With the aid of the latest fiber optic sensing technology parameters in the cure process of ther- mosetting resin-matrix composite, such as temperature, viscosity,void and residual stress, can be monitored entirely and *** this paper, experiment results of viscosity measurement in composite cure process in autoclave using fiber optic sensors are presented. Based on the sensed information, a computer program is utilized to control the cure process. With this technology, the cure process becomes more apparent and controllable, which will greatly improve the cured products and reduce the cost.

＜正＞ Although using fiber optic refractive index sensor to monitor the resin cure process has long been known as a kind of novel and promising method, there is no farther report of the investigation on the in-situ monitoring of composite manufacture process. In this presentation, a kind of fiber optic refractive index sensor is developed and a portable instrument for the optic emission, signal receiving and interrogation are integrated to meet the requirements of on-site application. With it the cure process of resin and fiber reinforced prepreg is monitored. Tests of resin cure process monitoring are carried out with both resin that should be cured under room temperature and resin that should be cured under high temperature. The results of tests with resin cure under temperature are compared with the results of Michelson interferometer tests under similar circumstance, which are in good consistency. Tests are also carried out during composite manufacture, in which the fiber optic refractive index sensors are embedded in prepreg during the cure process. It is proved with the method the key information of the cure process can be extracted out during the process and be used in on-line intelligent control. In conclusion, this technique can be used not only in the establishment of the cure routine but also the in-situ monitoring and control of the composite manufacture process.

The technology of Intelligent cure operation is set forth according to developing tendency of smart material and structure. Intelligent-system-based tool was developed in order to operate the autoclave cure of a fiber reinforced thermosetting matrix composite laminate in an optimal manner. The objective function is comforts for minimizing the total cure time, uniforming the temperature distribution, controling exothermal and minimizing the process-induced residual stresses in the laminate. Data is analyzed on-line to determine the trends in real-time. The results from application of this overall strategy for the curing of composites are presented.

Truss core sandwich panels reinforced by carbon fibers were assembled with bonded laminate facesheets and carbon fiber reinforced truss cores. The top and bottom facesheets were interconnected with truss cores. Both ends of the truss cores were embedded into four layers of top and bottom facesheets. The mechanical properties of truss core sandwich panels were then investigated under out-of-plane and in-plane compression loadings to reveal the failure mechanisms of sandwich panels. Experimental results indicated that the mechanical behavior of sandwich structure under in-plane loading is dominated by the buckling and debonding of facesheets.

The dynamic behavior of two parallel symmetric cracks in a piezoelectricstrip under harmonic anti-plane shear waves is studied using the Schmidt method for permeable cracksuface conditions. The cracks are parallel to the edge of the strip. By means of the Fouriertransform, the problem can be solved with the help of two pairs of dual integral equations. Theseequations are solved using the schmidt method. The results show that the stress and the electricdisplacement intensity factors depend on the geometry of the cracks, the frequency of incidentwaves, the distance between cracks and the thickness of the strip. It is also found that theelectric displacement intensity factors for the permeable crack surface conditions are much smallerthan those for the impermeable crack surface conditions.
