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...

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...
