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:
| Characteristics | Titanium Alloy | Steel- high strength | TMC by KTW Systems | Remarks |
| Density in g/cm3 | 4,6 | 7,8 | 4,0 | |
| Strength in Mpa | 1.100 | 1.700 | 2.200 | 20-30o C |
| Strength at 600o C in Mpa | 650 | 800 | 1.400 | high temperature applications |
| Stiffness in Gpa | 115 | 190 | 210 | |
| Elongation in % | 15 | 6 | 1,3 | |
| Thermal expansionin Ko-1 | 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.
