Embodiment Construction
[0011] The honeycomb panel includes an upper panel layer and a lower panel layer, and a honeycomb core layer is between the upper panel layer and the lower panel layer, and the upper panel layer, the lower panel layer and the honeycomb core layer are all made of glass fiber and hemp fiber Made of raw materials; the production method is: the weight ratio of glass fiber and hemp fiber is: 30% or 40% or 50% or 60% or 70%: 70% or 60% or 50% or 40% or 30%, take Air-laid method, glass fibers and hemp fibers are made into rolls or sheets, and then pressed into sheets by a plate press at a temperature of 180°C-200°C to make upper and lower panels; glass fibers The roll or sheet made of hemp fiber is put into a honeycomb core mold, and the honeycomb core layer is pressed by a press at a temperature of 180 ° C to 200 ° C, and then an adhesive is used on the top and bottom of the honeycomb core layer. Bond the upper panel layer and the lower panel layer, and press it into a honeycomb pan...
