Manufacture And Use Of Nonwoven Products Utilizing Ribbon Cross-Section Fibers For Automotive Applications
A molded automotive textile nonwoven and its associated method of manufacturing includes flat staple fibers exhibiting a width to thickness ratio of 2 to 10 and a denier in the range of 2 to 30. The molded automotive textile non-woven is a three-dimensional (3D) structure that includes one or a plurality of protrusions or recesses which fits to the metallic vehicle floor pan of the vehicle.
BLOW-MOLDING METHOD
Provided is a blow-molding method capable of suppressing generation of blister-like bubbles and producing a high quality hollow molded article when forming a thick hollow molded article by blow-molding. A blow-molding method includes setting a die-slit interval in a die head according to a target wall thickness of a hollow molded article to be molded, extruding a molten resin in an accumulator into a cylindrical shape from the die slit to form a parison, and molding the parison in a mold. The die-slit interval is made smaller than a value set according to the target wall thickness at start of extrusion, and then is increased to match the value set according to the target wall thickness. The value set according to the target wall thickness is preferably corrected considering wall thickness reduction due to drawdown. The wall thickness of the hollow molded article is preferably 3.5 mm or more.
VEHICLE EXTERIOR COMPONENTS HAVING DISCONTINUOUS PLATED FEATURES
A component for a vehicle comprises two or more first members each formed of a plateable resin and defining a front surface, wherein the front surfaces of the first members (i) are spaced apart from each other such that they appear discontinuous and (ii) collectively correspond to an outer surface of the component, a second member formed of a non-plateable resin and connected to each of the first members and a chrome plating applied to one or more exposed surfaces of each of the first members. A method of manufacturing the component involves utilizing one or more molds and removing a non-plated component comprising the first members and the second member from one of the one or more molds, attaching the non-plated component to a plating rack, such as via a permanent or temporary conductive circuit, and then performing the chrome plating.
Fiber preform of commingled fiber bundle for overmolding
A fiber preform for use in a resin transfer molding or liquid composite molding process and process of making the same are provided. The preform includes a substrate, a fiber bundle arranged on the substrate in a predetermined pattern and attached to the substrate by a plurality of stitches of a thread. The fiber preform is capable of being pre-formed into a three-dimensional shape. The fiber preform along with a sheet of preformed thermoset resin that impregnates at least a portion of the fiber preform forms a composite material. The fiber preform reinforces areas of stress concentration of a core to form a vehicle component.
Programable deformation of elastomeric parts using internal lattice structures
A compressible part having a solid portion and a compressible portion. The solid portion includes a first polymer material. The compressible portion has a lattice structure adjacent to the solid portion. The compressible portion includes a second polymer material that is an elastomeric polymer. The lattice structure is configured to provide for increased elastic deformation of the compressible part under compressive stress compared to the same compressible part made completely of the elastomeric polymer in solid form.
POLYESTER COMPOSITION AND ARTICLE PREPARED THEREFROM
A composition includes 100 parts by weight of poly(alkylene terephthalate) and 0.01 to 2 part by weight of a compound represented by Formula (1), a partially saponified derivative thereof, or a combination thereof, (1) wherein R.sup.1, R.sup.2, and n are defined herein. The composition, which excludes copolymers of an unsubstituted or substituted styrene and an unsaturated nitrile, is useful for molding articles with very smooth surfaces. For example, the composition can be used to mold directly-metallizable substrates for automotive headlight reflectors and bezels.
