Rubber fibers, description

The reinforcement of rubbers using nylon, rayon, vinyl, and polyester fibers was reported by various authors [10,58,73-75]. Because of the design flexibility and suitable end-use applications, high-performance fibers such as glass, carbon, and aramid also find extensive applications in short fiber-reinforced mbbers. A brief description of some of the major high-performance fibers commonly used in short fiber-rubber composites is given below ... 

The reaction medium consists of molten sulfur/accelerator (N,N-dicyclohexyl-2-benzo-thiazolylsulfenamide)/zinc stearate in the weight ratio 90/5/5. Small pieces of the cord are cut from the tire carefully trimming some of the rubber but leaving a thin, undisturbed surface layer. Eight hours are required for the reaction at 120°C. Samples are removed, scraped off and placed in a 120°C oven to remove the excess ebonite. The treated cords are embedded and sectioned with a diamond knife to reveal the interfaces that relate to the adhesive coating and the tire cord adhesion. The fiber-RFL-rubber interfaces are all observed in the tire cord cross section (Fig. 4.14). A more complete description of this type of study is described in Chapter 5.
