Advances in Ceramic Filler Reinforcement of Polymer Composites for Engineering and Industrial Applications

Ceramic filler-reinforced polymer composites have gained considerable attention for their outstanding mechanical, thermal, and chemical properties, making them highly suitable for various industrial applications. This review provides an in-depth overview of fabrication techniques, such as hand lay-up, compression moulding, resin transfer moulding, and additive manufacturing and analyses how processing parameters influence composite performance. The effects of fibre type, ceramic filler content, matrix choice, fibre orientation, and volume fraction on key mechanical properties like tensile, flexural, impact strength, and hardness are critically evaluated. Additionally, physical attributes, including moisture uptake, thermal stability, and resistance to chemical and UV exposure, are discussed. Emphasis is placed on the role of fibre reinforcement in improving the structural strength of epoxy-based composites. Although these materials offer significant benefits, their broader application is limited by issues like high manufacturing costs, the absence of standardised design protocols, and challenges in performance prediction under complex loading. Overcoming these barriers is essential to fully realise the potential of ceramicfilled polymer composites in advanced industrial applications. Major Findings: The study highlights that ceramic filler-reinforced polymer composites exhibit excellent mechanical, thermal, and chemical properties, making them highly suitable for industrial applications. The inclusion of fillers such as SiC, WC, WS₂, and Al₂O₃ significantly enhances strength, stiffness, thermal stability, and moisture resistance. Additionally, optimisation of filler content and manufacturing techniques is crucial for maximising performance while minimising defects such as voids and agglomeration.
