step 1, uniformly mixing 100 parts by mass of liquid unsaturated polyester resin, 2-3 parts by mass of an initiator, 2-6 parts by mass of a release agent and 10-15 parts by mass of other auxiliary agents in a mixer to form a dipping liquid, and placing the dipping liquid into a dipping tank;
step 2, discharging the fiber cloth from the unreeling roller at a speed of 2 meters per minute, and pressing the fiber cloth into a gum dipping tank through a driving roller to dip the fiber cloth, so that the gum dipping liquid in the gum dipping tank dips the two sides of the fiber cloth and the gaps inside the fiber cloth;
step 3, guiding the dipped fiber cloth into a pultrusion die through a guide roller, heating the fiber cloth to 150-160 ℃ in the pultrusion die, initiating a crosslinking reaction to cure the unsaturated polyester resin through an initiator under a high temperature condition, and shaping in a die cavity, wherein the curing time is 1-3 minutes; wherein the pultrusion die is provided with a die cavity matched with the cross section of the mounting plate;
step 4, delivering the shaped fiber cloth resin composite material into a circulating water cooling tank for cooling, wherein the water temperature is controlled to be 10-40 ℃, and the cooling time is 1-3 minutes; the cooled section bar is pulled into cutting equipment by a pull roll and is cut into sections according to the length of the mounting plate; processing through holes with the required number and shape at the required positions on the mounting plate; forming a mounting plate body;
and 5, assembling the deformation detection mechanism on the mounting plate main body.
