The Rubber Compound Combination To Strenghthen Tire Valve of 80/90 R-14

Abstract

Abstract Tires are part of the wheel of the vehicle in direct contact with the road surface. Tires are the basis for supporting vehicle loads. The basic material of the tire is rubber so it has elastic and soft properties, strong but yet susceptible to taper and sharp objects. Minor damage to the tire will cause air leakage, and its can occur in all parts of the tire. This study discusses tire leakage caused by valve damage. Valve damage is caused by high pressure, lack of pressure, inner tire leakage or shock load collision which causes the tire valve to release. Reused tire damaged in the valve section can be repaired with modifications of the worn and damaged valve. The addition of plastic-coated compound to add strength and toughness of the valve, was applied to get the benefits of tire recycling. The added layer includes a plastic layer, compound and balloon layer. The three layers are tested to find out the layer that is able to increase the strength of the valve more significantly. Tire valve pressure testing which is coated with plastic can have greater strength than other composites.
