Interpenetrating phase metal/ceramic composites (IPC) offer an optimum combination of strength, stiffness, wear resistance, and thermal properties. An infrared camera is a tool used to detect infrared (IR) radiation emitted from a specimen. Ceramics and polymers are two main candidate materials for membranes, where the majority has been made of polymeric materials, due to the low cost, easy processing, and tunability in pore configurations. Typical properties of ceramics. @article{osti_1422589, title = {Ceramic composites: A review of toughening mechanisms and demonstration of micropillar compression for interface property extraction}, author = {Kabel, Joey and Hosemann, Peter and Zayachuk, Yevhen and Armstrong, David E. Introduction. Composite resins are less brittle than ceramics but have greater wear at the edges so may not last as long as a bonded ceramic restoration. More than 40 years ago, ceramic bearings were introduced due. Some studies used MoSi 2 as a reinforcing phase in ceramic-matrix composites for high-temperature applications, as in the work of Grohsmeyer et al.
