Modern aerospace engineering applies polymer composite materials extensively. With the purpose of developing a technique for quality control of composite materials we investigated an acoustic emission of fibreglass reinforced plastics, organic fibre composite, carbon fibre reinforced plastics and glue bondings at loading. With usage of outcomes obtained on samples, the method of acoustic emission is developed for the prediction of a burst pressure of a starting membrane made of fibreglass plastics and the strength of fibreglass pylons glued to a fibreglass shell. The quality criterion for the membrane and the gluing of pylons is designed. On the basis of acoustic-emission property research of fibreglass reinforced plastics, organic fibre composite, and carbon fibre reinforced composite and also glue bondings the criteria of strength are determined for specimens of these materials. One of these criteria, namely, he sum of AE hits during exposure under the load is trusted to be the basis of an engineering technique for definition of quality of membranes from fibreglass plastics and glue bonding of pylons.
