A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix are disclosed. The glass fiber includes a first glass material having a first set of mechanical properties including a first modulus and a first coefficient of thermal expansion (CTE) and a second glass material having a second set of mechanical properties including a second modulus and a second CTE. The second glass material forms a substantially uniform coating on the first glass material. The second CTE is less than the first CTE. The glass fiber is formed by reducing the cross-section of a glass fiber preform of the first glass material coated with the second glass material by hot working. Because of the selected difference in the CTE's, the first glass material imparts a compressive force upon the second glass material, which improves the strength of the glass fiber.
