SANDWICH STRUCTURES

Sandwich structures are specific type of a laminated composite, comprising two thin, stiff and strong faces separated by a thick, light and weaker core. In comparison to simple laminates, sandwiches have higher stiffness, better insulation properties and lower weight.

Kompozitní materiály jsou laminátové konstrukce ze dvou nebo více složek. Tvrdší, tužší a pevnější výztuž představují tkaniny uhlíkové, aramidové, skelné a jejich hybridy, aluminizované a diolenové tkaniny, rovingy, sendvičové a další materiály. Funkci pojiva zastávají pryskyřice a doplňkové epoxidové systémy.

Společnost GRM Systems s.r.o. (hlavní žadatel) a společnost Foller s.r.o. (partner projektu zapojený do realizace) společně realizují projekt Moderní kompozitní matrice (CZ.01.1.02/0.0/0.0/15_019/0005093), jehož cílem je vývoj kompozitních systémů s výrazným zlepšením odolnosti kompozitních profilů na bázi nejmodernějších reaktoplastických systémů matric. Na tento projekt je poskytována finanční podpora od Evropské unie (OPPIK).
