Latest Patents

Zok's latest patents include a method of fabricating hybrid ceramic matrix composite laminates. This innovative laminate consists of alternating layers of dense ceramics and fiber-reinforced ceramic matrix composites (CMCs). The approach utilizes strong and stiff ceramics to delay the onset of cracking within the CMC layers. To enhance the laminate's durability, ceramic layers are strategically placed on the outer surfaces to protect against mechanical abrasion, improve thermal conductivity, and inhibit oxygen ingress. The production process involves stacking these layers and hot-pressing them together, allowing for variations in volume fractions and fiber architecture. The reinforcement architecture, whether unidirectional or crossply, significantly affects the tensile and flexural properties of the laminates.
