Abstract

The results of static tests of specimens that were made from carbon fiber reinforced plastic with a honeycomb filler according to acoustic emission (AE) and strain-gauge measurement are given. When using the two-lag method, the stable locations of AE signals are obtained, which indicates the development of fatigue cracks. The dependences between the main informative parameters of AE signals and features of the destruction of a material are analyzed. According to strain-gauge measurement data, the values of the failure stress are determined.
