Among the myriad factors that ultimately influence the global properties of epoxy/Al(OH)3 composites, filler dispersion and interfacial interactions are the most crucial ones affecting the mechanical properties of the composites [3].
The flexural properties of epoxy based composites: (a) flexural strength, (b) flexural modulus.
This special polydopamine modified Al(OH)3 reinforced composite should possess good mechanical properties due to the strong interface adhesion which allowed the stress to transfer across matrix and the thorns.
This suggested that the polydopamine layer play an important role in improving mechanical properties of the composites by strengthening filler-matrix adhesion.

The characteristic microstructure and material component sequences with excellent mechanical, electrical and thermodynamic properties were predicted and screened.
Cu-Cr-Sn, Cu-Cr-Zr and Cu-Fe-P copper alloys with high strength and high conductivity have many influencing factors on their properties, such as matrix doping state, type and content of second phase, microstructure and interface characteristics, deformation and heat treatment process, etc [3, 4].
In this paper, the mechanical, electrical and thermodynamic properties of the characteristic microstructure are predicted by using the multi parameter collaborative optimization criterion of the key properties of the matrix and the second phase [5-7].
The mechanical properties, conductivity properties and thermodynamic properties of characteristic microstructure are predicted by using the multi parameter optimization criteria of matrix and second phase key properties (mechanics, electricity, heat, magnetism and dynamics).
Thermodynamic models of crystal structure, mechanical properties, electromigration and diffusion properties, interfacial bonding properties and temperature dependence were established.

Moreover, to ensure building properties, it is necessary to have same quality mix along the building phases.
This study investigated structural cob mix composition, water content, density, mechanical properties and thermal conductivity.
Knowing the material variability will allow to ensure building properties throughout the construction phase.
The mechanical resistance of cob affects the wall height, which reduces construction time and cost (Hamard et al., 2016).
The study is based on the analysis of structural cob mix composition, water content, density, mechanical properties and thermal conductivity.

The microstructure, hardness and corrosion properties of the nitrided samples were characterised by a variety of analytical techniques.
In particular, the corrosion properties of nitriding samples(420˚C) are five times larger than original samples.
Introduction The martensitic stainless steel are often used in fabricating components requiring high mechanical properties and moderate corrosion resistance, such as cutting tools, valve parts, cutlery and fasteners.
For example, nitriding at a temperature around 500˚C can produce a thick nitrided case on an austenitic stainless steel surface, which significantly improves the surface hardness and wear properties.
While the chromium content in the surface declines, the corrosion will be worse, because chromium content is the important factor affecting the stainless steel corrosion resistance.

The obtained test results show that the substitution of GP waste up to 15% does not affect the mechanical and fresh concrete properties of the concrete and it was recommended that the replacement of natural sand by GP waste up to 15% of any formulation would be favorable for concrete making.
Test results showed workability of fresh SCC has not been affected up to 200 kg/m3 However mechanical properties of the concrete were decreased with the increases in the MD substitution rate.
From the above results it was concluded that the GP substitution rate up to 15% which led to the acceptable fresh concrete properties in terms of workability and also acceptable difference in mechanical properties.
Table 5 Mechanical properties of concrete mixtures Mixture No.
Ø The appropriate substitution of GP waste can lead to the least effect on mechanical properties of the concrete such as compressive, flexural and split tensile strength.

Thermal conditions between the injection part and the mould or more precisely injection part, mould, machine and surrounding during cooling and injection part solidification are important parameters which influence injection part and mould temperature field and affect the structure and properties of the injection part as well as its surface quality, moulding shrinkage and post-shrinkage [1], anisotropy of properties, residual stress in injection part [2,3] which are results of the interaction of flow and temperature factors and so on.
Nevertheless method DSC is at the enthalpy transformations evaluation greatly influenced by methodical factors mainly by setting beginning and the end of phase transformations which determinate curve surface in the DSC thermogram that is directly proportional to enthalpy.
Experimental analysis of the mechanical properties Injection parts mechanical properties in dependence on the cooling conditions (Table 3) were evaluated on testing samples taken from injection parts bottom (Fig. 5) by determination: yield tensile stress, nominal tensile elongation at yield (loading rate 50 mm/min), flexural stress and modulus (loading rate 1 mm/min).
Testing samples were taken from the injection parts (with regard to anisotropy properties in just one direction) by means of cutting tool and eccentric press.
This fat is positive from the injection parts properties uniformity and also from their shape accuracy point of view.

However, the material chosen must be according to the desired mechanical properties and the application [4].
The mechanical properties for all specimens from tensile test are listed in table 1.
However, in this case the behavior of lamination varies with several factors such as fiber volume fraction, matrix material, fiber material and manufacturing processes [14].

These factors change the shelf-life of yoghurt and finally cause spoilage in yoghurt.
The reason of this is that the microbial contaminations due to various effects and the factors within its structure.
On the other hand, the rapidly rising expectations on packaging sector can be summarized as improved barrier properties, heat consistency, high resistance against outer factors, being light, cheap and resistant, being visually attractive, etc.
The type, magnitude and stability of these interactions are effective on determining the physical properties of yoghurt coagulum.
These properties show us that it can easily form a chemical bond with polypropylene.

Design of Static PVDF Micro-force Sensor Electro-mechanical Model of PVDF Sensor’s Physical System.
The inverse model is shown in Eq.5, and the inverse controller can be designed as Eq.6 according to our previous work [6-8], here, R2, R3 and B are all included in the proportional factor K, therefore the design parameters are only related to the R1 and C1, and one can change the factor K as he/she needs in the experiments
The accuracy of force-tracking is usually affected by the variable factors such as input signals, complex contact environment and also the circumstantial noise.
Summary In this paper, based on the inverse-model control method, a static PVDF micro-force sensor has been developed and it possesses good properties such as high linearity, resolution and simple structure.

At First, the influence factors of automobile noise are introduced, and then the major noise sources are all analyzed.
The magnitude of Exhaust noise is related with some factors such as power rating, rotation rate, valve pressure, and varies with the variation load of engine.
The factors that affect the gear noise are so much complicate.
Because the mechanical factors and road surface excitation, noise is made by every component on vehicle.
How to control the noise in the vehicle is very difficult because of the complicate factors.
