Vehicle seatback cover and manufacturing method thereof
The present disclosure relates to a manufacturing method of a vehicle seatback cover, comprising a lightweight composite manufacturing step of manufacturing a lightweight composite using a reinforcing fiber and a thermoplastic resin fiber, a lightweight composite forming step of forming the lightweight composite into a vehicle seatback cover shape and preparing a vehicle seatback cover material, and a carpet bonding step of bonding the vehicle seatback cover material and a carpet material.
METHOD OF MANUFACTURING A LIGHTWEIGHT, STRUCTURALLY REINFORCED OBJECT OF THERMOPLASTIC MATERIAL
Lightweight, structurally reinforced thermoplastic objects comprising at least one reinforcement zone are manufactured by providing a heatable rigid forming chamber with a chamber volume. At a temperature below the thermoplastic softening temperature, the chamber is loaded with a plurality of thermoplastic lofting bodies and a plurality of thermoplastic reinforcement bodies wherein the lofting bodies are heat-loftable bodies comprising a thermoplastic matrix containing an elastically compressed assembly of reinforcement fibers embedded therein, lofty non-woven bodies comprising an elastically compressible assembly of reinforcement fibers and thermoplastic fibers. Upon closing the chamber, lofting bodies of lofty non-wovens are elastically compressed, producing an internal pressure. After heating the chamber above softening temperature, reinforcement bodies and lofting bodies are ow thermoplastically formable, and lofting bodies configured as heat-loftable bodies produce a second internal pressure. After a predetermined processing time, the chamber is cooled yielding a structurally reinforced object.
LAYERED COMPOSITE COMPRISING POLYCARBONATE AND A POLYCARBONATE BLEND FOR IMPROVED PAINTABILITY
The present invention relates to a layered composite comprising a poly carbonate-based matrix, possibly containing fibres, and an outer layer of special poly carbonate-polyester blends, and also to a layered composite such as that described above and provided with painting on that side of its outer layer which is facing away from the matrix, to a method for producing these composites and also to their use for the production for example of automobile add-on parts.
CURABLE COMPOSITIONS
The present invention is directed to a curable composition including: an isocyanate-functional prepolymer; an epoxy-containing component present in an amount of at least 10 percent by weight of the composition; and a latent curing agent having an ability to react with at least one of the isocyanate-functional prepolymer and the epoxy-containing component upon exposure to an external energy source. The present invention is also directed to methods of making the compositions, methods of coating a substrate, methods of adhering substrates and coated substrates.
FIBER-REINFORCED RESIN SHEET, STACKED BODY OF SAME, AND METHOD FOR PRODUCING FIBER-REINFORCED RESIN MOLDED ARTICLE
A fiber-reinforced resin molded article is produced by pressing a plurality of thermoplastic base material sheets, each of which contains a plurality of reinforcing fibers, in a stacked state where the base material sheets are stacked so that the fiber directions (orientation direction of the reinforcing fibers) are alternated. Each base material sheet is provided with a cut including: a plurality of lengthwise cut lines extending parallel to the fiber direction; and a plurality of crosswise cut lines extending parallel to a direction that is perpendicular to the fiber direction. A plurality of cut interruption parts for interrupting the lengthwise cut lines in the fiber direction are formed. The cut interruption parts are arranged in a staggered manner so as to be displaced from each other in the fiber direction.
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.
