FIELD: technological processes.
SUBSTANCE: invention relates to high-temperature ceramic materials and can be used in designing structural composites with fragile components. Crack-resistant fibrous ceramic composites contain ceramic dies and oxide fibres. Unidirectional reinforcement of die with fibres having flat parallel axes of face fibres connected in pairs at faces with strength lower than the value of fibre and matrix strength is used. Weak surfaces of fibre boundaries are used as stoppers on the way of crack propagation.
EFFECT: invention provides higher crack-resistance of composite materials while preserving stability of structure at high temperatures.
