For airframers, the high specific modulus of Ti MMCs has been the impetus, while engine makers have sought to take advantage of their high specific strength, especially for compressor rotor applications.<\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 14pt;\">During this time, different methods for the production of TMC was applied.<\/span><br \/>\n<span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 14pt;\"> The main procedures are explained with their specifics in the following:<\/span><\/p>\n<hr \/>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 14pt;\"><strong>Foil \u2013 Fiber &#8211; Foil Technology<\/strong><\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 14pt;\">For many years, Ti MMCs were primarily fabricated using foil\/fabric processes.<\/span><\/p>\n<p><span style=\"font-family: Arial, Helvetica, sans-serif; font-size: 14pt;\">High foil costs associated with cross-roll processing of the preferred titanium alloys combined with high fiber costs and low volume demands caused Ti MMCs to only be considered for very high payoff applications.
