ABSTRACT
Fibre reinforced titanium alloy composites were first developed about 20 years ago, and have since made substantial progress towards a mature engineering material. The fibre and its protective coating has been refined and optimized. Testing methods have been developed and mechanical properties have been extensively characterized. In broad terms, titanium metal matrix composites (MMCs) have been shown to have an attractive combination of properties, and good stability and durability for extended service. A number of demonstration parts have been manufactured, and tested successfully under service conditions. Cost remains a major concern, and much current effort is aimed at developing cost effective manufacturing methods. This article describes recent progress at DERA, and discusses options for future commercialization of titanium MMCs.
