ができる。Then, the sheet r/'i is trimmed to match the size of the molded body to be molded, and then macerated in a reheating furnace.
It was heated to a temperature above the melting point of IJ Lux fat to soften it, and then pressed in a matte metal diamond maintained at a temperature below the melting point of Matrix Shigenobu, and solidified to obtain the desired curved shape. It can be formed into a molded body.

として注目さnている。This method is characterized by the fact that the Osugi press molding of plastic resin is successful in 6I, and its molding cycle is short. The molded product thus obtained exhibits excellent round physical properties due to the reinforcing effect of the long fiber reinforcement, and is attracting attention as an alternative to steel.

る二次加工工程に際し、看しい障害となる。However, some people say that the disadvantages of this rod molded body are that the reinforcing material is delicate.
In flat strength reinforced fibers such as glass fibers,
These fibers stand out on the surface of the molded product, impairing the flatness of the surface and causing surface defects in the molded product. Moreover, this causes a problem in the appearance rate of the molded product and also in subsequent secondary processing steps such as painting, plating, printing, etc. after molding.

いる。The reason for this defect is first explained in the production of the transverse 8-reinforced thermoplastic resin sheet which is the forward bending body of the press-formed product.The filament-like t'ft is the result of a reinforcing fiber mat made up of strand-like reinforcing fibers. 9) Supply a molten thermoplastic resin layer 'f' on the upper and lower sides, and replace the air inside the mat layer with the molten resin. In order to complete the process, the laminate is pressurized from the top and bottom, and the laminate is cooled under pressure to obtain a flat sheet.

出たし友。The present invention has investigated various techniques for preventing the protrusion of reinforcing fibers from the surface of molded products in the related art, and as a result, it has been found that at least the outer surface of the fiber-reinforced thermoplastic resin is more melting point of different resins
The 1ll'fe facility was opened as a $1 body for nine 't-forming processes, and a molded product of reinforcing material fibers was produced by heating one body of this structure in a certain m range and then carrying out press molding. A friend who discovered that it is possible to completely eliminate the phenomenon of surface exposure.

必要である。In addition, in order to assemble such a laminate for molding, it is necessary to use a molten resin containing a fiber layer that will become the core without melting the surface resin. - It is necessary to form a strong bond in which the two are integrated by bonding and applying pressure.

来ないことが’FIJ月した。In the production of the conventional fiber-reinforced thermoplastic resin sheet described above, a high-melting point resin sheet (or film) that does not melt is simply laminated on the surface and then press-molded with T-condensation, which achieves the purpose. It's been a month since I've had any luck at all.

The upper layer of Romikake is also made of A-type resin, and due to the difference in affinity between them, the bonding force does not change at all.Ninthly, this one piece of wood was used for pressure press molding. The surface layer of the molded product easily separates from the surface layer when the molded product is in contact with the material.

こと:てなる。In addition, the Vi concentration during the pressure layering of the bath melt resin is 1 of the raw material resin.
The viscosity is determined by the molecular force, the magnetic layer during extrusion, and the surface temperature of both rolls 4.5, but if the viscosity is too low or the pressing force is too strong, the porosity of the melting finger may be reduced. (Resin J11#*tmv)
The porous sheet 1 is exposed up to c, or the resin penetrates to the back surface of the porous sheet and the porous sheet 5Ufi becomes **
