Process for making 7xxx series aluminum/fiber reinforced polypropylene hybrid part for automotive crash absorption application

A method to prepare a composite laminate object containing an extrusion grade 7xxx Al substrate and a fiber-reinforced polypropylene layer adhesively laminated to the substrate; is provided. The process includes shaping and cutting an extruded 7xxx aluminum to a profile, assembling a layered arrangement of the 7xxx Al profile as substrate, an adhesive film and a fiber reinforced polypropylene preform, heating the layered arrangement to a temperature of 160-175 C. to melt the polypropylene and activate the adhesive film, applying pressure to at least a surface of the fiber reinforced polypropylene preform to mold the preform to the shape of the extruded 7xxxAl substrate and obtain a semi-finished laminate object, cooling the semi-finished laminate object to 90 C., optionally, cooling the semi-finished laminate object to room temperature for inventory storage; heat treating the semi-finished laminate object at 90 C. for 2 to 8 hours; and then heat treating the semi-finished laminate object at 130 C. to 150 C. for 8 to 16 hours; and cooling the heat treated object to obtain the composite laminate object.

FLEXIBLE SOUND BARRIER AND RIGID MOUNTING ASSEMBLY AND MOUNTING METHOD
20210043183 · 2021-02-11 ·

A flexible sound barrier and rigid mounting assembly, and a method of attaching to a vehicle. The sound barrier assembly includes a rigid substrate, and flexible noise barrier and decoupling layers. The decoupling and noise barrier layers are bonded, and an adhesive bonds the decoupling layer to the substrate. The decoupling and noise barrier layers are fixedly held in place by the substrate. The substrate can include slots that fit over mounting studs on the vehicle wall. The noise barrier and decoupling layers can include mounting holes that extend through both layers, where the mounting holes line up with the slots, and fit over the mounting studs. The assembly can be mounted on the mounting studs and stud fasteners can fit through a mounting hole without compressing the noise barrier and decoupling layers and sandwich the rigid substrate surrounding a slot between the stud fastener and the vehicle wall.

Package For Delivery of Volatile Substance
20210053748 · 2021-02-25 · ·

A package for delivering a fluid volatile substance includes an impermeable shell that defines a reservoir into which a liquid volatile substance, such as oil, may be at least partially filled. A microporous membrane is placed in covering relation to the reservoir to allow emanation through capillarity of the volatile substance. To absorb any liquid that may seep through microporous membrane during use or storage, an oleophilic layer is heat sealed in covering relation to the microporous membrane. Finally, a foil barrier layer is sealed to the shell in covering relation to the microporous membrane. The foil barrier is releasable and once released will activate the volatile substance contained within the reservoir to transition from its liquid phase to a gaseous phase with the vapors carrying the scent of the volatile substance.
