Simulation-based verification of homogenization approach in predicting effective thermal conductivities of wavy orthotropic fiber composite

摘要

In this work, applicability of homogenization approach is verified with the micromechan-ics approach by considering wavy orthotropic fiber composite. Thermal conductivities of T-300 orthotropic wavy fiber composite are determined for micromechanical model and compared with the results obtained by two stage homogenized model over volume fraction ranging from 0.1 to 0.6. Also, a methodology is suggested for reducing percentage deviation between homogenization and micromechanical approaches. Effect of debond on the thermal conductivities of wavy orthotrophic fiber composite is studied and compared with perfectly aligned fiber composite for different volume fraction. It is observed that results obtained by the homogenization approach are in good agreement with the results obtained through micromechanics approach. Maximum percentage deviation between homogenized and micromechanics models is 2.13%.
