Example Embodiment
[0026] A method for preparing double-sided flat glass fiber reinforced plastic plates for laboratory testing,
[0027] First heat the glass work surface to between 25-35℃,
[0028] Lay glass fiber cloth on the surface of the glass work surface;
[0029] Place a pressure plate with holes on the fiberglass cloth;
[0030] Place a diversion net on the small hole area of the perforated pressure plate;
[0031] Place the glue injection base on the diversion net;
[0032] Laying air felt and covering it on the fiberglass cloth;
[0033] Place the winding tube on the glass work surface and cover it with air felt, and connect one end of the winding tube to the exhaust pipe;
[0034] Lay the vacuum film and cover the winding tube, air felt, fiberglass cloth, perforated pressure plate, diversion net and glue injection base. The edge of the vacuum film is sealed with a sealing tape and fixed on the glass work surface;
[0035] The other end of the suction pipe connected with the winding pipe is conn...
