Description du projet/ Project
Description
Composite materials used to make space
structures are subjected to space
environments where the temperature can
fluctuate between -170 oC to + 150 oC,
where different types of failure may
occur. The project studies this problem.
Objectifs/ Objectives
1. Understanding the behavior of cyanate
ester/carbon laminates and sandwich
structures under thermo-cycling.
Identifying the main influence
parameters and building models that
correlate different influence parameters
(amplitude of thermal cycle,
heating/cooling rate, vacuum, layup
sequence, etc), microcrack density and
mechanical properties.
2. Investigate the interface between the
fiber and resin in order to establish
failure mechanism and assess the
influence of different surface
treatments
3. Developing epoxy and cyanate resins
with low CTE and high crack resistance
based on inorganic nanoparticles and
CNTs. Investigation the behavior of the
nanocomposites under thermo-cycling.
4. Development of a conductive
structural adhesives that meets the
requirements of high shear strength and
good thermocycling resistance
5. Guideline development for optimal
design of composites with enhanced
resistance in space environment.
