Paragraph starter

The study by Gu et al. (2023) highlights the potential for synergistic improvements in composite materials. Their research demonstrated that interleaving carbon fiber/epoxy composites with BN@ZnO particles significantly enhanced both thermal conductivity (up to 78% increase) and interlaminar fracture toughness (up to 15.4% increase). This suggests that incorporating carefully selected hybrid fillers can lead to multifunctional materials, offering designers a route to improve both thermal management and structural integrity in their designs.
