Though there are many researches available mainly focusing on bond property, strength of material and fire-resisting performance, the mechanical property of GFRP bolt under freeze-thaw cycle conditions is hardly involved in researches[7-8].
Mechanical property See table 3 for the average value of each group and the change rate of comparison after the test results of tensile property of GFRP bolts are handled.
The degradation of resin also affects the fiber and the property of boding interfaces.
Study on varying pattern From the above analysis, the mechanical property, to some extent, has certain relation with the times of freeze-thaw cycle.
Considering factors such as the pattern of curve, residual, and determining coefficients, the Cubic function-- is used to fit the change of ultimate tensile strength and elastic modulus of bolts after freeze-thaw cycle.

Degradation of properties of the material and/or welded joints of hydro-mechanical equipment is being caused by the simultaneous influence of a large number of factors.
In this paper, the selection of methodology for the rehabilitation of hydro-mechanical equipment is presented based on the previously conducted assessment of state of equipment using the nondestructive testing methods.
In this paper the results of visual testing (VT), penetrant testing (PT) and magnetic particle testing (MT) in order to detect the surface defects, as well as results of ultrasonic testing in order to detect internal defects within welded joints (WJ), or, to put it differently, within weld metal (WM), heat affected zone (HAZ) and parent material (PM) have enabled the determination of causes of degradation of parent material and/or welded joints.

The main goal of the experimental work was the evaluation of the influence of GCPW on mechanical properties of soil stabilization based on the fluidized fly ash.
Mechanical properties were investigated using standard procedures in soil mechanics.
It was concluded, that the studied level of replacement performs critical level, additional increasing of GCPW would lead to a decline of required mechanical properties.
Investigation was carried out predominantly by means of mechanical properties.
Detailed properties of final composites are introduced in Tab. 2.

By measuring the cured polyurethane films absorption and mechanical properties, we determine the conditions for UV curing, 3% TMPME, photoinitiator (2959) and to UV light application time for 30s.
Therefore the films were soft, flexible, with poor solvent resistance and mechanical property [4-5].
The obtained resins had high C=C content and the UV cured films exhibited high mechanical properties and good water resistance.
PEDA the introduction of more double bonds to main chains, these factors make the crosslinking density increases, so that the properties of waterborne polyurethane can be improved.
The UV cured films exhibited high mechanical properties and good water resistance.

The external agent in this study was purposed to extend the setting time and enhance the mechanical properties of geopolymer.
In addition, reactivity of raw material, alkali metal type, and characteristic of microstructure are among the factors that contribute to the formation of efflorescence [2, 3].
At large quantity, the existence of efflorescence crystals will strongly affect the mechanical and durability properties of geopolymer.
Retarder is included to enhance the properties of geopolymer mixture via the extension of setting time and enhancement of mechanical properties.
Degree of reaction controls the rheological and mechanical properties of geopolymer mortar.

The influences on mechanical properties under quasi-static loading and dynamic properties were also investigated.

This condition results in the lower mechanical strength properties of FRA than those of the NFA, thereby inconsiderably affecting the improvement in mortar strength.

Introduction The mechanical property of nanocomposite ceramic tool materials is improved due to the special grain microstructure.
However, the affecting mechanism of sintering process on the microstructure is still inexplicit, it is necessary to simulate the effect of sintering parameters on microstructure of nanocomposite ceramic tool materials.
Sintering temperature is an important parameter affecting grain growth of ceramic tool material, the mean grain size L can be given by the following equation [4]: (1) where γ is grain boundary energy, A the accommodation probability, Z the average number of atoms per unit area at the grain boundary, Vm the volume of specific mol, Na Avogadro’s number, h Planck’s constant, R the gas constant, Ts absolute sintering temperature, ΔSa the activation entropy, Qa the activation energy, t the real grain growth time, L0 the initial grain size at t = 0.
Thus, the temperature factor, kT, has an influence on the probability of grain growth.
The highest sintering temperature is given 1600℃ according to the properties of nanocomposite ceramic powders and hot-pressing sintering experimental equipment.

The comfort requirement of intimate apparel is highly concerned and smoothness, softness, stiffness and drape are the consideration factors.
Therefore, we evaluated the mechanical properties of smoothness, softness, stiffness and drape of the different plied samples and the results were discussed properly.
Thus, the comfort properties of the plied samples are important to determine their usage [1].
