The strength and strains of the wood-cement composite primarily depend on the main technоlogical factors such as the used type of binder and wood filler, the method of wood filler preparation, the method of molding, the conditions of hardening.
The strength and strains of the wood-cement composite primarily depend on the main technological factors such as the used type of binder and wood filler, the method of preparation of wood filler, the method of molding, the conditions of hardening [1,2,12,13-17].
It is known that high-valence cations can be adsorbed by wood fibers, improving wood’s adhesive properties.
Consequently, this property of treated wood can be used in its interaction with cement in a wood-cement composite and significantly affects its strength, especially in the early periods of hardening.

Another factor affecting the shrinkage, appointed by R.J.
A number of factors have been identified that affect the development of residual stresses and the dimensional stability of moulded parts.
Bawiskar et al [4] compared the levels of warpage developed in parts made from different thermoplastics and concluded that the cooling phase was the most important factor.

Research on Ceramic Manufacturing for Creating and Solving Ceramic Formulations Model Junyao Ye 1, a, Kening Liu1, a,Yinglian Wang 2,b 1 College of Information Engineering, Jingdezhen Ceramic Institute, Jingdezhen, China 2 College of Mechanical and Electronic Engineering, Jingdezhen Ceramic Institute, Jingdezhen, China a lailul@163.com, b sdwyl@126.com Keywords: Ceramic Formulation; Optimization; Formulation Model; Matrix Solving.
The structure and composition of ceramic materials determine their properties, any material in the ceramic formulation has a slight change, which will have an impact on the performance of ceramic, so the optimization on the design is very important.
The chemical composition of the blank is the main factor affecting the performance of ceramic products, while the main factors affecting the performance of ceramics include minerals, micro-particles and colloidal content index.
In the design on ceramic formulation, we focus on the content of chemical composition calculated by the raw materials, not considering factors such as the price of raw materials.

Sintering behavior and mechanical properties of the forsterite bodies were evaluated from 1200ºC to 1500°C.
This apparently indicates that mechanical properties were not governed by densification after 1400ºC.
Grain growth was the main factor that affected the improvement of mechanical properties beyond 1400ºC.
The comparison between the mechanical properties of forsterite with cortical bone and HA is shown in Table 1.

The elastic properties of {[(TeO2)0.7 (B2O3)0.3]0.8(SiO2)0.2}(1-x)(V2O5)x glasses are investigated using ultrasonic pulse echo measurements and their elastic properties have been characterized at room temperature.
Introduction The propagation of ultrasonic wave in solids such as glass provides valuable information regarding the solids state motion in the material and has been considerable interest to understand the mechanical properties.
Vanadium-containing glasses is of interest as it present interesting semiconducting properties to the materials.
Another factor affecting Poisson's ratio is the average cross link density.

The influence of these factors was investigated using the Taguchi method, an orthogonal array L8.
The structural properties were recorded and analyzed by an X-ray diffraction (XRD) generator with a grazing incidence angle of 1°, and a scanning rate of 5°/min.
Another factor that affected the formation of W-V2O5 targets was the gas environment.
Control factors Surface temp.

Electrical Properties Investigation of Unsaturated Polyester Resin with Carbon Black as Fillers R.
Their effect on the electrical properties of the polyester compositewas analyzed.
The electrical properties of polymer composite depend on the conductive fillers distribution among polymer matrix and as a result on the method of filling.
The arrangement and dispersion of filler in the polymer matrix hold an important role as a properties controller of the resulting composites.
Conclusion Electrical properties of polyester resin with carbon black as fillers were investigated.

Heat generation due to frictional contact on seal-ring surfaces is a major factor that causes deterioration of face seals and shortens their service life[1,2].
Carbon is the most commonly used seal ring material because of its superior wear and corrosion properties.
Friction torque value reflects friction condition of the seal mating rings and is an important parameter that affects seal performance and service life of mechanical seals.
Face temperature rise of the mechanical seals is an important parameter in examining the friction condition between the seal faces.
It was found that compared with the untextured conventional mechanical seals, the friction torque and the face temperature rise of the laser-textured mechanical seals with micro-pores are much lower.

The existence of warpage not only affects the appearance of plastic products, but also affect its mechanical properties and ultimately seriously affect the life of the product[1].
The warpage generation, like many other factors, such as the melt temperature, mold temperature, injection time ,gate location and etc.
How to balance these factors to eliminate or reduce the warping deformation, more and more by manufacture and academic concerns.
The results of research by domestic and international shows that many factors affect the warpage, which Moldflow flow analysis obtained after the temperature field, shear stress field uniformity and other factors on warpage have major impact[12].

The differences of thermal and physical properties between aluminum alloys and stainless steel result in different temperature and hardness profiles.
Stacking fault energy (SFE) of the materials can affect dislocation interactions or strength during thermo-mechanical processing.
The thermal properties can affect the overall temperature distribution and contribute strength drop.
Increased temperature affected precipitate sizes and shapes in the welded zone and decreased overall strength.
