TEST ON ADHESIVES
List of adhesive to test:
NUSIL CV-1142-1 silicon adhesive
NUSIL CV-2646 silicon conductive adhesive
EPO-TEK EP-410_LV epoxy conductive adhesive
Dow Corning 3145 RTV silicon adhesive.
Test on TMA (Thermal-Mechanical Analyzer) to determinate
the thermal coefficient of adhesives vs. temperature.
Analysis of the epoxy adhesives on a range of temperature
25°C-100°C, for the silicon adhesives 25°C-250°C.
Mechanical properties: standard test conform to
ASTM D1002-94 for determination of shear modulus and shear
strength of adhesives
Rheology of adhesive: DSC Analysis
Analysis performed to measure the glass and cure temperature,
gel time and the general changing in the properties of
the thermoset adhesives.
a) Thermal test on non-cured adhesives to determine the
general thermal property.
b) Isothermal test on glass transition temperature to
determine the time of gel
c) Thermal ramped test on cured adhesives to analyze the
The range of temperature for epoxy adhesive is 30°C-100°C
and for silicon adhesives is -30°C-250°C.
TEST ON TRAY
Verification of DAQ on the climatic room and performing
thermal tests on aluminum plaques and on Agile`s tray.
Collaboration with INFN of Bari
The DAQ consist in a National Instrument Card and
a Lab Views program created by INFN of Bari for the acquisition
of temperature and deformations in real time on the climatic
Problem is the temperature compensation of strain
gages during the thermal cycle.
Solution is the creation of Whetstone Bridge for every
measurement fixing a gage on a indeformable temperature
