摘要：A continuous FRTP prepreg manufacturing apparatus comprises an extruder (1),a crosshead (5) having a main body (11) internally provided with a resin chamber (9) forcontaining a molten thermoplastic resin (13) extruded therein by the extruder (1) andjoined to the discharge end of the extruder (1), a cooling unit (18) disposed outside andnear the exit of the main body of the crosshead, and a winding unit (19) for taking up aprepreg. A fiber bundle inlet unit (8) and a fiber bundle outlet nozzle unit (10) areprovided respectively at one end and at the other end of the main body (11) of thecrosshead (5). Guide rollers (14) and impregnating rollers (15) are arranged within themain body (11) of the crosshead (5) so that a tension is applied to the fiber bundle (6)during impregnation or so that the fiber bundle (6) is expanded during impregnation andis condensed after impregnation. The resin-impregnated fiber bundle (6) is heated to atemperature higher than the melting point of the thermoplastic resin (13) at the fiberbundle outlet nozzle unit (10).
