Title:
MANUFACTURE OF PREFORM FOR COMPOSITE MATERIAL OF VEHICLE
Document Type and Number:
Japanese Patent JP2765653
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily manufacture a preform for a composite material of a vehicle by pouring a suspension obtained by adding an inorganic binder, an organic binder and a coagulant to fibers in a vacuum suction unit, manufacturing a sheet-like material of a wet state, shape-machining it by a cylindrical press before drying to deform the sheet-like material.
SOLUTION: A suspension prepared by adding 1 to 5 pts.wt. of an inorganic binder, 0.2 to 7 pts.wt. of an organic binder and 0.02 to 5 pts.wt. of a dispersant to 100 pts.wt. of fibers is poured in a vacuum suction unit, and a sheet-like material of a wet state is manufactured. Then, in the state that some water is existed, a pressure is applied to a punch 2, sufficiently dehydrated, and then the sheet is removed from a metal mold. The sheet-like preform is wound on a metal mold of a core, its surface is compressed by a rubber press, a volume fraction of the final preform is fixed, and then sufficiently dried.
