Description
The Low Earth Orbit (LEO) environment presents a tough challenge for materials, exposing them to atomic oxygen, ultraviolet radiation, thermal cycling, and high vacuum conditions. These harsh conditions can wear down traditional spacecraft material (Finckenor, 2018; Grossman & Gouzman, 2003). As a result, there has been a growing interest in lightweight, functional alternatives, especially polymer nanocomposites that offer better resistance to these environmental factors.
This study focuses on poly(2,5-benzimidazole) (ABPBI) and graphene oxide (GO), molybdenum disulphide (MoS₂) and Ti₃C₂ MXene ABPBI composites. The specific focus of this work is the mechanical response of these composites under conditions relevant to LEO.
This study considers experimental techniques to evaluate and compare the mechanical behaviour of the composites. Tensile testing is performed to determine key properties such as stiffness, strength, and elongation, enabling direct comparison between the different nanofiller systems.
The results highlight the influence of nanofiller type on the mechanical performance of ABPBI-based composites and provide insight into their suitability for use in demanding space environments.
