TL;DR: In this paper, a numerical approach was developed to simulate the mechanism of matrix crack deflection at the fiber/matrix interface in brittle matrix composites, and the fracture behavior of a unit cell (microcomposite) consisting of a single fibre surrounded by a cylindrical tube of matrix was studied with the help of a finite element model.
Abstract: This paper describes a numerical approach developed to simulate the mechanism of matrix crack deflection at the fibre/matrix interface in brittle matrix composites. For this purpose, the fracture behaviour of a unit cell (microcomposite) consisting of a single fibre surrounded by a cylindrical tube of matrix was studied with the help of a finite element model. A fracture mechanics approach was used to design a criterion for deflection at the fibre/matrix interface of an annular crack present in the matrix. The analysis of the fracture behaviour of SiC/SiC and SiC/glass ceramics microcomposites shows that the introduction of a low modulus and low toughness interfacial layer at the fibre/matrix interface (e.g. a carbon coating) greatly favours matrix crack deflection at the interphase/fibre interface.

TL;DR: A thin, refractory, intermediate adhesive layer of laminar structure is deposited in oriented fashion on the reinforcing fibers by chemical vapor deposition, this intermediate layer having a greater elongation at break than the matrix and having a thickness of between 0.2 and 3 micrometers.
Abstract: A thin, refractory, intermediate adhesive layer of laminar structure is deposited in oriented fashion on the reinforcing fibers by chemical vapor deposition, this intermediate layer having a greater elongation at break than the matrix and having a thickness of between 0.2 and 3 micrometers; the material forming the intermediate layer can be laminar pyrocarbon or boron nitride; the ceramic matrix is then infiltered, preferably by chemical vapor deposition, inside the pores of the reinforcement.
