In a recent study, we developed ultralow-binder-content (UBC) structural materials based on lunar soil simulant and thermoset binders. In the current research, we investigated thermoplastic binders. Compared to thermosets, advanced thermoplastics could be more UV resistant, more durable, more robust, and recyclable. Our main technology is the compaction self-assembly (CSA). By using only ~4 wt% polyetherketoneketone (PEKK) binder, the thermoplastic-binder UBC composite was stronger than typical steel-reinforced concrete. The CSA operation was separate from the curing process. This study may provide an important in-situ resource utilization method for large-scale construction on Moon.

基于月球土壤模拟物的超低粘合剂含量热塑性复合材料

在最近的一项研究中，我们开发了基于月球土壤模拟物和热固性粘合剂的超低粘合剂含量 (UBC) 结构材料。在当前的研究中，我们研究了热塑性粘合剂。与热固性塑料相比，高级热塑性塑料可以更抗紫外线、更耐用、更坚固且可回收。我们的主要技术是压实自组装（CSA）。通过仅使用约 4 wt% 的聚醚酮酮 (PEKK) 粘合剂，热塑性粘合剂 UBC 复合材料比典型的钢筋混凝土更坚固。CSA 操作与固化过程分开。该研究可能为月球上的大规模建设提供一种重要的原位资源利用方法。
