Description

Composite material sheet manufacturing apparatus using thermoplastic resin {MANUFACTURING APPARATUS FOR COMPOSITE SHEET USING THERMOPLASTIC RESIN}

The present invention relates to a sheet manufacturing apparatus, and more particularly, to a composite material sheet manufacturing apparatus using a thermoplastic resin having an extruder for extruding a thermoplastic resin and molding a composite material sheet using the extruded resin.

In general, a composite material is a material in which one or more materials are mixed and used. As an example of such a material, a composite material in which a resin and a fiber are mixed and impregnated is representative.

Such a composite material may have different properties of strength and hardness depending on the type of resin and fiber to be mixed, the length of the fiber, and the mixing method. there is.

In a conventional composite material, fibers are manufactured through a pultrusion process. Conventionally, the fibers are immersed in a storage tank in which the resin is stored and the resin is wetted while passing through, and the fibers are molded into a certain shape while passing through the guide frame.

The fiber soaked in resin passing through the guide frame is manufactured in the form of a hollow pipe, and in the process of passing through the impregnation mold, heat and pressure are applied, and the fiber is impregnated with the resin and hardened. The composite resin manufactured through this process is cut to a desired length.

Here, in the prior art, a large pressure is required to impregnate the fiber into the resin, which is a factor in increasing the manufacturing cost.

In addition, conventionally, since the mold, especially the core mold forming the inner hollow, is made of a metal material, it is impossible to change the dimension such as thickness when the thickness deviation of the resin occurs or when the specification of the product is changed, so the rate of dimensional change cannot be accommodated. Due to the temperature change of the product production, the defect rate is becoming a factor that increases.

In addition, in the prior art, in the manufacturing process of composite resin, the work was performed using high pressure on the mold, and there was a technical limitation in that the product had to be produced at a low speed to prevent deformation of the mold, which caused overall productivity to deteriorate. becoming a factor.

In addition, as conventional composite materials are continuously produced by drawing fibers, only composite materials in which the fibers are arranged in a unidirectional direction can be manufactured, and thus the composite materials may be split in the direction in which the fibers are arranged.

In addition, conventional composite materials are manufactured by impregnating fibers with one type of resin, and thus, it is difficult to implement various physical properties of the composite material.
