The high modulus, dimensional stability and cross section properties of glass fibers have made possible the development of dimensionally stable power transmission belting. In addition, the use of glass fibers as a belt material for tires has improved abuse resistance, tread wear and handling characteristics. Chopped impregnated glass fiber bundles have also found application as reinforcements for tread stock in off-the-road tires.
In this paper physical property characteristics of glass fiber and rubber stock containing chopped glass fiber will be discussed.
