Embodiment Construction
[0023] The present invention can realize infiltration of glass yarn based on vacuum prepreg equipment, see figure 1 and figure 2 , a glass yarn dipping process, comprising the following steps: step 1, place the rolled glass yarn 1 in a vacuum box 2, the vacuum box 2 is connected with a vacuum pump 3 and a pressure relief valve 4, turn on the vacuum pump 3, make the vacuum box 2 Form a vacuum environment; Step 2, flow the prepared mixture of epoxy resin and curing agent into the vacuum box 2, until the liquid level of the mixture exceeds a certain height of the highest surface of the glass yarn 1; Step 3, continue to the vacuum box 2. The mixed solution is degassed until no large amount of bubbles emerge from the mixed solution; in step 4, the pressure relief valve 4 is opened to allow the outside air to enter the vacuum box 2, and the mixed solution is affected by the unbalanced internal and external air pressure and penetrates into the glass yarn 1. The mixture is soaked in...
