About us We
are a group of material scientists from various Italian Institutes strictly
involved for several years in preparing and testing ceramic matrix
composites by different techniques and for various purposes (brakes,
thermostructural materials as fusion reactor components, engine or
turbine components, tubes, aerospace, etc).

|
Our skills
Composites Processing
Intelligent process control for composite materials fabrication
including organic matrix and ceramic matrix composites processes by
various techniques.
|
|
 |
Fibrous
Preform Creation
2D Fibrous preforms are created cutting and adequately
stacking carbon or SiC fabrics.
|
|
 |
CVI
Thin ceramic layers are deposited onto fibers in order
to improve CMC mechanical properties and to protect fibers. CVI layers
allow:
- crack defection,
- debonding at the fiber/matrix interface,
- fiber bridging,
- fiber pullout.
|
|
 |
CPF
Inert fillers are forced to fill the fibrous preform
for a better material densification. |
|
 |
PIP
Fibrous preforms are impregnated with a pre-ceramic
polymer which is converted via heat treatment in order to create the
ceramic matrix of the composite. |
|
 |
Reaction
Bonding
The composite matrix can react with a molten metal to
be converted in a different ceramic material and/or to fill residual
porosity. |
|
Composites Characterization
Analysis of properties of matrix resins, reinforcement fibers and
composites.
|
|
|
Physical characterization
Materials density, porosity measurement. |
|
 |
Mechanical characterization
Flexural strength and Young modulus measurement.
|
|
|
Optical and SEM microscopy
