PART MADE FROM OXIDE/OXIDE COMPOSITE MATERIAL FOR THREE-DIMENSIONAL REINFORCING AND METHOD FOR MANUFACTURE OF SAME Russian patent published in 2019 - IPC C04B35/80 

FIELD: instrument engineering.

SUBSTANCE: invention relates to an oxide/oxide composite part that contains fiber reinforcement formed by a plurality of layers of warp threads and weft threads, interconnected by means of three-dimensional weaving, while the spaces between the reinforcing threads are filled with a matrix of refractory oxide. Said part is characterized in that the fibrous reinforcement has a fabric weave selected from the following weaves: interlock, multi-layer linen, multi-layer satin and multi-layer twill, and the thread count in the warp and weft, ranging from 4 to 20 threads/cm. Further, the volume content of fibers in fiber reinforcement ranges from 40 to 51 %.

EFFECT: after the matrix is formed inside the structure, the blocks of the matrix have dimensions smaller than fivefold maximum knotting of the threads, which helps prevent the appearance of cracks in the final material of the part.
