To develop low cost and high strength CFRTP, in-situ Automated Fiber Placement in a direct process (AFP-D) has been proposed. Thermoplastic tape and carbon fiber spread tow are independently supplied to the AFP-D system. The carbon fibers heated by a diode laser are impregnated with the resin via a compaction roller and directly laminated on already laminated fibers. This paper shows fundamental analyses of the AFP-D manufacturing process and its demonstration.
