The present invention relates to an apparatus for manufacturing a prepreg composite sheet, and more specifically, to a process of expanding the width of a reinforced fiber material, and a fabric sheet made of a plurality of reinforced fiber materials with expanded widths and a resin film laminated thereto. It relates to a prepreg composite sheet manufacturing device that can automate the process of manufacturing a composite sheet by integrating it and the process of laminating a protective film on both sides of the composite sheet.

In general, prepreg is an intermediate composite material made by infiltrating liquid synthetic resin such as epoxy resin into fiber reinforcement such as carbon fiber or glass fiber. When such prepreg is subjected to heat and pressure in the final part mold, its mechanical and thermal properties change. Excellent composite parts are manufactured.

These prepregs are manufactured in a roll wound around a paper tube while attached to the release paper. The sheet-like prepreg is separated from the release paper, and the separated prepregs are stacked in multiple layers and the resin is cured while heating and pressing to produce a molded product. I do it.

Looking at the system for manufacturing these prepregs, the manufacturing system varies depending on the type of matrix resin.

In other words, looking at the manufacturing system of prepreg that applies a thermoplastic resin as a matrix resin, reinforcing fibers (yarn or sheets) wound on a roller are prepared, and the sizing agent (epoxy-based) contained in the reinforcing fibers is desizing. In the process of supplying and moving the desoldered reinforcing fiber, thermoplastic resin film, and release paper to be stacked, it is heated and then compressed at an appropriate pressure so that the thermoplastic resin is impregnated into the reinforcing fiber, and the release paper is attached to one side of the reinforcing fiber. Manufacturing is completed by wrapping the prepared prepreg in a roll shape around the paper tube.

In addition, looking at the prepreg manufacturing system that applies a thermosetting resin as a matrix resin, reinforcing fibers (yarn, tow) wound on a roller are prepared, the reinforcing fibers are passed through a thermosetting resin contained in a container, and the thermosetting resin is impregnated into the reinforcing fibers. Then, the thermosetting resin of the reinforcing fiber is squeezed (removed) while passing between a pair of rollers, the squeezed reinforcing fiber is passed through an oven, the thermosetting resin of the reinforcing fiber is dried, and then one or both sides of the dried reinforcing fiber are dried. Attach release paper to the paper tube and wrap it in a roll to complete production.

It may include a lower central bar (23c) that integrally connects them.

At this time, as the plurality of upper heating rods 22 are located between a pair of adjacent lower heating rods, the fiber fabric 1 entering the interior of the second body frame passes between the upper and lower heating rods. In the process, the upper and lower surfaces come into contact with them and are heated and compressed by the upper and lower heating rods that generate heat when power is applied, so the thickness of the reinforcing fibers (F) forming the textile fabric (1) becomes thinner. A spraying process is performed to widen the width.

Meanwhile, at the entrance of the second body frame 21 where the fiber fabric 1 supplied from the first body frame 11 enters, heat such as infrared light generated when power is applied is transmitted to one side of the fiber fabric. It may include a fabric preheating unit (20a) that preheats the textile fabric.

In addition, both left and right ends of the first heater support having the first infrared heater are connected to the rod ends of the left and right pair of fabric preheating cylinder members 24c fixed to the inner upper part of the left and right pair of support plates 24a. Since the gap between the first infrared heater and the textile fabric can be narrowed or widened by the vertical movement of the cylinder member for preheating the fabric, the process of preheating the textile fabric by heating it while the heating temperature of the first infrared heater is constant is carried out. You can control it.

Accordingly, in the process of entering and passing between the upper and lower heating sections, the fiber fabric is exposed to infrared light transmitted from the first infrared heater of the fabric preheating section before performing a spraying process that thins the thickness of the reinforcing fiber and increases its width. By preheating, the work efficiency and productivity of the spraying process can be increased by shortening the time for heating the textile fabric by the upper and lower heating rods.

It can be provided.

Accordingly, the driving force of the actuator causes the pair of left and right inner upper plates including the upper heating rod and the upper heating bar to reciprocate in the horizontal direction perpendicular to the pass line with respect to the lower heating rod, thereby contacting the upper and lower heating rods in one direction. By increasing the friction between the upper and lower surfaces of the passing textile fabric, spraying efficiency for the reinforcing fibers that make up the textile fabric can be increased.

Additionally, the spraying unit 20 may include a lower moving unit 20c that reciprocates the lower heating rod up and down in a direction toward the upper heating rod.

You can be guided round trip.

By moving the vertical screw axis up and down to move the lower heating rod so that the vertical gap between the upper and lower heating rods is widened or narrowed, the upper and lower surfaces of the fiber fabric passing in one direction in contact with the upper and lower heating rods Spraying efficiency can be improved by increasing the transmitted compressive force.

Accordingly, by rotating the handle, the pair of left and right inner lower plates including the lower connecting rod and lower insulating bar are reciprocated up and down in a vertical direction perpendicular to the pass line with respect to the upper heating rod, thereby contacting the upper and lower heating rods in one direction. Spraying efficiency for the reinforcing fibers that make up the textile fabric can be increased by increasing the friction between the upper and lower surfaces of the textile fabric passing through.
