Investigation of cutting-induced damage in CMC bend bars

MATEC Web of Conferences, 2015
Ceramic matrix composites (“CMC”) with a strong fibre-matrix interface can be made damage-tolerant by introducing a highly porous matrix. Such composites typically have only a low interlaminar shear strength, which can potentially promote damage when ...
