Abstract
Glass fibers are often used as reinforcement for composite materials, which makes it necessary for an engineer to know their strength. However, testing a single fiber is technically difficult if not impossible, and we have to use statistical models to describe the strengths and weaknesses of these fibers. To do so, tensile tests are generally done on fiber bundles. The objective of the present Lab work was to deeply understand the failure model of brittle glass fibers, by realizing tensile tests on several bundles to determine Weibull parameters of glass fibers. In this report the following points will be explained: a theory summery about Weibull failure model and the associated parameters; the experimental protocol and data; the results coming from these experiments and the discussion we can have upon those.
