ВЛИЯНИЕ КРИСТАЛЛОГРАФИЧЕСКОЙ ТЕКСТУРЫ АЛЮМИНИЕВЫХ ЛИСТОВ НА ТРЕЩИНОСТОЙКОСТЬ АЛЮМОСТЕКЛОПЛАСТИКОВ

Abstract

In this paper, the influence of the structure crystallography of aluminum sheets on the crack resistance of metal- polymer composite materials is investigated on the basis of the developed mathematical model. The calculations of the crack resistance of three-layer GLARE have shown the possibility of increasing the resistance to crack opening by us¬ing in their composition aluminum sheets with effective structure crystallography and its coordination with the rein¬forcement direction of the adhesive prepreg with glass fiber. The most favorable ideal crystallographic orientations of aluminum alloys and the direction of fibers laying are determined, which ensure an increase in the fracture toughness of GLARES by more than 15%.
