Furthermore, by comparing the cross-section quality of CFRP parts obtained from the proposed integrated manufacturing process with that of drilling, mechanical machining and laser cutting, the integrated manufacturing process is verified to be feasible, cost-effective and capable of avoiding subsequent machining processes of difficult-to-machine CFRPs. 1 Introduction Due to the superior mechanical and physical properties, such as the high specific strength, high specific stiffness, nice thermal stability and vibration absorbing property, outstanding fatigue, wear and corrosion resistance, CFRPs have a broad application prospects in various domains covering the aeronautics, astronautics, civil architecture and transportation industry [1].

Introduction At present ,in large civil aircraft ,The Boeing 777 vertical tail, horizontal tail, rear air-tight box, cabin floor beams, flaps, ailerons, engine cowlings, bay doors, fuselage and wing-covering all use in composite materials.
The large-scale application, in the civil aircraft, of composite materials field design and production provides opportunities on airworthiness and maintenance.
We can know that the inner damages of structure’s production, extension and polymerization is one of the important reason which causes structural failure by analysis of many accidents of engineering structures.
Up to now, there were many researchers who have been studied the composite’s failure mechanism in the application of engineering structures, and making some progress.

In structural engineering applications a sufficient quantity of experimental data to be able to achieve a consistent estimate of nonlinear quantities is seldom available: this applies in particular when the structures are to be tested in situ.
In structural engineering applications, even in inputknown conditions, it is not possible to obtain a large enough number of experimental measurements (as necessary to estimate the statistical quantities of interest), especially when the dynamic tests are conducted in situ.
In some civil structures high non-linearity levels may be directly associated to damage: a technique specifically designed to cope with evolutionary damage would be an important progress for structural diagnostics.
