Glass fiber,glass fiber woven fabric, and glass fiber-reinforced resin composition

Abstract

The present invention provides glass fiber that can give a glass fiber woven fabric having an ultra-low dielectric loss tangent and having sufficient handleability. The glass fiber of the present invention comprises a glass composition including SiO2 in a range of 92.50 to 99.99% by mass, TiO2 in a range of 0.01 to 5.00% by mass, and Al2O3 in a range of 0.00 to 2.50% by mass with respect to the total amount of the glass composition, wherein the glass fiber has a tensile fracture stress in a range of 1.0 to 100.0 MPa, and the content S of SiO2, the content T of TiO2, and the tensile fracture stress BS of the glass fiber satisfy the following formula (1): 5.2≤BS×(T/(100−S))2≤33.8 . . .
