Description

Factors affecting the tensile strength of glass fibers are reviewed. Fracture and fatigue degradation, the principal causes of glass fiber failure, depend on surface flaws, tensile strength, and moisture. Abrasion protection coatings can preserve fiber strength and are applied as thin or thick coatings, depending on cable design. Tensile strength of coated fibers can be plotted against failure probability on a Weilbull plot. A small percent elongation will produce a large unrelieved tensile stress.
