【 摘 要 】

Structures made of multilayered composite materials are designed to work under different types of external loads, both static and dynamic. Often, under dynamic impact, material failure occurs in the inner layers of the material and is not noticeable during external visual inspection. Untimely detection of such damage may lead to a complete failure of the structure. Therefore, the substantial problem in the control of objects made of laminated composite materials is the determination of various characteristics of external dynamic impact, which will allow to estimate the danger of an impact and localize the damage in the structure. The object of this study is a multilayered plate made of fiberglass composite, subjected to impact loads of different energy. This paper investigates material failure after an impact load and the sensitivity of a network of piezoelectric sensors to external dynamic loading.
