This study evaluates the effects of the manufacturing process and fiber reinforcement on low-velocity impact response of the recently developed PVA fiber-reinforced alkali-activated stone wool composites. To this end, reinforced and unreinforced specimens manufactured by hot-pressing were compared with those oven curing. The results revealed a similar impact response for the hot-pressed composite produced at 120 °C for 3 h and its counterpart cured at ambient pressure at 60 °C oven for 24 h. Furthermore, fiber reinforcement significantly improves the impact resistance of the hot-pressed composites showing about a 50% increase in peak load and a 40% reduction in penetration compared to the unreinforced materials. In view of the development of the hot-pressed composites and potential applications, accurate predictive models are of extremely importance, hence the material mechanical behavior was here simulated by adopting the concrete damage plasticity model to predict the low-velocity impact response of both unreinforced and reinforced materials and successfully verified for the scaling-up purpose.

这项研究评估了制造工艺和纤维增强对最近开发的PVA纤维增强的碱活化石棉复合材料的低速冲击响应的影响。为此，将通过热压制成的增强和未增强样品与烘箱固化进行了比较。结果表明，对于在120°C下生产3个小时的热压复合材料，其对应的冲击响应相似，其对应物在60°C的烘箱中于环境压力下固化24 h。此外，纤维增强显着改善了热压复合材料的抗冲击性，与未增强材料相比，峰值载荷提高了约50％，渗透率降低了40％。鉴于热压复合材料的发展及其潜在的应用，
