Title:
CARBON FIBER REINFORCED PLASTICS EXTRUDED MATERIAL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/088471
Kind Code:
A1
Abstract:
The present invention makes it possible to manufacture short carbon fiber reinforced extruded material at low cost and use a recycled product. A wire rod according to the present embodiment is a wire rod of CFRTP representing carbon fiber reinforced plastics with long axes of carbon fibers oriented in a long axis direction of the wire rod, wherein 10 to 50 W/W% of short carbon fibers are contained, and an orientation angle thereof is 0 to 7° and preferably 0 to 4° with respect to the long axis direction of the wire rod. The wire rod is extruded from a melting extrusion machine and caused to pass through a cooling water bath, and a wire rod F not completely solidified is wound by a manual wire winding machine with an extending degree thereof adjusted to be obtained. When extruded, melted resin has a Reynolds number Re of 10-6 to 10 and more preferably 10-5 to 1. The wire rod is laid on a pressing machine and formed in sheet material by thermal pressing.
