Abstract

Abstract The article presents the methodology and results of strength tests with simultaneous registration of acoustic emission. The subject of the research were glass fibre-reinforced plastics (GFRP) made by hand lamination. The obtained results allows to identify the stresses characteristic of the individual stages of the material failure process. These results can be the basis for determining the safe scope of application of the mentioned materials, especially helpful at the stage of designing ship and aircraft structures. The analysis of the test results allows to determine the safe level of stresses not exceeding about 70 MPa.
