and step four, after the glass fiber cloth and the chopped strand mat pasted in the step three are solidified, polishing the surfaces of the glass fiber cloth and the chopped strand mat to be flat, and thus obtaining the glass fiber reinforced plastic dustbin.
7. The glass fiber reinforced plastic dustbin with chassis according to claim 6, wherein the pasting of the plurality of layers of glass fiber cloth and chopped strand mat in the third step is to paste a layer of chopped strand mat on the resin substrate layer, then paste 5-8 layers of glass fiber cloth on the chopped strand mat, and then paste a layer of chopped strand mat on the glass fiber cloth.
