Description
Summary:An experimental analysis of characteristics of a carbon-ceramic composite material based on a braided preform in a plane stress state was carried out. The technical limits of strength and elastic characteristics of the material are determined. Tests of tubular specimens in a complex stress state allowed us to obtain the data necessary for the constrction of the failure criterion. The possibilities of using various failure criteria of the composite are investigated. The contours of the surface of the strength of the material in the space of stresses at the intersection of its coordinate planes are built.
