Abstract

PURPOSE:To reduce the occurrence of blow mark inferiority, preventing the occurrence of broken powder and fiber waste from the end surface of a base member by a method in which the peripheral part of a laminate on which metallic foils are placed on its upper and/or lower surface is heated and precured, and then all said laminate is molded under heating and pressurizing. CONSTITUTION:Prepregs A1 are respectively arranged on by one on the upper surface and lower-surface of prepreg B2, while arranging their cross sections. Further copper foils 3 are respectively placed one by one on said upper and lower surface, whereby a laminate is obtained. The range of 10mm from the peripheral part of said laminate toward its central past is gripped by the gripping jig 4 with a heating device and is heated at 120 deg.C for 30min. After only the peripheral part of the laminate has been precured, the peripheral part precured laminate is molded, while being heated and pressurized under 40kg/cm<2> at 170 deg.C for 90min. Thus the objective laminate product may be obtained.

らの繊維のほつれ易さに起因するものであった。Conventionally, multiple sheets of prepreg obtained by impregnating and drying a base material such as paper, cloth, or nonwoven fabric with resin are stacked, and if necessary, metal foil is placed on the top and/or bottom surfaces of the laminate, which is then heated and pressed. When manufacturing a laminate from molding, cutting powder and fiber waste generated from the cut end surface of the prepreg during heating and pressure forming adheres to the top and/or bottom surface of the laminate, and the laminate surface is heated and pressed as it is. This caused dent defects to occur. This dent defect tends to occur particularly frequently when a nonwoven fabric is used as the base material. This inside of the box was caused by the ease with which the fibers frayed from the cut surface of the nonwoven fabric itself.

An adhesive layer is provided as necessary on a metal foil such as am or nickel. It is necessary to pre-cure the peripheral area of the laminate that corresponds to the cut surface of the resin-impregnated long base material cut into the required dimensions, and depending on the combination of the cut surfaces, 2 to 4 sides may be pre-cured. It is used to pre-cure. The pre-curing method may be any method such as a gripping jig with a heating device, a lattice frame with a heating device, etc., and is not particularly limited. Regarding quality and pressure, it is necessary to select appropriate humidity and pressure depending on the type of resin used for the resin-impregnated base material.
