Abstract

PURPOSE:To prevent prepregs from being displaced so as to exclude defectives and to improve the production efficiency, by arranging tapes to peripheral ends of a laminated body when a laminated board is formed under heat and pressure that has been prepared by impregnating substrates with a resin, drying the thus prepared prepregs and laminating the prepregs. CONSTITUTION:Prepregs 1 are prepared by impregnating substrates to be laminated such as paper, (non)woven fabric or the like of glass fiber, polyester fiber, etc. with a resin liquid for example a phenolic resin liquid and drying the impregnated substrates. A prescribed number of such prepregs 1 are laminated as shown at (a). The tapes 4 such as paper tapes, cloth tapes, plastic tapes, metal foil tapes, etc. are stuck to peripheral ends 2 such as the side surfaces or peripheies of the laminated body (a), and then forming under heat and pressure is carried out to obtain the intended laminated board. USE:The laminated board can be used for electric or electronic components, parts of computers, etc.

ある。Conventional fiIi laminates were made by impregnating the laminate base material with laminate resin and then layering the required number of dried prepregs, which was then sandwiched between molding plates and molded under heat and pressure. When the filt layer incorporated in the process is transported to the shoe press machine or inserted between the hot plates of the molding press machine and placed in a fixed position, the preg (1) may shift. The amount of effort and time lost during correction was large, and the misalignment that occurred when the hot plate came into contact with the pressurized plate was unavoidable, resulting in frequent occurrence of defects.

る。The present invention solves the above-mentioned drawbacks, since the tape is placed on the peripheral edge of the shoe body and then heated and press-molded.
It is possible to prevent the Gripreg from shifting when transporting the laminate, inserting it into a molding press, applying pressure, etc., thereby preventing the occurrence of defects and improving production efficiency.

よく望ましいことである。An embodiment of the method of the present invention will be described below with reference to the illustrated embodiment. The examples shown in Figure 1 include phenolic resin, cresol resin, epoxy resin, unsaturated polyester resin, melamine resin, polyimide, polybutadiene, polyamide, polyamideimide, polysulfone, polybutylene terephthalate, polyether ether ketone, fluorinated resin, etc. The resin solution for laminates, which can be used alone, as a modified product, or as a mixture, can be made from inorganic fibers such as galanu and asbenute, organic synthetic fibers such as poly/Nisdel, polyamide, polyvinyl alcohol(2)-alcohol, acrylic, and natural fibers such as cotton. Paper tape, cloth tape,
A tape 8 such as a glass tape or a metal foil tape is applied and molded under heat and pressure to obtain a laminate. In addition, by placing metal foil such as copper foil, aluminum foil, nickel foil, or brass foil on the upper surface, upper, or lower surface of the Bripreg crushing body a, single-sided metal-clad laminates or double-sided metal-clad laminates can be produced. It is something that can be obtained. Furthermore, if the shoe body 3 is relatively thick, the tape 11 may be applied only to the side surface of the fan body, but if it is thin, it is more desirable to apply it to both the periphery and the side surface to prevent slippage.
