There was almost no void of bubble defects, no excess resin flow, and a smooth transition was established between the carbon fiber and the matrix resin layers while allowing the full mechanical strength properties to be realized.
Due to the large volume of printing, defective preforms were expected to be produced, and the ranges in qualities of the printed preforms are one of the key quality factors of the additive manufacturing method.
Although the attention to the subject of observation has shifted from the mechanical properties of the molded preform towards the surface appearance and shape, it was necessary to observe the internal structure of preforms with more ideal and less ideal appearances.

Description of material properties is a key factor in determining the coefficient of friction, coefficient of friction and speed.
Curves of the amount of wear at the same number of turn Taking into account we tested selected load (100N) is not high, it can be summarized to this test of speed on the friction properties of rubber as follows : constant in the low load conditions , the dry friction CR/EPDM blends - steel with the friction coefficient increases with the speed in a range of fluctuations .
The impact of temperature on the friction performance of CR/EPDM blended Sliding process, the working conditions (load and speed), friction and wear is often due to temperature rise caused a lot of material mechanical properties (elastic modulus and hardness), and lubricating properties as the interface temperature rise degradation, thus affecting their tribological behavior [9].
Loads must change the speed of the test , with increasing speed , the test conditions of rapid temperature rise would have an impact , when the speed exceeds 300r/min has been difficult to clearly observed in the friction coefficient increased with the speed of growth ; A certain speed , to change the load test , when the load is low , the impact of load variation on the friction coefficient significantly in the temperature on the friction coefficient , when the load increases to a certain value , the change of load on the friction coefficient is weakened the temperature change has become a major factor influencing the fluctuations in the friction coefficient , but the determinants of the coefficient of friction , the material properties.
An investigation of mechanical and rheological properties of EPDM/PVC blends: influence of anhydride additives, mixing procedure and EPDM form.

INTRODUCTION Ni-base superalloy CMSX-10 is a third generation single crystal material for advanced gas turbine blades with excellent high temperature mechanical properties.
So high-temperature exposure should be considered in study of the mechanical properties.
The effect of prior exposure in high temperature air environment on the room temperature mechanical properties has been reported[1].
The results show that the fatigue crack growth behaviour is not affected by the air-exposure at 1100͠ till 1000 h. 3.2.

As shown in experiments, the size of fragments of primary carbides affects the properties of the matrix after heat treatment and the precipitation of secondary carbides.
The above properties are conditional on achieving a very fine structure.
As shown below, it is secondary carbides which control the resulting properties.
As they govern the above-named properties, they should to be analysed thoroughly.
Many factors play a role here, the most important ones being the lighting, good specimen preparation and the quality of the imaging equipment.

And the calculated value and vibration signal spectrum diagram compares analysis, find out the fault location and machine determine the fault properties.
So once found that the products processing machine precision (size accuracy and geometrical accuracy) or surface roughness in short of asks, eliminates human factors, mainly from after the operation status of machine itself to find reasons.
We decided to adopt the mechanical fault diagnosis technology to find fault location and machine tools [2], we determine the fault properties of the first use of machines and machine investigation.
Using JGZY - 1 mechanical fault diagnostic instrument, test system shown in figure 2.
Figure 5 for lathe 560 R.P.M. sensors to walk the knife box signal spectrum diagram, vibration filter the biggest frequency signal for 313.75 Hz, but also corresponding to verify it affected for processing gear.

Introduction In addition to the hereditary character of the plant itself, the variation of environmental factors such as illumination, temperature, moisture and CO2 concentration can also affect the growth and development of the plant directly [1].
The real-time values of environmental factors such as the illumination degree are shown in the picture.
When the system is in the operation status, the real-time values of environmental factors will be displayed in the textbox “####”[11].
Double click the alarming window to pop up the configuration property page of the alarming window, so as to conduct setting for operational properties and condition properties.
The values of environmental factors in the greenhouse are collected to execute the operation of the agency facilities through remote control over the greenhouse, thus reaching the purpose of regulating the environmental factors in the greenhouse.

Introduction Steels are the most widely used materials in construction, mechanical, tooling, aircraft and chemical industries because of their good mechanical properties and relatively low cost [1].
Moreover, the coating layers also can be peeled off because of weak mechanical bonding inherent to thermal sprayed coatings [4]; these are serious problems particularly at high temperatures and in molten salts corrosion environments.
It also can improve the protective properties and bond strength of the sprayed coatings without affecting the substrate properties and dimension with the high degree of automation and controllability of process.
The structure of coating is a key factor to affect the wear and corrosion resistances of coatings.

Due to its good mechanical properties, PLA is a potential substitute to some usual polymers such as PET.
Thermomechanical history experienced by the polymer during processing drastically affects its relative crystallinity.
Then, from an Arrhenius plot of the shift factor aT, the activation energy was found to be 110 kJ/mol, in accordance with the literature from Gu et al. [2].
Furthermore, the critical value of the mechanical work needed for the transition depends on the Molecular Weight Distribution (MWD) of the polymer, Mykhaylyk et al. [10].
Indeed, the morphology governs not only the geometry but also the gradient of rigidity and consequently the mechanical properties of the final product.

It is shown that the bonding length affect the flexural properties of composite tubes.
The flexural properties of bonding composite tubes increased with the increasing length of reinforced pieces L2.
However, few researchers investigate the composite tube of adhesive bonding and mechanical properties after the connection.
Fig.2 shows the typical compression properties load-displacement curves of specimens.
As the increase of deflection, deformation properties changed from elastic deformation to plastic deformation.
