditions at elevated temperatures. Dynamic Mechanical Analysis (DMA) test showed that glass transition temperature produced is in a range ∼60–80 °C. Accordingly, End-Notched Flexure (ENF) specimens interleaved by 50 μm-layer were quasi-static r...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Polymeric cellular materials are used in many different application domains such as transport, sport, food, health and energy. Therefore, the conditions of use these represent wide temperature strain-rate ranges. The mechanical behaviour foams demonstrate a strong dependency to it. In order be able predict dependency, its origin has better understood. For this study, bio-based material, agglome...
Viscosity ($\eta$) is one of the most important properties disordered matter. The temperature-dependence viscosity used to adjust process variables for glass-making, from melting annealing. aim this work was develop a physics-informed machine learning model capable predicting $\eta(T)$ oxide liquids. Instead itself, NN predicts parameters MYEGA equation: liquid's fragility index, glass transiti...
