Professor Naslain and his colleagues designed and experimentally validated the
chemical vapor infiltration (CVI) process, a technique to manufacture large parts from
C/SiC and
SiC/SiC composites for
aerospace applications. In 1977, he and his team were probably the first to manufacture a ceramic matric composite. Both the Société Européenne de Propulsion (now Safran Ceramics) in Bordeaux and the
DuPont Company in Wilmington, Delaware (now General Electric), employ this approach. Dr. Naslain's other research interests include synthesis and crystal chemistry of alkali metal borides, crystal chemistry of boron-rich borides, and interfacial phenomena in metal-matrix or ceramic-matrix composites. ==Awards and honours==
