Abstract

Vacuum hot pressing has been used for the development of titanium metal matrix composites using foil-fiber-foil method, and in particular the effect of fiber arrangements on densification behavior has been investigated by employing a thermo-acoustic emission technique. The explicit representation of fiber arrangements is modeled within the finite element framework, and is fully coupled with deformation behavior. Good agreement between computed and experimental data of consolidation process has been achieved. Further experimental measurements have shown that the AE detection covers not only the evolutions of porosity but the micro-material failures as well. As shown by the results, it is apparent that the levels of consolidation strongly depend on the shape of fiber distributions so as to the rectangular arrangement produces much higher levels of strain distribution than triangular, and thus it needs much more time to proceed to the full dense state.
