Description

Technical Field [0001] The present invention relates to an RTM mold apparatus for molding a body part,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an RTM compound mold apparatus for molding a body part, and more particularly, to an RTM compound mold apparatus for molding a body part, To an RTM composite mold apparatus for molding a body part.

A composite material refers to a material having two or more materials having different compositions or shapes and having an effective function.

Composite materials include fibers, particles, lamina, and matrix. Composite materials composed of these elements are generally layered composites, particle reinforced composites, fibers Reinforced composite materials, and the like.

Traditionally, composite materials are polymer composite materials, which are used in the same sense as fiber-reinforced plastics and fiber reinforced composite materials.

On the other hand, it is recognized that composite materials have a somewhat improved meaning than fiber reinforced plastics (FRP). In particular, composite materials using high-performance reinforcing fibers such as carbon fiber are classified into high-performance composite materials.

For reference, raw materials for fiber-reinforced plastics and composites can be divided into reinforcing fibers and matrix materials. The reinforcing material of the composite material mainly uses continuous fibers.

Historically, fiberglass is the oldest reinforced fiber, but the frequency and importance of its use can be attributed to carbon fiber (graphite fiber or carbon fiber). In addition, aramid fibers typified by Kevlar are widely used, and boron fibers and ceramic fibers such as silicon carbide, which are less frequently used, are also used.

If the reinforcing fiber is a load-bearing element, the necessity of the base material is absolutely necessary in order to achieve a structural shape by fixing each of these fibers in place. Also, when the shear load is applied, the mechanical property of the base material is very important because it supports the load, and it has a decisive influence on the progress of fracture. Also, because most of the fibers are stable to external elements (heat, chemicals, etc.), resistance of the matrix to these external elements is often important.

Epoxy resins are used in the latest composite materials as base materials, and unsaturated polyester resins are still a large part of general composites. Phenol, polyimide resin and aluminum Etc., and in recent years, thermoplastic resins have also been widely used.

Due to the efficient combination of materials, composites which can have high weight-ratio strength and stiffness as well as various excellent material properties can be used as substitutes for existing materials by effectively utilizing their characteristics, and furthermore play a synergistic role in technological innovation It is especially noteworthy that it is.

The use of composites has important advantages that lead to performance and productivity. For example, the flexibility of design allows composites to control the properties of composites, making them the only material that can realize new design concepts. Therefore, it is possible to make a wide variety of plastic resin composite materials, metal composite materials, ceramic composite materials and carbon / carbon composite materials, which have been developed so far, in aerospace, automobile, sports, industrial machinery, medical equipment, military supplies, Has been applied.

Meanwhile, there are various methods of molding a composite material. Examples of a molding method of a composite material based on a polymer material include an autoclave molding method, a vacuum bag molding method, a compression molding method, Filament winding, SMC molding method or BMC molding method, RTM molding method (Resin transfer molding), Pultrusion molding method, hot press molding method, Vacuum infiltration casting, liquid metal pressing and so on are available.

The utilization of the carbon fiber composite material as described above is gradually increasing. For example, in recent years, as the specific gravity of electric automobile batteries has gradually increased, body parts have been changed from old steel to carbon fiber composite materials, and other body parts are also being changed to carbon fiber composite materials.

The carbon fiber composite material is widely used as a substitute material for steel because it can provide light weight and high strength (securing stability) of body parts including body parts, as well as provide electromagnetic wave and heat resistance performance.

In order to manufacture a vehicle body part using such a carbon fiber composite material, RTM (resin transfer molding), that is, resin injection molding, which is one of the molding methods described above, may be used. In this case, RTM A molding compound mold can be used exclusively.

RTM molding is a resin injecting method using a closed type, and a method is used in which a shape is formed, and then a resin, that is, an epoxy and an economizing resin, is injected into a mold and hardened. It is known that such RTM molding is suitable for mass production of body parts, and can provide a clean finish and high dimensional accuracy.

On the other hand, as mentioned for a while, the mold to which the carbon fiber composite material is applied needs to be impregnated with the resin because the epoxy and the economizing resin are injected into the mold.

In this case, in order to impregnate the carbon fiber well, a vacuum condition due to an external environment, that is, a clamp structure is essential. In the case of an existing mold apparatus, due to the structural limit, the resin is not impregnated well, It is difficult to improve the molding quality because it is somewhat inefficient. Therefore, there is a need for a new concept of RTM composite mold apparatus for molding body parts.
