Tensile testing of bioinspired composites

Abstract

This research project delves into the mechanical properties of ceramic-reinforced polymer composites fabricated from magnetically assisted slip-casting (MASC). Using the previously studied alumina-based suspensions containing polymer-forming constituents, three distinct types of micro-structures were explored: Unaligned, Horizontal, and Vertical. Tensile testing was employed to evaluate critical properties, including tensile strength, tensile strain at fracture, modulus, and toughness. Despite encountering challenges, such as sample failures and uncertainties in the testing process, a thorough analysis was conducted. Comparative assessments were utilized to illuminate the relative performance of each orientation, offering valuable insights into the material’s behaviour fabricated from MASC with in situ polymerization. The results underscore the importance of micro-structure in bioinspired ceramic-reinforced polymer composites for advanced applications as well as provide guidance on the future work of this study for a deeper understanding.
