Hypersonic Research Team
Since 2022, the objective of this research is to provide an understanding of the properties of ceramic matrix composite (CMC) materials used in hypersonic vehicles using high powered lasers. A main focus is so that they can be operated for an extended period of time and have high reliability monitored under a laboratory constructed thermal imaging and IR/RF transparent sensor. The micromachining, sensor development, and related material studies will be carried out using high powered lasers so that temperatures over 2000C can be easily achieved and the measurement data can validate current-day models. The focus of these studies are on the COI Ceramic Inc. CMC S400N samples (IM7 carbon fiber in an amorphous SiNC matrix) provided by the Northrop Grumman Corporation, but the method can be applied to other material systems.
Laser Micromachining
Window hole micromachined using 1064 nm laser for the insertion of a sapphire window
Laser Brazing
Laser brazing process using a 1070 nm infrared laser, heating range from 100 to 1700C
Optical Fiber Integration
A silica-based optical fiber is being integrated into the S400N sample using a potting cement called Zircon, the same fiber is then being tested for optical viability
Material Analysis
