Story of Titan Matrix Composites – Episode 4: USP

 

We explained in the past episodes 1 to 3 what is TMC, the history of the delevopment and the technology behind it.

In this episode we focus us on the USP and the features of this very interesting titanium composites.

                                                                                        

 

TMC is very suitable in environments where high forces occur and lightweight components with high strength and stiffness are required.

Our process for the production of reinforced components with SiC fibers offers the best possible properties and a wide variety in production.

The high strength of the fiber leads to the fact, that the mechanical properties of TMC, such as the bending stiffness, are by far surpassing the properties of components made of conventional materials.

                                                                              

 

The following chart represents a pulling test

and compares  TMC made by KTW Systems with high strength steel and titanium:

8,5 x 10-6 12 x 10-6 5 x 10-6 Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature

 

The result is very impressive!

Performance data in a pulling test of TMC compared to:

a) high strength steel:

up to 50% less weight

up to 75% more strenght

up to 10% more stiffness

 

b) Titanium:

up to 15% less weight

up to 115% more strenght

up to 80% more stiffness

 

 

Titan Matrix Composites are the key  for less weight but more stiffness and strength!

In the next episodes we show where  TMC was and is successful implemented and which products and markets can benefit from this technology.
