Abstract
Combining high strength, excellent toughness, and outstanding impact resistance still remain challenges in architecture ceramics limited by their inherent brittleness. Inspired by the natural structure of shells, the multilayered ceramic/resin/fabric composite was fabricated via surface hydroxylation followed by a simple hot press process. It was found that the optimized ceramic/epoxy resin/Kevlar fabric composite showed up to 44.89%, 52.49%, 753.77%, and 148.33% improvements to 84.53 ± 5.0 MPa, 2.76 ± 0.04 MPa·m1/2, 53.19 ± 0.80 J·m1/2 and 1.49 ± 0.10 J, respectively in the strength, toughness, fracture work, and impact energy compared to traditional ceramic. This unique combination of properties in this composite was ascribed to the layered design, elastic contents, and appropriate bonding state, corresponding to several strengthening and toughening mechanisms, such as crack deflection, interfacial debonding, and fiber pull-out. These properties, including typical step-like fracture and non-catastrophic failure, advancing the applications of traditional ceramics in high-performance composites manufacturers.
