Abstract

The growing demand for advanced materials in small satellite applications, particularly Carbon Fiber Reinforced Polymers (CFRP), underscores the need for innovations in composite components. As epoxy resin forms a key matrix in CFRP, enhancing its properties is crucial for meeting the rigorous demands of space technology. A promising approach involves using functionalized Carbon Nanotubes (CNTs-OH) and Graphene (Gr-COOH) as hybrid fillers. Functional groups improve dispersion, interfacial bonding, and minimize agglomeration within the epoxy matrix, overcoming traditional limitations. Remarkably, these hybrids offer mechanical enhancements comparable to methods like Chemical Vapor Deposition (CVD), while simplifying processing and enabling scalability. Their compatibility with epoxy ensures consistent performance and manufacturability. These functionalized systems represent a significant step toward lightweight, durable, and high-strength materials suitable for extreme environments, aligning with the broader goal of developing advanced CFRP for next-generation small satellites.
