Abstract

Samples of 1.6 mm thick fiberglass plastic sheet with different matrix curing modes were loaded in the elastic region according to the cantilever bending scheme. Both extreme and average values of frequencies and amplitudes of emission signals were recorded, besides, the duration of acoustic emission signals was recorded too. The criteria for evaluating the degree of matrix curing were the value of its microhardness. The acoustic emission signals recorded on various samples were analyzed with the matrix microhardness values taken into account, after which the corresponding dependences were plotted.
