Title:
INDUCTION GUIDE OF METALLIC WIRE AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2000140939
Kind Code:
A
Abstract:

To make it possible to simultaneously satisfy both of wear resistance and impact resistance and to prevent the flawing of a metallic wire by forming the above induction guide to a cylindrical shape consisting of a carbon fiber woven fabric and thermally cracked carbonaceous material and reinforcing the carbon fiber woven fabric by circumferentially laminating the entire layer in the thickness direction of the cylindrical wall with the carbon fiber woven fabric.

The circumferentially laminated layers of the carbon fiber woven fabric consist of the two-layered structure circumferentially laminated with a carbon fiber filament woven fabric at the outer layer and circumferentially laminated with the carbon staple spun woven fabric at the inner layer. The carbon fiber woven fabric is preferably an acrylic based carbon fiber woven fabric. The induction guide of the metallic wire consisting of the carbon fiber woven fabric and the thermally cracked carbonaceous material is produced by successively circumferentially laminating the carbon fiber staple stable spun woven fabric and the carbon filament woven fabric on the outer periphery of a mandrel, then molding the matrix resin, subjecting the matrix resin to a baking treatment in an inert atmosphere to carbonize the matrix resin and removing the mandrel in a stage of either after the carbonization or before the carbonization.
