Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fiber reinforced plastic material and a method of manufacturing the same, and more particularly, to a structure of a continuous fiber reinforced extruded plastic material and a method of manufacturing the same.

[0002]

2. Description of the Related Art In the prior art, there have been several types of methods for producing a fiber-reinforced plastic material, for example, as described below. Prior art 1 The procedure for manufacturing the fiber reinforced plastic material is as follows.
The first profile (first) is formed by a pultrusion (also called pultrusion) technique.
After the profile was formed, the second profile was formed by coating the first profile with a thermoplastic material using an extruder.

Prior art 2 It can be produced as a fiber-reinforced plastic material by combining with an extruder to sufficiently impregnate reinforcing fibers in an impregnating device. The impregnating device is split mold (s
This is a die hole that constitutes one curved path by combining a split casing and a spreader unit, and a filament (roving roving or strand s depending on the type).
(also referred to as “trans.”) can be sufficiently impregnated with the resin by utilizing the time when the resin is inside the die hole, and the resin is supplied by joining an extruder to the impregnating device.
The molten resin was extruded into the die hole to impregnate the fibers.

Prior art 3 It is to adopt a special die head, provide side feed holes for a plurality of filaments, and supply the filaments after the die head is connected to the extruder. Then, a thermoplastic cylindrical material containing a reinforcing filament was extruded. Prior Art 4 It is that the reinforcing fiber is drawn through the inside of the crosshead die of the extruder and sufficiently impregnated the fiber by utilizing the high pressure of the extruded resin, and extruded together after impregnation. Upon cooling, a fiber reinforced thermoset material was formed.

[0005]

However, in the prior art 1, the best bondability can be obtained only by appropriately controlling the temperature in the coating process, and the reinforced plastic material formed by this method is the first type. Since the profile is a continuous fiber impregnated with a thermosetting resin, it cannot be heated and processed again, and furthermore, a foamed product cannot be manufactured, and also shaving and nailing Secondary processing such as welding could not be performed.

In the prior art 2, in the case of an amorphous polymer (amorphous polymer), the resin cannot be sufficiently impregnated in the manufacturing process, and the fiber is subjected to the inside of the curved path. Large and thick plates could not be manufactured due to the high resistance and the tendency for fiber breakage. Moreover, in this structure, there was no foamable material and the specific gravity was relatively large. In addition, the fibers could be arranged only in a single direction.

In the prior art 3, since the fiber content of the reinforced plastic material of the present invention cannot be greatly increased, the reinforcing efficiency is limited, and most of the fibers have too large a bending angle to break the fibers. And the fiber arrangement was not tight in only one direction, did not exhibit appropriate bending rigidity and bending strength, and was not foamable, so that the specific gravity was large.

In the prior art 4, since the amorphous polymer cannot be sufficiently impregnated in this manufacturing process and a backflow phenomenon may occur when the fiber enters the crosshead die, It could only be applied to reinforced plastics in one direction.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a structure of a continuous fiber reinforced extruded plastic material which is excellent in workability and has increased bending strength and bending rigidity, and a method for producing the same. I do.

[0010]

The continuous fiber reinforced extruded plastic material according to the present invention comprises at least one plastic base material and two continuous resin reinforcing fibers impregnated with a resin. It is a reinforced extruded plastic material composed of 1 plastic base material and 2 continuous fibers impregnated with resin. Then, the continuous reinforcing fibers are symmetrically positioned inside the plastic base material, or are symmetrically joined to upper and lower surfaces of the plastic base material to form a sandwich structure. It has at least one continuous reinforcing fiber inside, or a fiber reinforced structure in combination with one of these three types of fiber reinforced structures. According to the structure of the extrusion die head, reinforced extruded plastic material of a specific shape such as flat plate, angle or rod is manufactured.

Further, one of the methods for producing a continuous fiber reinforced extruded plastic material according to the present invention is to provide an extruder, and the extruder extrudes a plastic base material having a specific shape according to the structure of an extrusion die head. Molded, a tape-like reinforcing fiber pre-impregnated with a thermoplastic or thermosetting resin is integrally joined with the plastic substrate extruded from the die head of the extruder by heating and molded by a fixed die. After being cooled, it is a continuous fiber reinforced extruded plastic material. Another manufacturing method is to adhere a reinforcing fiber pre-impregnated with a thermoplastic or thermosetting resin to an extruded plastic material by an adhesive method. In the above two methods, one layer on the surface of the extruded plastic material is covered with a coating layer as necessary, thereby increasing the flexural strength and flexural rigidity of the reinforced plastic material and increasing the appearance.

To explain the operation of the present invention, the present invention discloses a reinforcing material structure and a manufacturing method of a continuous fiber reinforced extruded plastic material, wherein the extruded plastic material is foamable or non-foamable. The reinforcing continuous fiber is a unidirectional, cross-shaped or non-woven fiber mat, so that the reinforcing fiber can be selected more flexibly, and a heat treatment is first performed in the impregnation device. Fully impregnated with plastic or thermosetting resin to form resin impregnated fiber material, and when extruded with extruded plastic material, impregnated resin acts as adhesive at interface Things. When using a foamed extruded plastic material, the continuous fiber reinforced plastic material has properties such as drilling, shaving, nailing, and sawing, and as a plastic material and continuous fiber for reinforcement, Since any of them can be made of a thermoplastic material, it can be molded and processed by secondary heating and can be crushed and recycled.
