Abstract [en]

In this paper, we report the development of a glass fiber commingled composite (GFCC) based on a nanoclay-doped polyamide 6 (PA6) and the evaluation of its combustion behavior. The preparation of the composite has involved several steps. Firstly the nanoclay was dispersed in the PA6 matrix. Then, the produced compound was spun in filaments and commingled with glass fibers. Finally, the laminate preform was consolidated. In order to evaluate the effect of the nanoclay on the combustion behavior of the GFCC, samples based on the neat PA6 were produced as well. The results show that the effect of the nanocomposite matrix was a significant improvement regarding heat release when a continuous external heat flux is applied (cone calorimeter), whereas in the presence of the glass fibers the positive effect is more pronounced in tests where a small flame is induced to ignite the vertically oriented sample (UL94 vertical burning test). This is connected to the different mechanisms by which the nanoclay affects the combustion behavior, whether in the presence of glass fibers or not.
