ABSTRACT:
A heating and extruding method for a bulk preform of a fiber reinforced composite material, including a stabbing machine for forming an unpenetrated hole in the bulk preform, a heating machine connected to the stabbing machine for heating the bulk preform by a nitrogen gas, and an extruding machine connected to the heating machine for heating and compressing the bulk preform heated by the heating machine to discharge a predetermined amount of the bulk preform, wherein at least the heating machine to the extruding machine has a sealing structure sealing a nitrogen gas therein. An extruding lip of the extruding machine has a thickness restriction plate and a width restriction plate for respectively adjusting an extrusion thickness and an extrusion width of the melted composite material. Accordingly, oxidation and degradation of resin composing the fiber reinforced composite material can be prevented. Further, a shape of the melted composite material to be extruded can be suited to a desired shape of a molded part to be obtained.
