Composite materials are increasingly popular. One of the primary composite materials for modern structures is glass fiber reinforced plastic (GFRP), which is commonly used in aviation, modern transport and wind power plants. Scientists of South Ural State University have carried out extensive studies of ballistic properties of GFRP to improve the efficiency of its use.

GFRP is relatively cheap and has high strength. However, practically all well-known results regarding ballistic characteristics of GFRP do not take into account various loads occurring when operating the structures or consider comparatively low-impact loading speeds. At the same time, a more frequently encountered problem is impacts at high speed. The team of scientists from SUSU's Institute of Engineering and Technology have determined ballistic characteristics of glass fiber reinforced plastic under exposure to operational loads at a high speed of impact loading.

"Often, noses of modern trains, which are produced out of composite materials, are exposed to impacts during the train's movement. We have studied the influence of the impact force on a plate made of composite material under the normal operational load. We stretched the sample, creating a strained condition, and...
