Abstract

PURPOSE:To easily obtain FRP without defects even for the complicated shape- FRP by a method in which while covering a laminate with a film and drawing, its inside to e vacuum, the laminate is received in a frame, and then after room temperature-curcing liquid rubber has been injected into this frame and cured, the whole is heated and pressurized by press forming. CONSTITUTION:The laminate 6 laminated on a core member 7 is wrapped in a film 8, and its inside is drawn to be vacuum, and then these are all received in a frame 10. Next, liquid rubber 9 is injected into the frame 10. While keeping the inside of the film 8 in vacuum, the liquid rubber 9 is cured at the room temperature or the temperature at which the resin in the laminate 6 is not cured. In this process, the air between the lapped layers of the laminate 6 is almost removed. Here, the liquid rubber 9 must be treated so that voids or air layers do not enter the frame 10. Further, the rubber elastomer 9 formed by the curing of the liquid rubber is pressurized and heated with the platen 12 of a heating press by way of a pressurizing plate 11, whereby press forming is carried out. The vacuum in the film 8 is preferably kept until the finishing of the laminate 6 curing.

。Next, the Nogu molding method using a typical rubber elastic body will be explained based on the drawings. Figures 2(a), Φ) and 3
The figure shows the configuration of the bag molding method used in the production of EVEM using a rubber elastic body, which is shown in the above-mentioned document ``Utilization of TM in the production of carbon fiber reinforced plastics.'' Figure 2 shows the state shown in Figure 3. It shows the progress along the way. In these figures, 1 is a laminated material in which reinforcing fibers are laminated with resin-impregnated sheets, and 2 is a laminate made by vacuuming the inside.
3 is a rubber elastic body for uniformly pressurizing the recesses, especially the corners; 4 is a cover plate; and 5 is a vacuum seal. In such a bag forming method, a rubber elastic body 3 and a backing plate 4, which are formed in advance to match the shape of the product, hold down the layer material 1 of 8, and these are covered with a Nog film and the inside is evacuated. This applies pressure to the laminated material l. For this reason, pressure can be applied to the corners, which could not be applied sufficiently with the Nogu film alone due to the tension of the film, in the same way as other parts.

いる必要がある。It is possible to use FW material and these together, and furthermore, SMC material and BMC material using short fibers can also be used. As the resin, any commonly used thermosetting resin can be used, but epoxy resins, polyester resins, etc. are preferable. 7 is a core material (molding mold) for the laminated material 6. Here, the core material refers to the material in which the laminated material 6 remains inside even after molding and hardening, and is used as a product. This refers to what is removed. 8 is a film for isolating the laminated material 6 from the liquid rubber 9, which will be described later, as well as evacuating the inside of the laminated material 6, removing voids, etc., and adhering it to the core 7, which is very blue and supple. A film with high elongation is selected. As this film 8, for example, a nylon film, a Teflon film, a zv propylene film, etc. having a thickness of 10 μm or less is used. Reference numeral 9 denotes a liquid rubber (rubber elastic material) that cures at room temperature and is poured into a frame 10 in which a laminated material 6 covered with a film 8 is placed. ~40℃)
It is possible to use rubber that hardens at
Silicone rubber is usually used because it has excellent properties such as thermal expansion coefficient and bulk modulus. 1
Reference numeral 1 denotes a pressure plate disposed on the upper surface of the rubber elastic body 9, and 12 a hot press surface plate for heating and pressurizing the rubber elastic body 9 via the pressure plate 11. Further, 13 is a sealing material for keeping the inside of the film 8 in a vacuum. Note that it is necessary to use a frame lO with high strength so that it can withstand press pressure.

レス加圧を行った後真空を解除してもよい。First, the laminated material 6 laminated on the window side 7 is covered with a film 8, the inside is evacuated, and the whole is placed in a frame mold 10. Next, the liquid rubber 9 is injected into the frame mold 10, and the liquid rubber 9 is cured while the inside of the film 8 is evacuated at room temperature or at a temperature that does not cure the resin in the laminate 6. In this step, most of the air between the laminated layers on the laminated side 6 is removed. Note that here, it is necessary to take care that the liquid rubber 9 does not create voids or air spaces in the frame JO. Then, the rubber elastic body 9 formed by hardening the liquid rubber is pressurized and heated by a heating press surface plate 12 via a pressure plate 11, thereby performing shirales molding. Further, it is desirable to maintain the vacuum in the film 8 until the curing of the laminated material 6 is completed, but if the laminated material 6 does not have a very complicated shape, the vacuum may be released after pressurization.
