  Abstract

When a spacecraft works in low earth orbit, PBO fiber/epoxy resin composite as structural material not only has the poor interfacial properties, but also faces the attack of atomic oxygen (AO). To solve the two drawbacks, a PBO fiber hierarchical reinforcement has been fabricated without degrading the fiber by a mussel-inspired "two-step" method based on dopamine (DA) assistant co-deposition and chemical grafting technologies. The surface wettability, roughness (Ra) and reactivity of the obtained PBO@PDA-Si-GO are increased significantly in comparison with those of untreated one. The reinforcement offered simultaneously remarkable enhancement in interfacial shear strength (IFSS) and AO erosion resistance of the composites, which laid theoretical and experimental foundations for the realization of the structure/function integration design of advanced composites.
