Research and comparison of blade natural frequencies is made in different rotational working conditions taking into account external factors such as the rotational inertia force.
At present, most of large blades are made of composite materials of fiber reinforced plastic (FRP), FRP has the merit of high specific strength, good fatigue properties and well damping properties.
The mechanical properties of glass fiber reinforced plastic materials as shown in Tab.1: Tab.1 Material Character of FRP Material Ex Ey Gxy Poisson Density 7:1 FRP [Pa] [Pa] [Pa] 0.22 1950[kg/m3] 1:1 FRP [Pa] [Pa] [Pa] 0.14 1950[kg/m3] 2 Modal frequency analysis of the blade 2.1 Additional stiffness The inertial centrifugal force caused by the blade rotary motion, wind load and other loads of the coupling action increases when the wind turbine rotating, it’s increasing the blade stiffness as well appearing stiffening effect.
At the same time, the different thickness of layers from the tail to the tip and the change for sections of blade web also cause blade stiffness and quality distributed unevenly , therefore, changing for layers in cross section characteristic and the structure performance will affect modal vibration mode of blade and the changes for all order natural frequency.
The results showed that the blade in operation won't resonate to damage, stress stiffening of large wind turbine blade in operation effects on the modal frequency significantly, which cannot be oversight in practical application; and the layer angles of the blade of wind turbine can change the stiffness of blade, and affect the modal frequency, which means modal frequency of the blade can be devised.

Here we draw attention to the development of smart materials with embedded
vasculatures that provide multiple functionality: volumetric cooling, self-healing, mechanical
strength, etc.
As length scales become smaller, dendritic vascularization provides dramatically superior volumetric bathing and transport properties than the use of bundles of parallel microchannels.
The current literature reveals a surge of interest in bio-inspired designs of flow architectures that promise superior properties, for example, distributed and high-density heat and mass transfer.
The tube lengths decrease by a factor of 1/2, from the largest (L0), to L1 = L0/2, L2 = L1/2, etc.
The flow in all the channels is in the Poiseuille regime with constant properties.

Consequently, these problems will seriously affect the lifetime and durability of the coating.
Therefore, How to improve the interfacial properties of camouflage coating and keep it functional has become a prior question in the research of military camouflage coatings.
Xia Juan[11] has systematically studied the contamination principal and influencing factors of paintings by using the widely used acrylic based emulsion coating.
After all, it is obvious that the interfacial properties of a coating have important influence on its whole performance.
Obviously, nano- TiO2 turns out to be somehow effective in improving the interfacial properties of the coating within the range of concentration tested in this experiment.

However, its mechanical and dyeing properties are poor.
The addition of RIFs always causes bothersome fillers aggregation [4], which would cause serious deterioration of mechanical properties.
Therefore, the mechanical properties of the iPP/ROF blends are possibly better than those of RIF- or rubber-modified iPP blends.
The aim of the study was to achieve the uniform dispersion of this novel phenolic ROF powder and then to improve the mechanical and dyeing properties of its blends.
It is always detrimental to the mechanical properties of blend if the filler particles retained this state in the corresponding blends.
