Continuous carbon fiber reinforced thermoplastic plastic composite having excellent impregnation properties and a method for manufacturing the same

A method for manufacturing a continuous carbon fiber reinforced thermoplastic plastic composite comprising:

• preparing a continuous carbon fiber in which carbon filaments are sized by a sizing agent comprising a water soluble resin;
• removing the sizing agent by using a solvent having a difference in a solubility parameter from that of the water soluble resin as 2.0 or less based on SI units (MPa1/2);
• and
• impregnating a bundle of the carbon fiber that is removed of the sizing agent in a thermoplastic plastic,
• wherein
• the continuous carbon fiber reinforced thermoplastic plastic composite comprises a continuous carbon fiber impregnated in thermoplastic resin,
• the continuous carbon fiber has a width of 4 times to 8 times as wide as a width of the continuous carbon fiber before the continuous carbon fiber is impregnated in the thermoplastic resin,
• the continuous carbon fiber reinforced thermoplastic plastic composite has a flexural strength of 460 Mpa or more, and
• the continuous carbon fiber reinforced thermoplastic plastic composite has a flexural stiffness of 38 Gpa or more.
