Abstract: In the manufacturing method of fluoro based polymer composite boards of the invention, which provides a fast process and high efficiency, a suitable amount of water soluble organic solvent is added to a fluoro based polymer suspension during the process of mixing ceramic powder and/or glass fiber to the fluoro based polymer suspension in order to improve the coagulation of the fluoro based polymer and ceramic powder, and to reduce the gelling time. During the process of mixing ceramic powder and/or glass fiber, the fluoro based polymer suspension and the organic solvent, a suitable amount of water can be added to control the ratio between the water and the organic solvent obtained from the mixture. The gelling time of the mixture can thus be reduced. By controlling the ratio between the water and the organic solvent obtained from the mixture, there is still enough time to allow homogeneous mixing after the gelling speed is increased.
