FIELD: aviation.;SUBSTANCE: tape prepreg for fabrication of thermal-protective coating of the pressure restraint layer of the housing contains mutually fastened pieces of band extensible in the tangential direction and impregnated with phenolic binder. The prepreg is implemented in the form of multilayered band in each layer of which the pieces of its bands are mutually fastened end-to-end with the shift of these joints located in neighbouring layers, with reference to each other. The band layers are mutually fastened in the points located in zigzag fashion along longitudinal axis of the band.;EFFECT: improvement of quality of fabrication of thermal-protective coating due to optimisation of structure and the design and process layout of fabrication of the band prepreg with the increased thermal erosion resistance in combination with improved heat-insulating properties and smaller thickness.;2 cl, 1 dwg
