摘要

Glass fiber reinforced silica aerogel (GFRSA) was sandwiched between aluminum plates, steel plates, and PMMA (Polymethyl Methacrylate) plates respectively to compose a range of composite structures. And the impact responses of these structures were investigated experimentally using a 7.62 mm ballistic gun. Three sets of comparison experiments were conducted to analyze the effects of plate structures, bullet shapes, and impact velocities. The results showed that GFRSA can significantly improve the impact resistance of composite structures, especially for brittle materials. The destruction models of GFRSA were crushing and splashing of aerogel matrix, fracturing and seperating from aerogel matrix of fiber. And the composite structures showed better impact resistance for flat bullets than sharp ones. In addition, the GFRSA exhibited significant stain rate strengthening effect. Thus the energy absorption and dynamic fracture resistance of composite structures improved under high-speed impact.
