However, due to the development of new technologies it is increasingly difficult to find a polymer with all characteristics for a particular application, whether for reasons of mechanical properties, ways to made or cost.
The use of fiber like reinforcement in polymer composites to added new properties to the material mainly from viewpoint of the mechanical behaviour: mechanical resistance combined with the minimum weight.
In this case, different processes such as chemical reactions and low molecular weight components can be active, affecting the water absorption kinetics.
In this sense, the aim of this work was to study the anomalous behaviour of moisture diffusion in composite materials reinforced by vegetable fibers using the Langmuir-Type model in a one-dimensional approach and transient, considering the constant thermophysical properties.
The destructive changes usually occurs due to degradation of probable existing physical-chemical interactions between the resin and fiber, as a consequence, there is a shift in the fiber, causing delamination and reduction in the composite material properties.

They present numerous advantages from a metallurgical point of view to high properties.
Two factors affected the hardness: δ-ferrite content and the carbides formed in the weld.

In turn, when processing holes with a special lock, the tailstock can be connected to the caliper and receive mechanical feed.
It should be noted that an important factor that affects the optimization process in this case is the cutting modes, which mainly include the feed functions – S, spindle speed – n and cutting depth – t.
As part of the study, the obtained safety margin coefficient makes it possible to increase the efficiency of procedures for studying the main technical and economic properties of forming samples (products).

The machined surface roughness of SiCp/Al composites is very important for ensuring the mechanical property of functional part.
Thus many researchers are focused on the influence of cutting parameters and volume percentage of SiC particle on the surface roughness of SiCp/Al composites, They concluded that the cutting parameters such as cutting speed and feed rate is the predominant factors to affect the surface roughness of SiCp/Al composites [7,8].

The processes are Stereolithography and Fused deposition modelling After choosing the two processes the next step is choosing the best material that will have the needed properties needed.
The goal of this paper is to obtain a better gear with improved properties, resistance and durability.
The material's performance in tensile tests also demonstrates how fiber alignment influences tensile properties; by efficiently transferring stress within the composite matrix, fibers aligned parallel to the load-bearing direction increase strength.
Because the internal fiber reinforcement layout, layer arrangement, and fiber density can change the Onyx composite's stress-strain response, these factors are critical to optimizing tensile strength.

With bottom blowing time and bottom blowing flow as object to do single factor experiment, the relationship between the nitrogen content in steel smelting process and the bottom blowing time, the bottom blowing flow were studied.The research results show that when the other conditions must be, the nitrogen content in steel increases with the bottom blowing time increasing gradually, when the bottom blowing time reach more than 35 min, the variation of nitrogen content in steel decreases.
Introduction High nitrogen steel because of its excellent mechanical properties and corrosion resistance in recent years has received the widespread attention at home and abroad.
Results and discussion Effect of bottom blowing time on the nitrogen content of the high nitrogen steel With bottom blowing time factor as an object do single factor experiment, in the bottom blowing flow rate of 0.16m3/h, under the different pressure and temperature of test results it is concluded that the relation curve of the nitrogen content in the steel smelting process and bottom blowing time, as shown in figure 2.
This is because in the bottom blowing nitrogen smelting process, with the increase of bottom blowing time, the nitrogen content in steel is gradually close to the saturation levels Fig.2 Influence of bottom-blown time on nitrogen content in steel Effect of bottom blowing flow on the nitrogen content of the high nitrogen steel With bottom blowing flow factor as an object do single factor experiment, the relationship between nitrogen content in steel and the bottom blowing flow is shown in figure 3.From figure 3, it can be seen that nitrogen content in steel increases gradually with the increase of bottom blowing flow , when the bottom blowing flow reaches more than 0.24m3/h, the nitrogen content in steel is close to the maximum value and no longer changes with bottom blowing flow.
At the same time, also known from the analysis of variance, bottom blowing flow had significant impact on increasing nitrogen to liquid steel Bottom blowing nitrogen gas flow does not directly affect the steel liquid nitrogen absorption speed, but the increase of the bottom blowing flow increases the stirring intensity of liquid steel and the degree of dispersion of nitrogen gas bubbles in the liquid steel.

Introduction Metal/carbon Nano-composite films have attracted a significant attention for decades because of their unique mechanical, chemical and electronic properties[1,2,3,4,5] which have potential applications in many fields.
The association between the matrix and encapsulated metallic phase can improve the overall properties of the composite films which cannot be achieved by them individually.
The chemical composition, structure and the mechanical properties of the Nano-composite films at different C2H2 flow rate were investigated.

The best mechanical property of the films was obtained at 50 sccm with the best hardness of 21.6 GPa, the highest H/E of 0.1 and the highest ERP of 0.5.

Fig. 1 Service of cloud-based mass customization service platform Parallel processing of product configuration There are many cloud-based product configuration problems to be solved: (1) Because the relatively large correlation between product configuration data in computing process, The overall performance would be affected by so large amounts of data transfer between nodes; (2) How to ensure data transmission security between the data nodes; (3) The parallel split of MAP is affected by the strong correlation between the configuration data.
In addition, associated types also can be defined by establishing the associated objects between brother PFSCs and assembly properties between instance objects of the brother PFSCs can be expressed by use of the adjacency matrix representation.
So we should consider a variety of factors which affect the effect of the service in the cloud-based mass customization service platform and comprehensive application of the factors and parallel processing so that we can more effectively improve the speed and response of services in the cloud-based mass customization service platform.
