Abstract: This study examines thick-walled cylinders made of ceramic matrix composites (CMCs) for biochemical and medical applications. High-performance materials, such as zirconia (ZrO₂)-based and alumina (Al2O₃)-based composites, are identified as optimal for high-stress biomedical applications due to their superior pressure resistance. In contrast, lightweight composites, including boron carbide (B₄C)-based and silicon carbide (SiC)-based materials, are highlighted as cost-effective solutions for low-load medical devices. The research investigates the relationship between wall thickness variation and surface pressure, along with the critical role of stress distribution in material performance. The findings underscore the importance of strategic material selection and design optimisation to improve the safety, efficiency, and durability of medical devices under varying operational conditions.

Keywords: thick-walled cylinder; ceramic matrix composites; CMCs; biochemical applications; medical device performance; stress distribution; material optimisation.
