業性を低下させている。 Conventionally, in FRP molding by pultrusion and filament winding, resin-treated roving or tape-shaped fiber reinforcement material impregnated with synthetic resin in advance is fed to a die or mandrel.
Manufactures FRP molded products. In this case, the resin treatment of the fiber reinforcing material is carried out by passing the fiber reinforcing material into a liquid in a tank storing a synthetic resin to impregnate it with the resin. Therefore, the bubbles left when impregnating the fiber reinforcement with resin or the bubbles generated when the impregnated fiber reinforcement is laminated tend to remain as they are, which often causes a decline in product quality. Furthermore, the handling of the resin-treated fiber reinforcement material is very poor, resulting in reduced workability.

置を見い出し、本発明に達したものである。 Therefore, as a result of research to eliminate this type of drawback, the present inventors have developed a completely new impregnation device, which differs from the concept of the conventional impregnation tank, that is, a thermosetting resin is injected under constant pressure, and at the same time the resin is heated. The resin impregnating property of the fiber reinforcement is improved by uniformly adhering the plastic resin to the surface of the core material, and then or simultaneously supplying roving or tape, which is a fiber reinforcement, to the resin layer to impregnate the core material surface with the resin. In addition, it is possible to eliminate the generation of bubbles that conventionally occur when laminating fiber reinforcing materials treated with impregnated resin, and it is possible to remove the bubbles that occur when laminating fiber reinforcing materials treated with impregnated resin. The present invention was achieved by discovering a device that can improve the handling of fiber reinforcing materials by guiding them to the surface.

The thermosetting resin composition was continuously introduced into an impregnating device, and first, the thermosetting resin composition that was continuously press-injected from the nozzle of the resin injection part was uniformly adhered to the surface of the core material. In this case, the resin injection part having the above-mentioned nozzle was formed into a tapered shape (tip angle of 120°) so that the resin composition could easily adhere uniformly to the surface of the core material. The thermosetting resin composition to be press-fitted is 100 parts of an unsaturated polyester resin (Polylite FG-283, manufactured by Dainippon Ink & Chemicals Co., Ltd.), which is a thermosetting resin, and 6% naphthene as an accelerator. A resin tank containing 0.15 parts of acid cobalt solution,
From a catalyst tank containing a 55% solution of methyl ethyl ketone peroxide as a curing catalyst and an additive tank containing benzoin ethyl ether as a photopolymerization aid, additive 1.0 and catalyst were added to 100 parts of resin composition components.
A ratio of 1.0 part was continuously sent to a stirrer where it was mixed. The composition was injected through the nozzle of the resin injection part in an amount of 600 g/min at a molding speed of 4 m/min at a pressure of 3 kg/cm 2 .

The glass rovings are impregnated and laminated with a thermosetting resin, and then a nylon forming die with an inner diameter of 45 mm is used to finally form the glass rovings.
After finishing the outer dimensions of the FRP layer, the resin was cured by passing through a curing furnace to obtain a composite pipe. In addition, a high-pressure mercury lamp is used as a curing furnace, and the output

る複合構造材の連続製造方法。1. When continuously manufacturing a composite structural material in which a thermoplastic resin extrusion molded product is used as a core material and the surface thereof is coated with a fiber-reinforced plastic layer, a sealed chamber for coating the fiber-reinforced plastic layer is provided, and the sealed chamber is sealed. A step of drawing the thermoplastic core material into the chamber, a step of drawing the preformed non-resin-impregnated fiber reinforcing material along the shape of the molded product using a guide plate provided at the front part of the sealed chamber, and a step of drawing the thermosetting resin composition into the chamber. A step of injecting the composition under pressure and coating the core material before impregnating the fiber reinforcing material with the composition, and impregnating the fiber reinforcing material with the resin in the sealed chamber, and then preforming directly connected to the sealed chamber. A continuous manufacturing method for a composite structural material, characterized by comprising a step of shaping with a die and a step of curing a thermosetting resin.
