Manufacturimg and Properties of CMCs containing Ti filler with improved Intra-Matrix Bond

Kurzfassung

In order to improve the performance of CMCs processed via PIP manufacturing, Ti particles were studied as active fillers. As a result they were successfully incorporated in CMCs of different fiber types. Due to the manufacturing process the filler particles were mainly located in the gussets of the CMC, thus leading to a more compact matrix. Based on modified microstructure a considerable increase in mechanical properties could be observed. To strengthen the intra-matrix bond, CMCs were treated with titanium(IV)-diisopropylate before each reinfiltration step. As a result a considerable increase in ILSS and flexural strength was measured.
