Peel resistance of geopolymer sandwich with foam and honeycomb cores

Popis výsledku v původním jazyce

Geopolymers are amorphous aluminosilicate materials which combine low temperature, polymer-like processing with high temperature stability and fire resistibility without toxic smoke generation. This work compares a conventional (glass/ phenolic resin) sandwich structure with a new sandwich structure (carbon/ geopolymer resin). In addition three different manufacturing methods (hot bonding, cold bonding and curing/bonding in single operation) using four different adhesives were compared. Several types of organic and inorganic adhesives were used to bond the laminate skin to foam and honeycomb cores. The peel strength was two times higher than the reference glass/phenolic prepreg sandwich. In the group of honeycomb core specimens, the best results showed Resbond® 989 bonded specimens. The peel strength was three times higher than the reference sandwich. Fracture surfaces were evaluated considering the peel strength and load-displacement curves. This research can establish new fire resistible sandwich materials to be used in aerospace constructions.
