T glass contains a higher percentage of silica (SiO2) and alumina (Al2O3) than general-purpose E glass used for composite materials. As a result, its fiber displays highly advanced mechanical and thermal performance.
Like carbon, aramid, and other fibers, T glass is efficient as reinforcement for advanced composite materials and is used by itself or as a hybrid with carbon fiber in aerospace and sports.
T glass is also used in high-performance electronic materials for its low thermal expansion and high tensile elasticity.
