在本文中，我们报道了基于纳米粘土掺杂聚酰胺6（PA6）的玻璃纤维混合复合材料（GFCC）的开发及其燃烧反应的评估。复合材料的制备包括几个步骤。首先，将纳米粘土分散在PA6基体中。然后，将产生的化合物纺成长丝并与连续玻璃纤维混合。最后，层压预制件被固结。还生产了基于纯 PA6 的参考样品。结果，虽然众所周知，在存在一定量的连续纤维的情况下，材料的行为主要由纤维本身驱动（例如机械、热、传导等），但粘土的影响很有趣，特别是在可燃性测试（UL94 垂直燃烧测试）中，总燃烧时间从 227 秒变为 146 秒。
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 fire reaction. The preparation of the composite comprised several steps. Firstly, the nanoclay was dispersed in the PA6 matrix. Then, the produced compound was spun in filaments and commingled with continuous glass fibers. Finally, the laminate preform was consolidated. Reference samples based on the neat PA6 were produced as well. As a results, although it is well known that, in the presence of a relevant amount of continuous fibers, the behavior of the material is mainly driven by the fibers themselves (e.g. mechanical, thermal, conductive, and so on), the effect of the clay was interesting, especially in flammability test (UL94 vertical burning test), where the total burning time passes from 227 s to 146 s.
