Abstract:

The main purpose of the present investigation was to characterize the behavior of S-glass fibers at quasi-static strain-rates. It has been established that fiber strength decreases with increasing strain-rate. The experimental results demonstrate that Weibull distribution can adequately represent fiber strength distribution for quasi-static strain-rates. For the type of glass tested, strength was observed to be maximum at or near the room temperature 75deg F. The strength dependence on strain-rate is greatest at the room temperature. At higher or lower temperatures the dependence on strain-rate is not so marked. Tests were also performed to determine the elastic modulus at various temperatures and strain-rates. The elastic modulus increses with both an increase in strain-rate and a decrease in temperature. Author, modified-PL.
