Flexible Cover Board Nanomaterial Buffer Layer Impact Resistance

The patent replaces rigid glass with a flexible cover board comprising a flexible substrate and multiple functional layers including buffer layers and hardened layers. This flexible structure enables bending properties while maintaining protective functions through the composite layer design rather than using traditional rigid glass shells.

The patent employs a composite structure with multiple layers including flexible substrate, buffer layers, and hardened layers. Each layer contributes specific properties: the flexible substrate provides bendability, the buffer layers absorb impact energy, and the hardened layers provide scratch resistance. This composite material approach resolves the contradiction between rigidity for protection and flexibility for bending.

The patent incorporates buffer layers with through-holes filled with nanomaterials before the hardened layers. These buffer layers are positioned to absorb and dissipate impact energy before it reaches the brittle hardened layers, providing beforehand cushioning that prevents sudden breaking while maintaining structural strength.

The patent uses through-holes filled with nanomaterials within the buffer layers, creating a porous structure that enhances impact absorption. The nanomaterial-filled pores provide energy dissipation pathways that improve reliability under external impacts while maintaining the overall structural integrity.
