Chemical vapor deposition (CVD) diamond films are suitable as protective coatings on cutting tools for machining advanced composite materials, owing to their extremely high hardness, favorable wear resistance, low friction coefficient and high thermal conductivity.
In the case of machining the composite materials, the protective effects of the diamond films are mainly provided by the extremely high hardness withstanding the abrasive attack, and low frictional coefficient helping to reduce polymers stick to the tools [7].

Delamination is a known mode of failure for composite materials.
In laminated materials, repeated cyclic stresses or impact loads can cause layers to separate, with significant loss of mechanical strength.
Early and reliable detection of such defects is essential for utilization of full potential of these materials.

Introduction The topological optimization is a mathematical method,The basic idea is to turn the seek of the optimal topological of structure problem into the design to explore the best material distribution problems in a given area.
The basic idea of Cistern stents is the introduction of a density variable material which the hypothetical density values between [0, 1].
If the target is the minimum of structural deformation, considering material volume constraints (quality constraint) and structure balance, so the mathematical model of the topological optimization is: For, makes: (1) , , (2) In the formulation，C is Structure deformation energy,F is Load vector, K is Stiffness matrix, D is Displacement vector, V is With the material of structure volume,V0 is volume of design domain of structure, V1 is Less than Xmin the material volume of the unit density,f is Percentage of Surplus materials, Xmin is the lower limit of the relative density of Unit, Xmax is the upper limit of the relative density of Unit.
