MANUFACTURE OF FIBER COMPOSITE BODY

摘要

PURPOSE:To provide a method wherein a bundle of a number of reinforcing fibers is passed on a projected curved face of a vibrator with a specified length and a powder resin is fed on the vibrating fiber bundle and the resin is bonded, caught and melted on each monofilament. CONSTITUTION:A bundle F1 of reinforcing fibers consisting of a number of continuous filaments is unwound from an unwinding roll 3 not to cause twists by means of a winding roll 11 and it is passed through while it is brought into contact with a projected curved face 1 of a vibrator 2 through a guide bar 6 to open the bundle F1 of the fibers. A powder thermoplastic resin A is fed to the opened fiber bundle F1 and the resin is adhered on each filament and is caught among the filaments each other. The resin-adhered reinforcing fiber bundle F2 is arranged into a sheet-like shape by means of guide bars 5 and 7 and it is integrated into a sheet-like shape by heating and melting the resin between heating rolls 10. The obtd. sheet-like fiber composite body S1 is wound on a winding machine 12 by means of a winding roll 11. Therefore, the resin is sufficiently penetrated among filaments each other and the distribution of the amt. of the resin accordingly becomes uniform.
