[0018] The environmentally friendly surfboard described above, wherein: the decorative layer is an artificial painted layer or a printed layer.

[0019] By means of the above technical means, the following effects can be achieved in the present utility model:

[0020] 1. By means of the side protection area formed by repeatedly stacking the two upper RPET fiber cloths and the lower RPET fiber cloth in the present utility model, the bearing capacity of the side of the surfboard of the present utility model is consolidated, that is, it will not break easily even when bearing the beating of the waves, so as to achieve the purpose of high strength and high elastic toughness.

[0021] 2. By using high-density polystyrene foam for the core board in the present utility model, the transmission of the impact force of the waves is reduced, so as to provide excellent elasticity and strength for the surfboard.

[0022] 3. By using RPET fiber cloth to replace glass fiber in the present utility model, the RPET fiber cloth is made from recycled PET bottles through separation, slicing and spinning. Compared with making PET from scratch, the energy consumption of making RPET with recycled materials is 75% less, and at the same time, the carbon dioxide emissions can be reduced by 36%. Moreover, the RPET fiber cloth is very durable, strong and flexible. The RPET material leaves a smaller carbon footprint and is completely recyclable. Description of the Drawings
