Introduction Composite laminates are widely used in aviation and aerospace because of their excellent properties such as high strength weight ratio, high stiffness to weight ratio, low density, corrosion and fatigue resistance, and designable features.
Mechanical linkage has good debonding resistance with no curing residual stress, and it is hardly affected by environmental factors.
Mechanical linkage can increase the weight of structures and may affect the streamlined external shape of airplane.
Mechanical linkage is usually used on thick structure assembly.
This method has some excellent properties such as good debonding resistance, low equipment requirements and good structure strength recovery.

Test batch samples tensile properties compared to a knit fabric.
The Version 1 stack proved to have the highest washing reliability and elastic properties based on test sample results.
During tensile tests, it was seen that the mesh and knit fabric on the commercial suit have contrasting elastic properties (Fig 7b).
Still, the mesh and knit fabric change the suit's elasticity by then also affecting the circuit.
These observations illustrate how unknown factors such as commercial hydrophobic coatings or specialist textile materials used in commercial products can easily interfere with the test results obtained.

The formability response of material is changed due to increased frictional conditions at the sheet/tool(die) interface and the mechanical properties of substrate.
To enhance the formability of the GA steel sheet, the previous works [1-5] focused on controlling several factors such as grain size, crystallographic orientation, temperature, coating thickness and phase composition of the intermetallic layer.
The mechanical properties are evaluated by nano-indentation and deformed specimens were investigated using SEM/EDS analysis.
The failure behavior is related with the volume fraction and morphology of intermetallic compounds and mechanical properties in coating layer.
Improved powdering of the low alloying steel might be attributed to the soundness of interface and the morphology of brittle phases of δ(FeZn10) and Γ(Fe3Zn10) related with mechanical properties of coating layer.

Once a fault happened in these mechanisms, the mechanical failure will affect the graphic information in the sheet.
In order to reduce interference factors, the roller-marks discussed in this paper were mainly caused by the failures and state changes of offset press.
The mechanical strength: the strength and rigidity of the bearing part and will also affect the sheets and cause corresponding roller mark.
The mechanical precision: the accuracies of machining, assembling and regulation of the key parts will affect the stationary of motion and this is the internal cause of roller mark.
It is an important property to describe and identify an object.

And the qualities of pore-forming agents such as pore-forming ability and pore-forming structures under some heat treatment are some of critical factors affecting its performance.
They remained in the bodies, affecting the strength and other properties of the bodies.
As is mentioned above, that is because SiC worked as some additive to its sintered specimen, and hardly affected the porosity of the bodies [7].
What’s more, strength and bulk density of the sintered specimens were affected by the large quantities of remaining pore-forming agents which did not react during the sintering process.
When Li2CO3 of Group A, CaCO3 and CaSO4 of Group D, graphite powder of Group C work as pore-forming agents, they will impose some negative effect on the structure and properties of ceramics because the remains of them exist within the bodies after sintering.

These ionic substitutions could disturb morphology and crystallinity structures which in return affect the properties of the calcium phosphate ceramics.
Various studies have been done to improve the properties of CaP [6].
Zinc ions play significant role as bone growth factor in in vitro and in vivo [6, 7].
These peaks depend on several factors such crystallite size and crystallinity [2].
Our work demonstrate that the desired properties for future biomedical application can be obtained by substituting ions such as zinc through precipitation method.

Introduction The presence of solid ice crystals in permafrost soil is greatly different from thawed soil in term of deformation properties.
The factors affect dynamic strain amplitude of frozen soil.
Among factors, temperature is key factors affecting the ice content.
From Figure 4, when temperature is less than-4℃ and is falling, the curves coincide approximately and dynamic strain amplitude have no change as temperature changes, which indicated that the deformation properties of permafrost gradually stable.
Loads are major factors about causing soil deformation and the deformation development, and dynamic strain amplitude varies with dynamic load size changing.
