[0011] The advantages and positive effects of the utility model are:

[0012] 1. Compared with the floor made of original wood, the present application supplements the existing high molecular material and carbon fiber synthetic material by the characteristics of the existing wood and its performance in different temperature and humidity, which can effectively adapt to a larger humidity span and temperature span use environment while retaining the wood structure of the contact surface, and ensure the long-term working strength of the board.

[0013] 2. The high-strength oak impregnation layer, wood-plastic layer and PVC composite layer are compounded by the compounded wet carbon fiber nylon cloth interlayer, which has high compression resistance and low moisture absorption characteristics. BRIEF DESCRIPTION OF DRAWINGS
