Abstract

Disclosed is a continuous carbon fiber/thermoplastic resin fiber composite yarn and a method for manufacturing the same, wherein the carbon fiber composite yarn provides excellent mechanical properties, is light in weight, moldable, and has excellent impregnating ability. In particular, the composite yarn is provided with these superior properties by including a continuous carbon fiber having excellent mechanical properties, a thermoplastic resin fiber, and the like, and by using a false twist processing machine or a solution bath, and the like in order to manufacture the composite yarn.

First claim

What is claimed is:

1. A continuous carbon fiber/thermoplastic resin fiber composite yarn, comprising:
a carbon fiber; and
a thermoplastic resin fiber,
wherein the carbon fiber is a continuous carbon fiber having a continuous fiber form, and a plurality of the continuous carbon fibers compose a continuous carbon fiber tow having a filament number from 3,000 to 320,000,
wherein the thermoplastic resin fiber is produced from one or more materials selected from the group consisting of polypropylene, polyamide 6, polyamide 66, polyamide 610, and polyester,
wherein the thermoplastic resin fiber has an average thickness from about 0.5 denier to about 5 denier,
wherein the thermoplastic resin fiber has an aspect ratio from about 100 to 10,000, and
wherein the composite yarn has a twist number from about 50 turns/meter (T/M) to about 500 T/M,
wherein the continuous carbon fiber/thermoplastic resin fiber composite yarn is manufactured by interlacing the carbon fiber with the thermoplastic resin fiber by a false twist method.
