In this work, the objective of the study was to investigate the influence of viscosity on silica dispersion and in relation to mechanical and performance properties of Epoxidised Natural Rubber (ENR) compound.
Results showed that low viscosity of rubber will facilitate further the dispersion of the filler in the system although other physical properties will be affected.
Compound Properties The compound properties of the filled compound are presented in Table 1.
Perhaps the surface area and surface chemistry is the most important factors in controlling the tensile strength.
It is interesting to note that beside of cross link density and rubber filler interaction, the viscosity of the rubber also is one of the factors that influencing the abrasion properties of the compound.

The mechanical properties of the copolymers were affected greatly by the length of PPDO segment.
CA not only keeps some original properties of polysaccharide such as renewability, low density, acceptable mechanical properties, but also shows the relatively good solubility in some solvents and thermoplastic property.
However, the discontinuous degradation rate in human body is one of main factors that limit it's the wide application in medical fields.
The mechanical properties of the copolymer were also examined.
Mechanical Properties of CDA-g-PPDO by Tensile Testing Specimens from CDA-g-PPDOs sheets obtained at 100 °C were met with the uniaxial stretching to find a relationship between the copolymers and the mechanical properties.

Many studies have shown that these factors affect the mechanical properties of the composites [5-12].
Impact properties.
This means that the difference in tobacco species does not have an impact on the mechanical properties of the composites.
Further investigation is needed for the effect of the patterns to the other mechanical properties.
Conclusion The mechanical properties of 3D-printed tobacco fiber-PLA composites were affected by infill pattern and fiber loadings.

The paper aims at providing a critical analysis of the materials widely used for manufacturing orthotic devices, especially for the upper limbs area, which is more exposed to mechanical and chemical factors during daily activities.
In order to relieve pain it is sometimes very important to maintain the segment in a certain position without affecting the daily activities in a significant manner.
In this respect, selecting the proper material when designing orthotics, especially for upper limbs requires considering several aspects, starting with mechanical properties, chemical resistance to every day substances, shape, and last but not least the financial aspect.
Some samples of the most used orthotic devices used for the upper limbs area, especially for fingers are considered for our studies, as people come in contact in everyday life with all kinds of apparently harmless substances but they may affect the properties and quality of the orthotics material.
The behavior of the material in certain chemical aggression conditions may be one of the factors that influence the choice of the orthotic device type.

Surface and size effects are among the factors that make a number of physical phenomena in micro-mechanical design quite different from the macroscopic world.
As such, some factors that are generally ignored in macroscopes must be considered in micro-mechanical designs.
The material properties and mechanical behaviors of microstructures undergo significant changes compared to their macroscopic counterparts.
Scientists need not only learn about the plasticity properties of materials, but must also master their elastic properties.
The development of scanning probe microscopy, particularly atomic force microscopy (AFM) provides a new tool for studying the mechanical properties of a sample.
