Polymer-matrix composites with reinforcements have received attention due to their light weight and easy processing. However, the existing randomly mixed composites are unable to surpass mechanical properties of their components. We tackled this problem by developing structural hybrid polymer composites. We got inspiration for the design from natural material nacre (seashell), that has exceptional mechanical properties attributed to a hierarchical layered structure comprising polymeric matrices and ceramic 2D-microplatelets. Thus, we propose an eco-friendly fabrication method for the layered structure and microplatelet-reinforced hybrid composite with integrated strength, stiffness, and toughness. We are further producing bulk lamination composites and studying the effect of the 2D-reinforcement on hardness, wear-resistance, and fracture toughness compared to 1D-reinforcements. Our design strategy and simple fabrication method are beneficial to develop engineering composite materials. |
