Title:
CARBON FIBER COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/129169
Kind Code:
A1
Abstract:
Provided is a carbon fiber composite material which comprises carbon fibers and a thermoplastic resin, and in which the ratio Y of a carbon fiber bundle (1) with a Mn/(Ln×D) of 8.5×10-1 (mg/mm2) or more with respect to the total weight of the carbon fibers is in the range of 5≤Y<30 (wt%), and the mean value X of Mn/Ln of the carbon fiber bundle (1) is in the range of 3.6×10-2≤X≤3.1×10-1 (mg/mm). Here, Mn is the carbon fiber bundle weight, Ln is the fiber length of the carbon fibers, and D is the fiber diameter of the carbon fibers. According to the present invention, a carbon fiber composite material which has both excellent mechanical properties and impact strength can be provided.
