摘要: Functionally graded carbon nanofiber-phenolic nanocomposites (FGN) with four different gradient patterns and the same total nanofiber (CNF) content geometry were designed fabricated. A Non-graded nanocomposite (NGN) was also fabricated for comparison purposes. Microstructural characteristics examined by optical scanning electron microscopy. Temperature-dependent thermal conductivity heat capacity of FGN components measured used in finite element analysis. analysis transient behavior FGNs NGN subjected to sudden temperature changes performed investigate effects compositional on field. The model validated using a custom-made experimental setup. results showed that gradual decrease CNF from temperature-exposed side other had lowest field time.
