Polimero eta konpositeen teknologia
Ikerketaren helburu nagusia materialen, prozesamenduen eta diseinuen hurrengo belaunaldirako luzetarako eskala guztietarako oinarri zientifikoa sortzea da, bizkor hazten ari den egitura mailako polimeroaren eta konpositearen esparruaren oinarri izan dadin. Jarduera ikerketako bost esparru nagusiren inguruan antolatuta dago:
1. Diseinu arina (Diseinu kontzeptuala eta materialen hautaketa; Egitura mailako materialak eta egiturak; Material ugariko egiturak).
2. Egitura mailako integritatea (Energia xurgatzen duten materialak eta kaltea toleratzen dutenak; Inpakturako diseinua; Nekerako diseinua; Tribologia).
3. Konpositeen Prozesu Aurreratuak (Autoklabe teknologietatik kanpo; Prozesu termoplastiko likidoak; Meta-zuntzezko laminatuak; NDT fabrikaziorako).
4. Osasunerako biopolimeroak (Material bioxurgagarriak; Protesi iraunkorretarako material biobateragarriak; Mikro-nanoteknologiak).
5. Iraunkortasuna (Birziklapena eta Berreskurapena; zuntz naturalezko konpositeak; iturri berriztagarrietako polimeroak).
Automobilgintzarako, ingeniaritza zibilerako, makina-erremintarako, etxeko aplikazioetarako eta biomekanikarako aplikazioa garatu dituzte.
