The fracture behavior of alumina and carbon fibers was investigated by using the loop test. The fracture surfaces of these fibers indicated a typical pattern containing a line shape, which appeared on the compression side of alumina fibers and on the tension side of carbon fibers. These fracture morphologies are interpreted as being locations of crack initiation (tension side in alumina and compression side in carbon), propagation following by bend-breaking. The loop test proved to be a useful and simple method to identify the fracture process.
