Static Bending Strength Analysis of the New Self-Healing Composite Gear Based on ANSYS

Abstract

A new kind of self-healing composite gear, namely the short glass fiber reinforced nylon 6 composite gear with 3.5wt% microcapsules, is studied in this paper. Its 3D model is built through the parameterized modeling function of Pro/E software, and then its stress distribution under a certain load is analyzed based on ANSYS, through which the maximum bending stress of the self-healing composite gears is obtained and the dangerous position is located. At the same time the same analysis is conducted on the composite material with no microcapsules. By comparing the analysis results of these two kinds of composite gears it shows that after adding 3.5wt% microcapsules the maximum bending stress of the composite gears decreased by 0.72% which can be seen basically unchanged, and their stress is almost in the same distribution with invariant dangerous position. The above result shows that the self-healing microcapsules have little influence on the static bending strength of composite gears.
