Abstract
Tests for evaluating delayed fracture of an E-glass fiber were conducted under water environment. Loaded E-glass fibers were immersed in purified water, and time-to-fracture was measured. Since the delayed fracture was confirmed under the water, the moisture was the only environmental factor for the delayed fracture. The relationship between the chemical reaction and the fiber strength was evaluated for estimating moisture-absorption effect on the delayed fracture. The E-glass fiber surface was observed by XPS and AFM. These observations showed that roughness on the glass surface increased due to the moisture-absorption. Furthemore the fiber-bundle strength decreased with increasing immersion time. The results of these observations indicated that microscopic cracks accelerated the delayed fracture under the water. It is concluded that the delayed fracture of the E-glass fiber occurred by microscopic crack growth caused by moisture-absorption on the glass surface.
