FIBER REINFORCED RESIN MOLDED BODY AND METHOD FOR PRODUCING THE SAME
A resin-integrated fiber sheet 1 for vacuum forming for producing a fiber reinforced resin molded body through vacuum forming includes: unidirectional continuous fibers 2 that are spread fibers of a continuous fiber group and arrayed in parallel in one direction; bridging fibers 3 lying in directions crossing the unidirectional continuous fibers 2; and thermoplastic resin 4 present on part of the surface of the unidirectional continuous fibers 2 to unify the unidirectional continuous fibers 2 and the bridging fibers 3. A fiber reinforced resin molded body of the present invention is a vacuum formed body in which two or more of the resin-integrated fiber sheets 1 are stacked. A method for producing the molded body of the present invention includes subjecting the resin-integrated fiber sheets 1 to vacuum forming from a lower mold with a vacuum line and pressurizing the sheets with compressed air from an upper mold. Thus, the present invention provides a resin-integrated fiber sheet for vacuum forming having excellent shapeability and avoiding voids, a molded body including the same, and a method for producing the molded body including the same.
Laminate body and packaging bag using the same
A laminated body having at least two or more different layers, wherein the laminate body is characterized by satisfying the following requirements (1) to (5): (1) the laminate body has a heat-sealing layer as at least one of the outermost layers, wherein the heat-sealing layer includes a polyester based component containing ethylene terephthalate as a main constituent component, and a sealing strength of 8 N/15 mm to 30 N/15 mm; (2) at least one layer other than the heat-sealing layer is an inorganic thin film layer; (3) a water vapor permeation rate of 0.1 g/m.sup.2.Math.d to 6 g/m.sup.2.Math.d; (4) an oxygen permeation rate of 5 ml/m.sup.2.Math.d.Math.MPa to 30 ml/m.sup.2.Math.d.Math.MPa; and (5) a heat shrinkage rate of −5% to 5%.
LAMINATE AND HOT MELT-TYPE ADHESIVE LABEL
Provided is a laminate and a hot melt-type adhesive label that suppress curling due to swelling while having a pulp-paper feel. The laminate includes a porous substrate layer and an adhesive resin receiving layer on one side of the porous substrate layer, and the adhesive resin receiving layer contains an amorphous resin.
MULTILAYER PULTRUDED STRUCTURE HAVING A CHEMICAL RESISTANT AND WEATHERABLE TOP LAYER
The invention relates to a multilayered pultruded structures having a weatherable cap layer over a pultruded substrate. The cap layer provides improved weatherability, chemical resistance and surface quality for pultruded structures. The cap layer is either an acrylic, vinyl or styrenic cap layer covered with a thin layer blend of polyvinylidene fluoride and acrylic polymers, or a cross-linked acrylic outer layer. A useful cap layer would be a UV resistant acrylic cap layer, such as a Solarkote® resins from Arkema, covered by a co-extruded blend of polyvinylidene fluoride, such as Kynar® resins from Arkema, with an acrylic resin, such as Plexiglas® resins from Arkema. The highly weatherable and chemical resistant pultruded structure is especially useful in window and door profiles.
