Abstract

This study focusses on the experimental and numerical investigation of the continuous carbon fiber-reinforced silicon carbide (SiC), and silicon nitride (Si3N4) matrix composites. A testing procedure has been designed to study the Charpy impact testing system. The dynamic elastic-plastic fracture toughness (JdSiC=11.88kJ/m2 and JdSi3N4=1.77kJ/m2) as well as the dynamic stress intensity factors (kdSiC=36.88 MPaem2and JdSi3N4=22.03 MPaem2) have been evaluated. Further on, a good agreement between finite element results and experimental findings was found.
