Composite board used as shell

A composite board used as a shell comprises a frame, an opening located in the frame, a middle net fixed in the frame and a shielding layer at least partially shielding the middle net, and the middle net covers the area where the opening is located. The utility model further relates to application of the composite board as a shell on a notebook computer. Compared with the prior art, the structure is provided with the opening located in the frame, and therefore weight reduction is achieved; by arranging the middle net fixed in the frame, the problem that the structural strength is weakened due to the fact that the opening is formed is well solved; in addition, the shielding layer which at least partially shields the middle net is arranged, so that the appearance of the composite board is not influenced. 一种用作壳体的复合板，其包括边框、位于所述边框的内部的开口、固定于所述边框中的中网以及至少部分遮蔽在所述中网上的遮蔽层，所述中网覆盖在所述开口所在的区域。本申请还涉及该复合板在笔记本电脑上作为壳体的应用。相较于现有技术，本申请设有位于边框的内部的开口，从而实现了减重；通过设置固定于所述边框中的中网，较好的弥补了由于设置开口而造成的结构强度减弱的问题；另外，通过设置至少部分遮蔽在所述中网上的遮蔽层，不影响复合板的外观。
