发明名称 PREPARATION OF ELECTRIC LAMINATED SHEET
摘要 <p>PURPOSE:To prevent the generation of the interfacial release and interlaminar crack between a filler and resin by performing the filling a through-hole with a filler compounded resin powder by rubbing-in. CONSTITUTION:A filler compounded resin powder 4 is received in the through- holes 1 of a metal plate 2 in a slightly large amount so as to rise. This filler compounded resin powder 4 may be scattered on the entire upper surface of the metal plate 2. As the filler compounded resin powder 4, one prepared by powdering the same filler compounded resin as that infiltrated in a prepreg 3a is used. As a filler, a needle-like powder obtained by finely cutting and grinding down a glass fiber or an aramide fiber can be designated. The filler compounded resin powder 4 received in the through-holes 1 of the metal plate 2 having the prepreg 3a temporarily bonded thereto is rubbed in while pressed by a rubbing-in member 10. By this method, the through-holes 1 are filled with the filler compounded resin powder 4 in a relatively easy manner. A filling ratio is enhanced by rubbing-in and the inflow of the resin from the prepreg at the time of molding is reduced and the deviation of the filler in the through- holes is eliminated.</p>
