Anotācija Structural Health Monitoring (SHM) is non-destructive testing technique which implements a damage detection and characterization strategy for engineering structures. It is widely applied for rapid condition screening with aim to provide reliable information regarding the integrity of composite structures. Key elements of system functionalities include detection of unanticipated structural damage events, damage location identification and characterization through images, monitoring damage growth and enabling feedback action/alarm mechanism. Fiberglass composite materials are becoming widely utilised in design of wind energy structures because of their performance in terms of high moduli, high corrosion and fatigue resistance, and low weight. Nevertheless the damage assessment by means of ply delamination causing stiffness and strength reduction is required by both industry and certification societies. In current research ultrasonic imaging technique is considered as the most efficient method employed for quality control and damage growth inspection by means of ultrasound B - and C - scans for visualization and direct estimation of the nature, structure and spatial distribution of the defects in GFRP structures. More than fifty impact caused damage GFRP samples with artificial damage have been produced for assessment study. A current research resulted in systemisation of damage and delamination identification means in glass fibre reinforced composite panels.
