Estimation of carrying capacity of aviation engine parts from composite materials

When analyzed phenomena are changed on distances, comparable to the sizes of structural geterogeneity of composite materials, the mathematical models of higher levels than the homogeneous anisotropic body model are used. In this connection the main relationships of the proposed two-component theory of composite materials linear deformability are discussed. On the basis of proposed approach the estimation of the carrying capacity of the blade root is given and the fatigue damage of the cantilever boraluminium beam at bending vibration on natural frequencies is researched.
