This paper describes the hybridization of basalt and carbon fibres in polyamide 6 by injection moulding method and the analyses of the mechanical, morphological, fire, and smoke properties of the obtained materials. The content of basalt/carbon fibres in hybrid composites amounted to 5/5 wt%, 7/7 wt%, and 10/10 wt%. The addition of fibres resulted in an increase in mechanical properties of the examined materials, was reflected by the threefold increase of Young modulus for the composites containing 10/10 wt% of fibres. To investigate the aging, the samples were stored in distilled water for 1, 7, 14, 100, and 210 days. After 210 days, a significant decrease in mechanical properties was observed. Interestingly, the addition of fibres caused a 50% reduction in stiffness, whereas, in the case of neat polyamide 6, the decrease was about 78%. Additionally, the addition of fibres reduced water sorption. With the increasing fibre load, the decrease in the maximum average rate of heat emission was observed. In the case of composites containing 10 wt% of basalt fibres and 10 wt% of carbon fibres, it amounted to 207 kW/m2 and was lower by approx. 37% in comparison to the unmodified polymer.

基于聚酰胺 6 与玄武岩/碳纤维的混合复合材料的机械、火灾和烟雾行为

本文介绍了玄武岩和碳纤维在聚酰胺 6 中通过注射成型方法的杂化，并分析了所得材料的力学、形态、防火和烟雾性能。混合复合材料中玄武岩/碳纤维的含量分别为 5/5 wt%、7/7 wt% 和 10/10 wt%。纤维的添加导致所检测材料的机械性能增加，这反映为含有 10/10 wt% 纤维的复合材料的杨氏模量增加了三倍。为了研究老化，将样品在蒸馏水中储存 1、7、14、100 和 210 天。210 天后，观察到机械性能显着下降。有趣的是，添加纤维导致刚度降低了 50%，而在纯聚酰胺 6 的情况下，降低了约 78%。此外，添加纤维减少了吸水。随着纤维负载的增加，观察到最大平均放热率降低。在含有 10 wt% 玄武岩纤维和 10 wt% 碳纤维的复合材料的情况下，它达到 207 kW/m2 并且低了大约 20 kW/m2。与未改性聚合物相比为 37%。
