将下面这段话进行学术化润色：由多层石墨烯片叠加而成的石墨烯小块作为增强体随机均匀地分散在基质材料中且石墨烯含量沿着厚度方向逐层呈梯度或均匀变化。它与板壳结构相结合可以更好地应用于工程中因此对其各种力学行为的研究是非常有必要的

The graphene small blocks, composed of multiple layers of graphene sheets, serve as reinforcing agents that are randomly and uniformly dispersed within the matrix material. The graphene content exhibits a gradient or uniform variation along the thickness direction. When combined with the plate-shell structure, it can be better applied in engineering applications. Therefore, it is necessary to study its various mechanical behaviors in depth.
