Purpose: The aim of the work was to find relationship between the ultrasonic wave velocity and the strenght and Young's module in a glass-polyester composite. Design/methodology/approach: The experiments have been performed in three distinct phases. During the first phase, typical glass-polyester composite was ageing to get different mechanical properties. In the second phase, strength and ultrasonic properties of composite was testing. In the last of phases we compare changes of properties. Findings: The experimental results showed relationship between velocity of ultrasonic wave and strength and Young's module. Research limitations/implications: In those applications, in which polymer structural composites were subjected to a heat and mechanical load, it is essential to test the strength characteristics of the composites in the use of non-destructive methods. That enables contemporaneous status check of the structure and makes it possible to replace the bivalent evaluation scale (good - bad) with an incessantly gradable strength degradation scale for a material. Practical implications: The results of the investigation have shown possibility of using ultrasonic method to diagnosis of strength changes in composites. This method allowed to test working parts of machines or buildings, without destruction. Originality/value: The results of the investigations allow to confirm, that ultrasonics can be used to non-destructive testing of the strength and Young's modulus changes.
