TMC
TMC is a problem solver, especially for aerospace and medical tech and replaces a high number of standard components.
Titanium Matrix Composites (TMC) is a composite made of Ti-Alloy and Si-C fiber. TMC is a problem solver, especially for aerospace and medical tech and replaces a high number of standard components. TMC is very suitable in environments where high forces occur and lightweight components with high strength and stiffness are required.
About
Aerospace engine and airframe designers are constantly seeking lighter weight high strength materials to reduce weight and improve the performance of power plants and aircraft.
Titanium metal matrix composites (Ti MMCs) have offered the promise of significant weight savings since their initial development in the early 1960s, but in the past, their inadequate quality and reproducibility combined with high processing and materials costs have prevented their introduction into production applications.
This project book describes the state-of-the-art for TMC aerospace fabrication and the recent advances in processing which are now leading to high quality, affordable TMC components.
