Abstract
本发明公开了一种仿生互穿TC4‑PE的卫星天线基座的制备方法，涉及航空航天复合材料及星载结构技术领域；该方法包括：构建具有双手性螺旋拓扑结构的三维点阵骨架模型；通过增材制造技术以TC4钛合金制备所述三维点阵骨架；将聚乙烯填充至所述三维点阵骨架的孔隙中，并使其与TC4钛合金形成互穿相复合结构；本发明通过双手性螺旋拓扑设计实现了多向稳定变形与渐进式承载，降低了初始峰值应力并提升了变形稳定性；通过压力辅助真空熔融浸渍实现了聚乙烯的高填充率互穿，提高了比吸能与阻尼减振性能。所得基座兼具轻量化、高承载、抗冲击减振及耐空间环境等多功能协同特性，为卫星天线长期在轨稳定运行提供了可靠支撑。
