At present all the evidence that artificial sports grass can be a good run

The Park sports grass Allianz is the world's first professional English football club TurfSoccer artificial turf.

The live demonstration of the park's long-term users of Allianz Saracens rugby team in order to host the European Cup, Rugby, Rugby Super League the club invited 12 representatives came to the stadium to watch the turf, and access to information so that the rest of the club. From New Zealand, South Africa, England, Scotland, Wales rugby officials will focus on the specific circumstances of this venue.

Saracens rugby team CEO of Allianz park's long-term users Griffiths stressed: the rugby world seen artificial sports grass park Allianz will certainly feel a kind of open horizons. Even recognized as the most conservative of the South African rugby head of rugby circles also try to find ways to reduce the huge costs of artificial grass maintenance cost.

At present all the evidence that artificial sports grass can be a good run, we expect in the next 3-5 years, the main rugby stadium have become artificial grass.

Club using the artificial grass in the United States Football League (NFL) 14: the probability is very low, but nobody artificial sports grass TurfSoccer football player injuries on artificial turf.

How to determine performance advantages and disadvantages of artificial sports grass

How to determine performance advantages and disadvantages of artificial sports grass

artificial grass surface with natural grass does not seem much of a difference, but in fact really need to distinguish between the two specific performance, which is artificial grass birth of starting point. As technology continues to progress in this regard, there is a growing focus on the actual performance of the TurfSoccer artificial sports grass. Whether safety, the most important factor in the above sports or play users are comfortable; For professional athletes, sports performance, and, apart from the two outside are equally important. Specifically, there are the following:

1, comfortable
Artificial sports grass grass fibers more flexibility to fit the natural grass, the more comfortable, while reducing the risk factor of the movement.
2, security
Including abrasions and burns caused by the movement of heavy metals exceeded; former a intuitive visual impact on the safety of users, while the latter should superscalar be great harm both the user's health and the environment. Testing laboratories in Europe are very strict standard requirements for heavy metal content, by contrast, the value of most domestic testing laboratories for the detection of heavy metal content is too broad.
3, TurfSoccer artificial grass sports performance
a. ball rolling
angle ball rebound, including angle
c. venues shock absorption capacity
the d. venues longitudinal deformation
e. artificial grass venue rebound performance

With the increasing of the production technology, the performance of the artificial sports grass becomes closer and closer to natural grass, and thus more and more widely used.

artificial grass fiber content on the friction and wear properties of composite materials

artificial grass fiber content on the friction and wear properties of composite materials

Wear performance of fiber filled polymer composites content is gradually increased resistance to abrasion resistance as the fiber content increased, when the content reaches a certain degree of anti-wear resistance with content increased gradually decreases, ie cellulose to improve the wear resistance of polymer composites, the content of one of the best content. Arkles et al [12] showed that, when the volume fraction is increased to more than 15% longer wear rate decreased with the improvement of the content. ahadur also found that 10% of the fiber-reinforced polyester lowest wear rate and the wear rate of the material is reduced accordingly. Analysis: When the fiber content is too low, the fibers due to tensile or shear fracture, enhance the effect is not obvious; while the fiber content is too high, increased fiber wear debris and fracture the fibers are detached from the matrix, destruction of the composite material and The coupling member is formed between the transfer film, and thus lead to increased wear.

the performance of the different types of artificial grass fiber-filled polymer material

As a reinforcement of the polymer material, the general requirement that the fiber has a high strength and modulus, and can not react with matrix and the matrix to form a good interface, also requires that the fiber has a high abrasion resistance and hardness as a wear-resistant material. More research is mainly concentrated in the glass fibers, carbon fibers and aramid (Kevlar) fibers, etc.. As early as in the sixties and seventies, the scientists found that the carbon fiber filled polymer materials can improve the thermal conductivity and thermal deformation capacity, reduce the wear rate of the material. Sung et al [13] compared the Kevlar-49 and graphite filled epoxy composite wear performance, found that the The Kevlar fiber epoxy can wear rate decreased to the same level and graphite filled epoxy, can get lower friction coefficient. Cirino et al. [14] The results of the study show that the carbon fiber-filled polymer material available wear rate and coefficient of friction lower than the glass fiber filled, that there are two reasons, first, because carbon fibers can play interface lubricating effect, and the other regard, glass fiber breakage and pull will cause more severe abrasive wear. Wishwanath [15] Polyvinylbutyral the ester modified phenolic resin matrix, glass fiber, high strength carbon fiber and Kevlar-49 three fiber reinforced materials under different friction conditions. With the rise in the rate of friction, the temperature of the composite material is also rise, resulting in softening of the matrix material, or even charring, so that the interface of the fiber and matrix loose under the action of friction, the occurrence of fiber breakage and shedding. In these two effects, the structural integrity of the composite material is destroyed. The glass fiber-filled phenolic resin of this damage occurs in the friction rate of 12.94 m / s, while the case for carbon fibers and Kevlar fibers is filled, this destruction occurs in the friction rate of 17.8 m / s. Analysis found that the morphology of the friction surfaces, glass fiber reinforced composite material surface roughness of 0.13 microns before abrasion to rise to 0.26 microns after abrasion, the surface roughness of the carbon fiber and Kevlar fiber filled were 0.17 and 0.11 microns . A corresponding wear rate relationship is Kevlar <carbon fiber <glass fibers, observation of the electron microscopy of the worn surface explains the different mechanisms of the three fiber-reinforced. Friction surface can be observed in the case of carbon fiber and glass fiber filled, a lot of breakage of the particles and fibers, and Kevlar fibers filled composites little wear surface. Description toughness Kevlar fibers can more effectively resist the shearing force of the frictional process while the abraded particles are also unlike glass fibers and carbon fibers as easily form a severe abrasive wear. On the friction coefficient is the opposite result, the friction coefficient of the filling material of glass fiber and carbon fiber filler material less than the Kevlar fibers, the reason may be to breakage and shedding of the fibers play between the friction surfaces due to the smooth surface and a hard rollers, so that the friction coefficient decreases.
