Disclosed is a film-removal/sorting method for coated resin products, which comprises a film removal step (S) of feeding a target material comprising a mixture of plural types of coated resin products each having a different softening temperature in at least either one of a film () and a substrate () thereof, into a film removing apparatus (), and heating the target material in the film removing apparatus () up to a temperature allowing the substrate () or the film () of at least either one of the coated resin products to be softened in a non-molten state, so as to remove the film () from the substrate (), and a sorting step (S) of sorting the target material after being subjected to the film removal step (S), between a film-free material (A) consisting of the substrate () of the coated resin product which has succeeded in removing the film () therefrom, and an untreated target material (B) consisting of the remaining coated resin products having residual films (). The film removal step (S) and the sorting step (S) are repeatedly carried out while increasing the temperature of the target material in the film removal step (S) stepwise within a temperature range equal to or less than a highest one of softening temperatures of the films () and the substrates () of the coated resin products.

A method for recycling comprises a pulverization step (S) of pulverizing thermoplastic resin molded articles, each having a different softening point in a resin substrate and having a metal part and a coupling film, a metal-material selection-removal step (S) of selecting and removing a metal material from pulverized pieces, a pulverized resin-material selection step (S) of selecting a target pulverized resin material for recycling by allowing the pulverized pieces from which the pulverized metal material has been removed to drop and by ejecting gas towards either one of the target pulverized resin material and a non-target pulverized resin material for changing a drop direction thereof, and a coating-film peeling step (S) of peeling the coating film from the resin substrate by applying a shearing force to the target pulverized resin material under the softening point of the resin substrate of the target pulverized resin material for recycling.

The present invention relates to a method for preparing a composite material comprising a matrix resin of a thermal plastic resin and a liquid crystal resin which has a liquid crystal transition temperature higher than the minimum temperature of capable of molding said thermal plastic resin and which is formed into a fiber structure as a reinforcing material. The method is characterized in that the composite composition is subjected to a melt extrusion process at an apparent shear rate of 3.times.10.sup.2 to 10.sup.5 sec.sup.-1 and above the liquid crystal transition temperature. The resulting material in a filament or thin film has fibers of the liquid crystal resin having an aspect of more than 3 in the matrix resin, so that it is provided with an improved tensile strength by further being subjected to a drawing process at a drawing ratio of 11 to 120. As the composite materials have too small diameter or thickness to be molded in a desired product, they are preferably further subjected to a gathering process, a folding process or a laminating process in which a plurality of strand or film materials are welded to each other at the surface thereof and formed into a strand or sheet form capable of molding.

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.

When a resin article having at least one thickened part is blow-molded, a parison is extruded and suspended between halves of a blow mold the inner surface of which defines the outer shape of the article to be molded. An expander panel is inserted into the space inside the parison, and is moved toward the part of the inner surface of the blow mold corresponding to the thickened part of the article to press thereagainst a part of the parison. Then the blow mold is closed and pressurized gas is blown into the parison.
