Flame retardant polypropylene composites were modified with fibers and hybrid combination of natural additives (coconut, wood flour, and walnut shell fibers) with high-strength basalt fiber. The composites were subjected to strength tests and flammability analysis to assess the impact of the fibers on flame retardant material, with the fiber content of 5–20 wt%. Mechanical tests showed the positive effect of fibers on strengthening of polypropylene. The introduction of basalt fibers by 5 and 10 wt% increases the strength by 20 and 40 %, and stiffness by 60 and 160 %, respectively. Natural additives as hybrid reinforcement caused approximately 10 % increase in strength and more than twofold increase in stiffness of the composite materials. Burning behavior assessment showed that the use of natural fibers slows down the process of peak heat release by approximately 20 %. The paper also indicates the positive effect of water and accelerated thermal aging on the mechanical properties of the tested composites. The presented research results point the potential of composites with natural additives as construction materials.

天然添加剂增强的阻燃聚丙烯

阻燃聚丙烯复合材料可以通过纤维改性,以及天然添加剂(椰子,木粉和胡桃壳纤维)与高强度玄武岩纤维的混合组合。对复合材料进行了强度测试和可燃性分析,以评估纤维对阻燃材料的影响,纤维含量为5–20 wt%。力学测试表明,纤维对增强聚丙烯具有积极作用。引入5重量%和10重量%的玄武岩纤维分别使强度增加20%和40%,并且使劲度分别增加60%和160%。天然添加剂作为混合增强材料使复合材料的强度提高了约10%,刚性提高了两倍以上。燃烧行为评估表明,使用天然纤维会使峰值放热过程减慢约20%。本文还指出了水和加速的热老化对测试复合材料的机械性能的积极影响。提出的研究结果指出了天然添加剂作为建筑材料的复合材料的潜力。
