FIELD: chemistry.
SUBSTANCE: invention relates to laminar alumino-polymer composite materials and particularly relates to alumino-fibre glass and articles made therefrom. Laminar alumino-fibre glass contains at least two layers of high-modulus Al-Li alloy with laid in between two layers of reinforced fibre-glass with unidirectional fibres based on epoxy binding agent. Between layers of reinforced fibre glass there is optical fibre with Bragg gratings, laid along reinforcing fibres of fibre glass. One of layers of reinforced fibre-glass has a cutout of trapezoidal shape in zones of rotation of optical fibre.
EFFECT: invention provides creation of laminar composite material, capable of monitoring stress-strain state while maintaining high static strength, high modulus of elasticity, low density, resistance to fatigue destruction and other operational characteristics of crack resistance.
