Title: Manufacture of brake frictional member
Inventor: YOSHII AKIHIRO
IPC: F16D69/00
Filed: 1992-08-10
Abstract: PURPOSE:To provide a manufacturing method of brake frictional member which can prevent crack or blistering from occurring positively after heating and compression molding and after-cure. CONSTITUTION:By forming a gas venting process where a molded element is pressurized and released repeatedly within a heating and compression molding process, and setting the gas venting process period to 2 minutes or more, gas generated inside the molded element can be discharged to the outside effectively. Moreover, by setting the gas venting process period to half or more of the total time of the heating and compression molding process, gas generated during a pressurizing and holding process after the gas venting process can be prevented from staying in the molded element too much. It is thus possible to prevent crack or blistering from occurring in the molded element before or after after-cure because of the influence by gas.
