Obiectivul principal al proiectului este dezvoltarea de noi materiale
hibride compozite cu matrice termoplasta dopate cu fibre si nanoparticule disperse
cu proprietati speciale (pentru industria chimică, petrochimică sau
auto precum şi pentru producerea de produse noi sau imbunatatite).
Conceptul proiectului are la baza posibilitatea de proiecta si dezvolta
materiale nanocompozite pe baza de polipropilena sau poliamida si umpluturi
anorganice precum nanoparticule, nanotuburi, whiskersuri si fibre care duc la
maximizarea proprietatilor, in special din punct de vedere al compatibilitatii
dintre faze, al stabilitatii termice si foto si a proprietatilor mecanice. De
asemenea, vor fi obţinute materiale laminate pe baza de polipropilena si
poliamida continand fibre si tesatura de sticla si de carbon cu proprietati
eterogene, scopul final fiind obtinerea de materiale multifunctionale pentru
aplicatii complexe (materiale compozite usoare cu performante tribologice si
termale de suprafata asemanatoare sau similare metalelor si proprietati
mecanice remarcabile in interiorul materialului. Pentru o mai buan
compatibilitate intre faze vor fi testate diversi agenti de cuplare atat a
matricii cat si a umpluturii.
The main
objective of the project is the development of new hybrid composite materials
with thermoplastic matrices doped with fibres and disperse nanofillings in
order to obtain materials with special purposes (for chemical, petrochemical
and auto industry as well as for producing new or improved consumer goods. The
concept of the project is based on the possibility to design and develop some
nanocomposite materials based on polypropylene-PP and polyamide and inorganic
fillers such as nanoparticles, nanotubes, whiskers and fibers which lead to
maximized properties especially from the point of view of the compatibility of
the phases, thermal and photo-stability and mechanical properties. Also PP and
polyamide based laminated materials will be obtained containing glass and
carbon fibers and texture with heterogenic spatial properties, the purpose
being that to obtain multifunctional materials for complex applications
(lightweight composite materials with tribologycal and thermal performance
close or similar to the metals on the surface and remarkable mechanical
properties into their inner layers. To assure a better compatibilization
between the phases, different coupling agents will be tested, having in view
both matrix and fillers modifications.
