- Abstract
- The results of strength tests of CFRP T800 samples with a stress concentrator in the form of hole with diameter of 12 mm with simultaneous effect of static and thermal loads are given. The dependences of the main informative parameters of the acoustic emission (AE) signals on the static load and temperature are analyzed. With a static load of P = 30 kN effect of temperature on the destruction of the matrix and fiber was investigated using fractography. In addition, the relationship between the change in structure of carbon-filled plastic and main informative parameters of AE signals is estimated.
