Abstract
A glass composition and a glass fiber made thereof have a low thermal expansion coefficient and include a main material, a fluxing material and a reinforcing material. The main material includes silicon dioxide having a percentage by weight of 55%-66% of the glass composition. The reinforcing material includes aluminum oxide having a percentage by weight of 10%-20% of the glass composition. The fluxing material includes magnesium oxide, zinc oxide, and titanium dioxide. The percentage by weight of magnesium oxide is 3%-12% of the glass composition, the percentage by weight of zinc oxide is 0.01%-7% of the glass composition, and the percentage by weight of titanium dioxide is 0.01%-6% of the glass composition. By adding zinc oxide and titanium dioxide, the thermal expansion coefficient of the glass composition can be lowered.
