The paper presents the concept of mechanoacoustic testing of degradation processes of ceramic electrotechnical materials. Samples of small dimensions are subjected to slowly increasing compressive loading with simultaneous recording of acoustic emission descriptors. The process is continued to the destruction or is stopped at various stages of degradation of the material structure. Microscopic analysis of samples enables determining the effects of stress action.

W pracy została przedstawiona koncepcja mechaniczno-akustycznych badan procesów degradacji ceramicznych tworzyw elektrotechnicznych. Małogabarytowe próbki poddawane sa wolno narastajacemu obciazeniu sciskajacemu z jednoczesna rejestracja deskryptorów emisji akustycznej. Proces prowadzi sie do zniszczenia lub zatrzymuje na różnych etapach degradacji struktury. Analiza mikroskopowa próbek pozwala określić efekty oddziaływania naprężeń.
