Interpenetrating phase composites (IPCs) have gained attention in the past decade due to their intriguing high temperature structural properties. In this study, an attempt has been made to fabricate TiO2-Cu IPCs and test its structural stability against direct exposure of hydrogen flame. A novel method termed as synergistic sintering has been employed to manufacture TiO2/Cu CM IPC involving sintering of TiO2 and Cu micro particles. Scanning Electron Microscopy and X-ray diffraction has been used to study morphology and phase analysis respectively. Moreover, mechanical properties and thermal properties using hydrogen flame have been investigated. Various concentrations of Cu and TiO2 i.e., TiO2(95 wt%)/Cu(5 wt%), TiO2(90 wt%)/Cu(10 wt%), TiO2(80 wt%)/Cu(20 wt%), and TiO2(50 wt%)/Cu(50 wt%) have been examined against thermos-mechanical properties. It has been observed that increase in Cu wt% improved the resilience as well as reduces thermal cracking. The best results have been demonstrated by TiO2(50 wt%)/Cu(50 wt%), where the recorded compressive strength and elastic modulus was 156.45 MPa and 57 MPa respectively. Moreover, the TiO2(50 wt%)/Cu(50 wt%) IPC did not show any cracking after direct exposure to pure hydrogen (H2) flame.
