CERAMIC AND POLYMERIC COMPOSITES
For higher product and process efficiency
The development of new multi-functional composites enhances product and process efficiency and opens big innovation opportunities in several industrial fields: construction, mechanics, transportation, energy and chemistry.
Skills and know-how residing in the MITAI Laboratory – Ravenna Technopole Faenza Headquarters allow to manufacture long fibre-reinforced ceramic matrix composites (CMC) using all main available techniques.
Such materials manifest remarkable performance advantages thanks to the combination of properties typical of ceramics with advantages given by the long fibre reinforcement (e.g. reduction of fragile behaviour).
ADVANTAGES OF CERAMICS
+ ADVANTAGES OF LONG FIBRES REINFORCEMENT
high mechanical reliability
= CONVENIENT COMBINATION
Several other typologies of composites are being studied at MITAI Technopole, apart from long fibre-reinforced ceramic matrix composites which are mainly used for their thermo-structural function. In particular particulate-reinforced CMC, industrial refractory materials and ceramic-loaded polymers with various structural and functional purposes, such as tribological properties or durability.
Long fibre-reinforced CMC are designed and manufactured thanks to several technologies and equipment owned by ENEA Faenza that are shared with MITAI Technopole for industry-oriented research:
> the biggest CVI plant (Chemical Vapour Infiltration) at a national level (working diameter 300 mm, working height 700 mm) suitable for the production of many kinds of composites, such as: SiCfibres/SiCmatrix ,Cfibres/SiCmatrixandCfibres/Cmatrix in which the inorganic matrix is produced from gaseous precursor compounds
> PIP plant (Polymer Impregnation Pyrolysis, size equivalent to the CVI plant, working diameter 400 mm, working length 720 mm), for the production of different kinds of long fibre-reinforced CMC, also in combination with aforementioned CVI, in which the inorganic matrix is produced from polymeric precursor compounds
> CBC-related expertise (Chemically Bonded Ceramic), thanks to the skills gained by CNR-ISTEC on aluminosilicate matrices (geopolymers), and by ENEA Faenza on phosphate matrices, both usable for the cost-efficient production of fire-resistant CMC. Long-fibre reinforcement can be added, by employing a wide variety of fibres (e.g. glass, basalt, carbon, as well as the more expensive oxide and non-oxide ceramic fibres)
> spray coating - spray pyrolysis - dip-coating (sol-gel and slurry coating processed) plants, with the possibility of controlling the humidity, for the application of antioxidant and anticorrosion coatings. The developed ceramic composites can be tested at our labs to determine chemical-physical, microstructural and thermo-mechanical properties
MITAI also offers the opportunity to perform the mechanical characterisation of long fibre-reinforced polymer matrix composites (PMC) and to apply coating by means of EPD (Electrophoretic Deposition).

CMC-related technologies are relevant to different fields:
> in the field of building materials, it is possible to produce CMC with structural reinforcement purposes serving at the same time as insulating layers, without the need of introducing flammable or low-durability insulating materials.
> in the industrial field, CMC allow to improve process efficiency thanks to their high thermo-structural properties, guaranteeing at the same time corrosion, abrasion and erosion-resistance.
> in the automotive, aeronautics e aerospace fields, the introduction of CMC allows to contribute to the structural lightening of also those parts that cannot be made of polymeric composites (notably not high temperature-resistant) because of their proximity to engines or exhaust pipes.
