Evaluation report on the study on the application of 3D woven C/C composite materials; Sanjigenori C/C composite zairyo no kikai buhin eno oyo ni kansuru kenkyu hyoka hokokusho

Abstract

The paper described a study made during 1995 through 1998 on the application of 3D woven C/C composite materials to machine parts. The materials are large in rigidity, small in specific gravity, excellent in specific rigidity, and suitable for high speed rotation. They are excellent in heat resistance/dynamic reformation and expected as materials which can exceed limits of the existing steel for machine parts. However, to use them as machine parts, a possibility of high precision cutting is required. Therefore, a study was made on metal multi-layer membrane coating to C/C composites. Pitch-system high-elastic carbon fibers were made a 4-directional material by orienting horizontally in 3 directions at 120 degrees per plane and also orienting vertically. Various materials such as W, Mo and WC were coated by the laser assisted plasma hybrid spraying method. High adhesion coats with little pore were obtained. Multi-directionally woven C/C composites used to be poor in surface precision workability, but the problem was able to be solved by coating surfaces with metal layers and metal multi-layer membranes. The application is expanded not only to polygonal mirrors (for laser printing machine) and milling spindles, but largely to machine parts. 11 figs., 1 tab.
