- Abstract
Composites consisting of low-molecular weight epoxy resin Epidian 6 and 0- 10 wt. % octakis[(3-glycidylpropyl)dimethylsiloxy]octasilsesquioxane (POSS_OG) cross-linked with triethylenetetramine (Z1) were prepared. The presence of POSS_OG in the composition improved its flow properties and reduced the heat evolved in exothermic cross-linking reaction. The resulting composites containing 1-6 wt. % POSS_OG had significantly increased (by 2-4 times) impact resistance and better flame resistance (increase of LOI by ~ 3.7 points) compared to the non-modified EP 6 resin. By using IR microspectroscopy mapping, an increase in the areas of the bands corresponding to O-Si-O groups was observed for the composites containing I wt. % silsesquioxane.
