ABSTRACT:
The present invention is to provide a method and an apparatus for molding a resin composite sheet having an improved composite property. Therefore, the method and apparatus according to the present invention comprises a step or means of extruding film sheets through plurality of dies from a thermoplastic composite composition comprising a thermoplastic matrix resin, a liquid crystal resin which has a liquid crystal transition temperature higher than a minimum temperature of the matrix resin and an ability to be melt-extruded into a fiber in the matrix resin; a step or means of laminating the liquid crystal resin composite films into an integral or one body sheet by superposing and pressing them to each other at a melt-bonding temperature higher than the minimum moldable temperature of the matrix resin and lower than the liquid crystal transition temperature while discharging the air therebetween by means of the pressing pressure.
