A new procedure of statistical approach characterization of ceramic filament fracture strength by bending tests

A procedure of ceramic filaments characterization has been proposed on the base of bending tests performed on continuous filaments. Using a specific bending device, fracture strength σR and Weibull modulus m related to commonly used tensile test procedure, can be derived from bending results thanks to a simple relation depending on the related Weibull’s modulus. The proposed new procedure is very rapid to perform and allows easy ceramic filaments acceptance testing in industrial contexts. The procedure has been validated by comparing fracture results obtained with the new procedure with those resulting from tensile tests.
