Titanium metal matrix ceramic composite.

Figures 8 10 show the performance of the composite systems in terms of the young s modulus e x and e y in the two mutually orthogonal. At present the most industrially valuable composite materials are polymer matrix composites pmcs ceramic matrix composites cmcs and metal matrix composites mmcs. The ductility is lower than for conventional titanium alloys however recently developed titanium composites show good ductility values. Titanium metal matrix composites ti mmcs have offered the promise of significant weight savings since their initial development in the early 1960s but until recently their inadequate quality and reproducibility combined with high processing and materials costs have prevented their introduction into production applications.

Titanium metal matrix composites tmcs provide an alternative to overcome these shortcomings. The matrix metals included in this study are aluminum titanium magnesium and a superalloy mar m 200 of martin marietta co. Solvent based ceramic matrix composite cmc prepreg high strength. 1650 f 900 c structural applications.

Tmcs have been under significant development and evaluation in the past 30 years for use in aircraft engines and airframe applications. Compared with unreinforced metals mmcs offer higher specific strength and stiffness. Metal matrix composite mmc metal ceramic composites in light metal construction the range of applications for high strength light metal components primarily aluminum but also magnesium and titanium is constantly growing.

Metal matrix composite or mmc for short is a composite material artificially combined with one or more metal or non metal reinforcing phases with metal and its alloys as the matrix. Metal matrix composites findings metal matrix composites mmcs usually con sist of a low density metal such as aluminum or magnesium reinforced with particulate or fibers of a ceramic material such as silicon carbide or graphite. 1 2 mmcs are made by. Unlike other metal matrix composites titanium composites show a much lower wear of the counterpart because the particles like tic or tib show some self lubricating behavior.
