FIELD: aviation.
SUBSTANCE: invention relates to composite materials for use in aircraft design and relates to method and device for increasing fire resistance and fracture toughness of composite structure. Composite structure with increased fire resistance and viscosity of destruction contains the most internal layer and fire-resistant layer containing the first additive to increase resistance of the specified structure to ignition, wherein fire-resistant layer is inner layer of composite structure and contains second additive to increase structure destruction viscosity.
EFFECT: invention improves fire-resistance and preserves the viscosity of destruction of the composite structure without affecting the order of its production and weight.
