Title: Preparation of laminated sheet
Inventor: OTAKE RIICHI
IPC: B32B38/00
Filed: 1989-07-18
Abstract: PURPOSE:To obtain a laminated sheet excellent in surface smoothness, thickness accuracy and dimensional stability by heating an impregnated base material laminate under a substantial ly pressure-free condition to precure the same and subjecting the precured laminate to press molding under pressure to cure the same and subsequently cutting the molded laminate before curing the same under heating in a substantially pressure-free state. CONSTITUTION:A long fibrous base material is impregnated with a solvent non-containing thermosetting resin composition and a predetermined number of the impregnated ones are superposed to obtain an impregnated base material laminate which is, in turn, precured under zero-pressure or low pressure (usually, 3kg/cm<2> or less) not allowing the resin composi tion to flow out excessiviely. For example, the impregnated base materials are superposed and a release sheet or a metal foil is sandwiched therebetween if necessary to form the impregnated base material laminate which is, in turn, preheated while transferred through a heating oven under a substantially pressure-free condition to be precured. Next, the precured laminate is subjected to press molding under heating, for example, by using a continuous double belt press to form a continuous cured body which is then cut and post-cured under zero-pressure or low pressure (usually, 4kg/cm<2> or less) preventing deformation such as warpage. By this method, a laminated sheet free from the wrinkles of the metal foil, having no void inferiority and excellent in surface smoothness, thickness accuracy and dimensional stability is obtained.
