Inventor: KURIHARA ATSUSHI
IPC: C08J5/24
Filed: 1988-05-30
Abstract: PURPOSE:To obtain a laminated sheet excellent in humidity resistance and having other characteristics in a well-balanced state, by using a glass fiber contained paper, wherein a glass fiber is contained in paper in a specific ratio, as a paper base material. CONSTITUTION:Glass fiber contained paper is prepared by mixing 3-5wt.% of a glass fiber with raw paper when a paper base material is prepared by a papermaking process. When the mixing ratio of the glass fiber is below 3wt.%, humidity resistance effect is not developed and, when exceeds 5wt.%, no pref. effect is obtained, because the other characteristics of the paper base material are damaged. This glass fiber contained paper is coated and impregnated with a phenol resin and dried to obtain a prepreg. A copper foil is superposed on at least the single surface of a predetermined number of the prepregs and the whole is pressed and integrated under hating to make it possible to obtain a phenol resin copper clad laminated sheet.
