Udział materiałów kompozytowych w lotnictwie sukcesywnie wzrasta ze względu na wysoką wytrzymałość, sztywność a stosunkowo niską gęstość. W najnowszych samolotach wiodących producentów niemal całe poszycie zostało wykonane z kompozytów polimerowych. Wadą kompozytów polimerowych jest niskie przewodnictwo elektryczne. Zwiększenie przewodnictwa osnowy polimerowej można uzyskać poprzez zastosowanie dodatku proszków metali, co skutkuje zwiększeniem masy kompozytu. Lepszą metodą jest zastosowanie nanorurek węglowych.

Zastosowanie nanorurek węglowych w lotnictwie wiąże się z eliminacją zagrożeń przebić w instalacjach elektrycznych: ekranowanie zakłóceń elektromagnetycznych, ochrona przed wyładowaniami elektrostatycznymi, ochrona przeciw uderzeniom piorunów.

Celem pracy było zwiększenie przewodnictwa elektrycznego żywic epoksydowych oraz poprawa właściwości mechanicznych i termicznych. W pracy stosowano różne metody dyspersji, oraz różne rodzaje nanorurek węglowych modyfikowanych i niemodyfikowanych. Określono wpływ długości nanorurek oraz modyfikacji grupami funkcyjnymi na wzrost przewodności elektrycznej kompozytu. Zbadano właściwości termiczne oraz mechaniczne. Przeprowadzono obserwacje mikroskopowe w celu oceny stopnia dyspersji nanorurek w żywicy.

W pracy uzyskano równomierną dyspersję napełniacza oraz znaczny wzrost przewodności elektrycznej nanokompozytów.

Wstępne prace były finansowane przez firmę Airbus, zainteresowanie przewodzącymi nanokompozytami wyraził również PZL Świdnik.
