Is artificial grass greens perfect it? Of course not.

The biggest shortcoming of the artificial grass small Friends of challenging golf. artificial grass woven by machine, whether it is grass density, height, lodging direction are consistent golf enthusiasts to master the law after it will be very easy to push the ball into the hole, so that the golf buddies conquest satisfaction enough strong. Of course, our designers will take a change in the slope of the method, to create a different degree of difficulty of the greens. Artificial grass greens on the location of the hole is fixed. And the hole location, once fixed, generally can not transform real grass greens, you can use out of a different hole openings in different locations of the greens. Guests at different times to play the hole face the same challenges he was not the same, there have been fresh.

The continuous fibers are arranged in the polymer matrix, with respect to the direction of motion of friction the three Ordering manner [16], one is parallel to the rubbing movement direction (P), one is parallel to the friction surfaces, but perpendicular to the rubbing direction of movement (AP), the other one is perpendicular to the friction surface (N). For bidirectional woven fiber, there are four friction, respectively, that is: parallel to the friction surface and parallel to the fibers arranged in the direction (P), parallel to the perpendicular to the friction surface arrangement (AP), and perpendicular to the friction surface are arranged in parallel (NP), and perpendicular to the friction surface and perpendicular to the rubbing direction (NAP).

Friedrich et al [17] a detailed study of the wear properties of graphite fiber filled PEEK elaborated the various permutations of the wear properties of materials and their different mechanism. In all the arrangement, the wear rate of the composite material with the PV value and the temperature rise of friction increases. Under the same conditions of friction, wear rate of the P direction lowest and highest wear rate in the AP direction, even more than unfilled PEEK, the wear rate of the N direction in between, but wear than pure PEEK rate. The friction coefficient is substantially independent of the the PV and friction effects of temperature, the same time, the friction coefficients are obtained in the three types of alignment higher than that of pure PEEK. Based on the different properties of the material, Friedrich et al proposed the wear mechanism of the different directions, that in the three types of alignment are fibers from the main bearing effect, therefore, for a P direction, cracks and fracture development in the vertical direction of sliding, and therefore not continuous, therefore the distance between the cracks is not likely to cause the shedding of the fibers, in the N direction, the fiber reinforced material, the shearing action of the interface is reduced, so that the wear rate decreased, but the stress concentration at the same time cause fiber breakage and pull out the interface layer at the fiber ends, and become a major wear.

For woven fiber reinforced composite material, the wear rate can be reduced to the unidirectional fiber reinforcing material is 1/6, and the friction coefficient is also decreased accordingly. Meanwhile, the woven fiber reinforced composite material wear performance showed obvious isotropic, little difference in the wear rate of the wear surface, and through the observation of the worn surface, indicating that the braided fiber consolidated in all directions of the unidirectional fibers , so that abrasion resistance is greatly improved.
