Evaluation of transverse thermal conductivity of Manila hemp fiber in solid region using theoretical method and finite element method

The transverse thermal conductivity of Manila hemp fiber in solid region Ksf was evaluated using theoretical method (Hasselman–Johnson’s model) and finite element method (FEM). It was found that the results of them are similar to each other: 0.1847 W/(mK) from Hasselman–Johnson’s model and 0.1849 W/(mK) from FEM. The evaluated data of Ksf was used to estimate the transverse thermal conductivity of Manila hemp fiber composites compared with the experimental data showing good agreement.

► Microstructural parameters of Manila hemp fiber is measured statistically. ► Hasselman–Johnson’s model is applied on the thermal conductivity of natural fiber. ► Equalization transformations are found on the thermal conduction across hemp fiber. ► First evaluate transverse thermal conductivity of Manila hemp fiber in solid part.
