In conclusion, the incorporation of vanillin into PMMA resin could affect its mechanical properties.
In addition to the antimicrobial properties, the mechanical properties of the appliance are crucial criteria to utilize in clinical uses since a lack of these properties can reduce the appliance's functions and can cause major complications.
A mechanical property evaluation is needed to confirm sufficient properties.
Theoretically, many factors influence the mechanical properties of the resin, such as chemical composition, curing method, degree of polymerization, and storage [10-12].
Summary This study demonstrates that incorporating vanillin into PMMA resin causes a decrease in its mechanical properties.

In terms of mechanical properties of composites with natural fibers, both fiber loading and their orientation in the matrices are important factors.
In this research work, the effects on the mechanical properties of reinforcing quasi-unidirectional salago fiber in epoxy resin were investigated.
In the case of natural fiber reinforced composites, the major factors that can affect their mechanical properties include the type of fiber and matrix materials, the orientation and dispersion of natural fibers, the adhesion or interaction of the fibers to the matrix, the processes involved in the composite fabrication and the void fraction [3].
Similarly, in a study about bi-directional jute fiber composites, better mechanical properties were obtained at higher fiber loading [6].
Aside from fiber content, the length of the fiber can also affect the mechanical properties of fiber reinforced composites [7, 8].

Effect of Poling on the Mechanical Properties of ββββ-poly(Vinylidene Fluoride) C.M.
The differences observed between the two materials suggest that the poling affects the mechanical properties of the material especially in the direction parallel to the polymeric chains and originates changes at a molecular level that remain beyond the melting of the material.
An important issue is the dependence of those properties on the structure of PVDF.
The Young´s modulus at constant polarization obtained from equation 2 for unpoled PVDF, is 0.9GPa ± 0.1 GPa and for poled PVDF is 1.3GPa ± 0.1 GPa, i.e the poling process affects the mechanical properties of the material along the chain direction.
As a result, the Young modulus of the material along the polymeric chains increases but does not especially affect the mechanical properties in the transversal direction, i.e. poling mainly affects the intrachain coupling.
