초록 ▼

A continuous FRTP prepreg manufacturing apparatus comprises an extruder, a crosshead having a main body internally provided with a resin chamber for containing a molten thermoplastic resin extruded therein by the extruder and joined to the discharge end of the extruder, a cooling unit disposed outside and near the exit of the main body of the crosshead, and a winding unit for taking up a prepreg. A fiber bundle inlet unit and a fiber bundle outlet nozzle unit are provided respectively at one end and at the other end of the main body of the crosshead. Guide rollers and impregnating rollers are arranged within the main body of the crosshead so that a tension is applied to the fiber bundle during impregnation or so that the fiber bundle is expanded during impregnation and is condensed after impregnation. The resin-impregnated fiber bundle is heated to a temperature higher than the melting point of the thermoplastic resin at the fiber bundle outlet nozzle unit, and then the resin-impregnated fiber bundle is cooled to a temperature below the melting point of the thermoplastic resin immediately after being delivered from the fiber bundle outlet nozzle unit to form a continuous FRTP prepreg.

대표청구항 ▼

A method of manufacturing a continuous fiber reinforced thermoplastic prepreg comprising the steps of, (a) introducing a fiber bundle into a molten thermoplastic resin chamber having an inlet and an outlet; (b) passing the fiber bundle through the molten thermoplastic resin under tension over a rotary impregnating means frictionally rotated by said fiber bundle, said rotary impregnating means being located within said thermoplastic resin to frictionally impregnate said fiber bundle; (c) heating the fiber bundle impregnated with the molten thermoplastic resin at the outlet of said resin chamber containing the molten thermoplastic resin in order to prevent voids; and (d) cooling the fiber bundle impregnated with the molten thermoplastic resin outside the resin chamber containing the molten thermoplastic resin to a temperature below the melting point of the thermoplastic resin, wherein the fiber bundle is expanded before being introduced into the molten thermoplastic resin, and the expanded fiber bundle is condensed before being delivered from the resin chamber containing the molten thermoplastic resin.
