Synthetic turf. The feasibility of using shredded scrap rubber as a component in synthetic tmf for play grounds, factory floors, and park paths had also been investigated. The product Tire Turf was prepared by mixing shredded scrap tires with a binder such as polyurethane, latex, or asphalt... 

Tapes or yarns for artifidal grass sports fields require attributes of both pigmented textile fibers and woven tapes long-term nonfading color and physical properties. This synthetic turf is popular because of its low maintenance costs, but the plastic must last several years under harsh use conditions for the high installation costs to pay themselves back as savings. Case 4.1 reviews such an application of PE turf [4-12, 4-14). 

The use of tyre crumb in the manufacture of sports surfaces can raise questions related to health and safety issues. For example, synthetic turf composed of a layer of tyre crumb and ribbons of PE fibres has been installed in many playing fields in the New York City area in the USA [77]. Concerns were raised that the VOC present in the rubber could cause problems when released into the breathing zone of the players, particularly on hot days. There were also questions...

These grass-like and resident instadations require substantial amounts of synthetic materials. A typical sports field covered with artificial turf requires approximately 15,000 kg of fabric, 15,000—30,000 kg of shock-absorbing underpad, and 5,000—10,000 kg of adhesive and seaming materials. The artificial surface for a 0.40-km miming track may require 50,000—70,000 kg of materials. Paint striping and marking of turf, tracks, and courts cad for additional materials. 

Typical static friction coefficients are given in Table 1. These data demonstrate that the absolute traction values for synthetic surfaces are satisfactory in comparison with natural turf, provided that shoes with the appropriate surfaces are employed. Synthetic surfaces by virtue of their constmction are to a degree directional, a characteristic which, when substantial, can significantly affect both player performance and ball roU. This effect is evident in a measurement of shoe traction in various directions with respect to the turf—pile angle. Some traction characteristics are directiy affected by the materials. 

These needs led in turn to investigation of ways of preparing synthetic surfaces so that in behaviour they would be very similar to natural lawn or turf. The factors examined in this connection included the heights to which sports balls would rebound, the resistance to balls rolled over the surface ( ball drag ), and the absorption of impact. All were found to depend largely on the method of construction of the synthetic surface, including its underlayers—the correct...

Sports activities would be different today without synthetic polymers. Balls, uniforms, artificial turf, bandages used to wrap sprains, and nets used in hoops and goals are usually made of synthetic polymers. 

Following the use of Monsanto s woven PP Astro Turf at the Montreal Olympics in 1976, artificial surfaces have been accepted at World Championships level in hockey. Cricket is often considered a traditional and conservative game, but in fact a great many synthetic surfaces are now used. The acceptance of synthetic surfaces in soccer has been somewhat slower. The first synthetic pitch installed inside a stadium in England was by Queen s Park Rangers who used a PP omniturf surface. This was made of tufted PP rather than woven or knitted, with a pile of about 20 mm. Once laid, graded sand was spread into the carpet to within 1-2 mm of the surface to completely fill the pile. 

TRM TRMs are thick structures composed of fused or stitched polymer nettings (often filled with polymeric fibers), randomly laid monofilaments, or yams woven or tufted into an open, dimensionally stable mat. The dimensional stability produces a stiffer but much stronger mat. These flexible, synthetic mats are designed to be used in conjunction with topsoil and seed or turf to create strong, durable, and continuous sod—root—mat matrices which can provide higher long-term erosion protection than grass alone.
