In this paper we propose a composite reinforcement method to improve the mechanical properties of circular saw blades.
Actually there are many other factors which also have significant effects on the mechanical properties of saws.
Other parameters, such as the geometrical parameters, segments and slots in saw blades and so on, can affect the mechanical properties of saws more or less.
In the design of a better saw blade, we plan to consider all these factors in our further research.
Conclusions Based on the proposed composite reinforcement model, simulation results and the analysis of the mechanical properties of saw blades.
