几十年来，开发能够增强航天器中聚合物和复合材料结构的制造方法的努力导致了大量的研究和创新。然而，热稳定性，固有的材料应力和各向异性的基板性能提出了重大的挑战，并抑制了在极端空间环境下使用先前提出的解决方案。在这里，我们通过开发一种定制设计的等离子体增强交联聚（对二甲苯）：类金刚石碳超晶格材料来克服这些问题，该材料能够增强与软聚合物和复合材料的机械耦合，从而可以应用于大型3D工程结构。开发的超晶格结构与基材形成一个整体部分，并导致空间合格的碳纤维增强聚合物具有10-20倍的抗开裂性，而不影响尺寸稳定结构的刚度。这项创新为下一代先进的超稳定复合材料铺平了道路，用于即将到来的光学和雷达仪器空间计划以及先进的工程应用。等离子体增强交联聚（对二甲苯）（PECLP）：沉积DLC超晶格与经典聚（对二甲苯）PECLP相比，PECLP的弹性模量高10倍：DLC屏障为复合材料提供了近零应力条件增强复合材料具有机械完整性和更高的抗裂性航空航天工程;工程材料;材料物理
The endeavors to develop manufacturing methods that can enhance polymer and composite structures in spacecraft have led to much research and innovation over many decades. However, the thermal stability, intrinsic material stress, and anisotropic substrate properties pose significant challenges and inhibit the use of previously proposed solutions under extreme space environment. Here, we overcome these issues by developing a custom-designed, plasma-enhanced cross-linked poly(p-xylylene):diamond-like carbon superlattice material that enables enhanced mechanical coupling with the soft polymeric and composite materials, which in turn can be applied to large 3D engineering structures. The superlattice structure developed forms an integral part with the substrate and results in a space qualifiable carbon-fiber-reinforced polymer featuring 10–20 times greater resistance to cracking without affecting the stiffness of dimensionally stable structures. This innovation paves the way for the next generation of advanced ultra-stable composites for upcoming optical and radar instrument space programs and advanced engineering applications. Plasma-enhanced cross-linked poly(p-xylylene) (PECLP):DLC superlattice is deposited PECLP exhibits ∼10 times higher elastic modulus compared to classic poly(p-xylylene) PECLP:DLC barrier provides near-zero stress conditions for use on composites Enhanced composites exhibit mechanical integrity and improved crack resistivity Aerospace Engineering; Engineering materials; Materials physics
