Microscopic thermal characterization of C/C-SiC composites (2001)
Jumel, J., Lepoutre, F., Frieß, M., Krenkel, W., Neuer, G.
The C/C-SiC composites are made of several micro-components, whose properties are often not characterized precisely. Such a lack of knowledge makes difficult the use of multi-scale numerical...
