Static Fatigue And Tensile Fracture Of Glass Fibres Containing Bubbles

Tensile strength, static fatigue life and related phenomena of glass fibres containing bubbles are presented. The tensile strength distribution follows both a Weibull distribution and double exponential model. The mode, skewness and variance rise with fibre diameter. The static fatigue life does not depend upon the depth of the mirror zone. The cumulative frequency of the static fatigue life suggests a peculiar factor or factors that affect the static fatigue life of glass fibres containing many bubbles. The test endorses the idea that zero stress ageing as well as stress corrosion cause static fatigue in glass fibres.
