creates mixed private-public researcher’s groups on specific research
projects
The IMAST application fields are Aerospace, Shipbuilding, Automotive,
Railways, Polymeric Electronics, Biomedical, Buildings

STUDY OF REACTION TO FIRE - FIRE RESISTANCE
Carried out Fire Test in CS_GRA
To determinate the
minimum percentage of
oxygen that is required for
self-sustained combustion.
Oxygen Index (LOI-TOI)
Cone Calorimeter test
(ISO 5660)
To analyze the contribute
in terms of heat of the
material in a possible fire
scenario
IMO/LIFT
ASTM E 1321
To study the ignition and
flame propagation
New Small scale burner test
This new experimental set-up has been optimized
during the CS project. It allows to study the resistance
of material to flame penetration

PRO Solicitations from ITD Leader about Research Challenges of
Relevant Importance and Possible Real Future Applications
Long and Intense Interactions with PMI within the Cluster that Give Some Significant Results:
The Universities can Understand Better the Problems of PMI to Innovate Process and Product;
The Universities Have the Possibilities to Convince and Accompany PMI in the Innovation Process.
Possibility to Follow the Development of New Technologies from Low TRL to Higher TRL and see their Application to Large Ground or Flying Demonstrators
Last but Not Least, possibility for Young Researchers (and Students) to be Trained ( and making Publications !!) on Research Themes of Relevant Importance and Very Actual.
Consideration about AIRGREEN Cluster Participation
to JTI “Clean Sky –GRA ITD
21
Consideration about Universities
Participation to JTI “Clean Sky –GRA within
AIRGREEN Cluster
CONTRO
• Need to Co-finance the Research Activities at a Rate of
50% that is Not Easy to Sustain;
• Not so much Interactions with Universities outside those
involved in the Cluster (in Airgreen are All Italian and in
GRA no others Cluster with Universities !!)
• Problems for other Research Teams of the same University,
involved in GRA, that want to Participate to CfP of GRA ITD
• Interactions with others ITDs Research Activities is NULL !!!
22
STARTING POINT
The balance from PRO e CON is in the Green (+) region !!
PROPOSITIONS
All Universities belong to AIRGREEN Cluster, have expressed the intention to be involved in the Clean Sky 2 in the form of Cluster with PMI and Research Centers, but with a more specific technological focus;
In order to overcome the problem of participation of a larger number of research teams , belong to same University, some large Universities think that will be better to participate as “alone” Core Partner to a specific ITD or IADT ;
The alternative approach at the previous point , will be to give the possibility to Universities to be involved in different Clusters of the same ITD o in different ITDs;
Less co-financing and more founds (like that reserved to CfP !!)
More Universities in different Core Partners Cluster;
A little more interaction with other ITDs and IADTs .
