Abstract: The present invention provides a bottom plate of a resin tank for three-dimensional printing, which is manufactured through the following steps: substrate surface roughening step: treating the upper surface of a transparent substrate by using a plasma, or disposing a composite film on the upper surface of the transparent substrate to form a non-smooth surface structure having pores; substrate surface modification step: sequentially performing an activation treatment and a fluorination treatment on the upper surface of the transparent substrate; and stabilizer filling step: applying a stabilizer to the upper surface of the transparent substrate to fill the stabilizer penetrates into the pores on the upper surface of the transparent substrate. The low surface energy film reduces the adhesion of the hardened photosensitive material, and the stabilizer maintains the structure of the low surface energy film, so that the resin tank bottom plate has both oleophobic and hydrophobic properties.

Abstract: A fiber reinforced plastic (FRP) molding system in which FRP material, having stacked prepregs, is molded to manufacture an arc-shaped FRP component. The FRP molding system comprises inner and outer jig plates, a partial pressing device, and transfer devices. The jig plates are arc-shaped members having outer and inner surfaces that respectively fit with inner and outer surface shapes of the FRP component.

The partial pressing device intermittently compresses a portion of the integrated jig plate in a radial direction orthogonal to an arc of the FRP component so that the FRP component is partially molded. The transfer devices intermittently move the compressed portion of the integrated jig plate by the partial pressing device. By repeating the partial pressing and the transport, the entire integrated jig plate is compressed to form the FRP component.
