To fulfill large bone defects requirements, the ideal biomaterial should combine interconnected porosity, sufficient mechanical strength according to the implantation site, and angiogenic factors release ability.
Mechanical properties evaluation.
A minimal content of 0.3% of apatite appeared necessary to obtain scaffolds with improved mechanical properties.
Mechanical resistance is another critical parameter affecting the implantability of the final device and its in vivo fate.
We show here that apatite addition can improve mechanical properties of the scaffolds without affecting interconnected porosity.

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.

The analysis results revealed that the current was the dominant factor affecting the performance measures (62.87% for TWR and 78.82% for SR).
The combination of the properties of two or more materials produces advanced materials with low density, high strength and stiffness and excellent wear resistance as compared to conventional materials.
While Al-MMC reinforced with carbides (SiC, B4C, and TiC) the formation of unwanted aluminum carbide (Al4C3(s)) (Eq. 1) affects the properties of the Al-MMCs and Al4C3 react with the moisture or water to form aluminum hydroxide (Al (OH)3) (Eq. 2) impacting the integrity of the composites [2]
The hybridization of the Al-MMC is expected to enhance the properties of the composites.
