Document Type and Number:
Japanese Patent JP3094320
Kind Code:
B2
Abstract:
Object: The present invention relates to an FRM disc preform for manufacturing an FRM disc used as compressor rotors of aircraft engines. In the prior art, a preform manufactured by a spirally formed reinforcing fiber collapses easily, because a spirally laminated reinforcing fiber are not fixed between an upper layer and a lower layer and there is a considerable difficulty in handling thereof in the post-processes such as a laminating process. Construction: An FRM disc preform (1) according to the present invention comprises a reinforcing fiber (2) wound in a spiral shape with flat faces and a spray coating (7) of a matrix metal formed on said flat face of the spirally wound reinforcing fiber (2) to hold the shape by fixing the upper layer and the lower layer of the spiral. Thereby, the spiral shape is held tightly without collapsing and handling in a laminating process and a combined forming process becomes extremely simplified, thus the manufacturing efficiency and accuracy of an FRM disc can be enhanced.
