Evaluation of the physicochemical properties of boron-aluminum composite by the method of acoustic emission

Conclusion

With the aid of the described method processes occurring in composites at the early stages of loading can be judged. The method yields a comparative characteristic of the strength of the bond at interfaces and makes it possible to judge initial defectiveness of the composite and residual thermal stress due to different production technologies of the composite. Moreover, the method makes it possible to differentiate between the kinds of defect of the composite. For a more detailed study of the properties of composites it is necessary to carry out experiments with composites obtained by different technologies. For a better understanding of the physics of the process it is necessary to obtain the spectral components of the signals, the amplitude distribution in time, and also to use additional research methods.
