Method for molding a liquid crystal resin sheet and molding apparatus thereof

A method for preparing a liquid crystal resin composite sheet which comprises the steps of:

• 1) preparing a thermoplastic composite mixture from a thermoplastic matrix resin and a thermoplastic liquid crystal resin which has a liquid crystal transition temperature higher than a minimum moldable temperature of said matrix resin in a mixture proportion wherein the liquid crystal resin is capable of being melt-extruded into a fiber in the matrix resin,
• 2) heating the liquid crystal composite mixture up to a state capable of melt-extruding,
• 3) melt-extruding a liquid crystal film from the melt thermoplastic composite mixture at a shearing rate whereat the liquid crystal resin is capable of melt-extruding into the fibers having an aspect ratio of 3 or more,
• 4) superposing the liquid crystal film to form liquid crystal composite films,
• 5) heating the superposed liquid crystal composite films up to a melt-bonding temperature higher than the minimum moldable temperature of the matrix resin and lower than the liquid crystal transition temperature, and
• 6) pressing the superposed liquid crystal composite films at the melt-bonding temperature while discharging air therebetween to form the liquid crystal resin composite sheet.
