Resin has better liquidity, so the dipping time is longer; if possible, the gridding cloth should not be dense. Using coupling agent before dipping may have a better boding effect.
The viscosity of the resin should be moderate; The surface modifying agent of the glass fiber cloth and the compatibility of resin should be better; Resin solution mixing should be sufficient to ensure uniform distribution of resin solution; The temperature should be moderate (too high temperature will let resin curing ahead of time and too low molecular inadequate activity); The pressure should be moderate (so as to exhaust air from the glass fiber cloth while not damaging the glass cloth). It mainly is about the above points.
