In certain embodiments, land vehicles are provided as delivery vehicles and/or utility vehicles. A land vehicle includes a frame structure having a front cage that defines an operator cabin and a rear floor positioned rearward of the front cage. The frame structure supports a plurality of wheels to permit movement of the vehicle relative to an underlying surface in use of the land vehicle. An underside of the frame structure is disposed in confronting relation with the underlying surface.

Land vehicles, modular systems for forming monocoques of land vehicles, and methods of forming monocoques of land vehicles using modular systems are envisioned. In certain embodiments, the land vehicles are provided as delivery vehicles and/or utility vehicles. A land vehicle includes a monocoque supporting a plurality of wheels to permit movement of the vehicle relative to an underlying surface in use of the land vehicle.

In certain embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, a utility cabinet, and a flatbed. In other embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, and a flatbed. In some embodiments, the front cage at least partially defines an operator cabin, the rear floor is positioned rearward of the front cage in a longitudinal direction, and the intermediate section is disposed at least partially between the front cage and the rear floor in the longitudinal direction.

A method for trim preparation of car interior parts includes the steps of cutting out templates of natural jute or linen fabric primer and a second natural cotton fabric or fiber paper, and impregnation of the fabrics with a water-based adhesive resin in each of the fabrics and drying thereof. The method also includes the steps of fabric pressing, forming a structure by adding an adhesive layer and a decorative sheet, applying primer on the decorative layer and drying it, and applying at least one layer of varnish onto the primer layer and drying it.

A method for forming a fibre article, the method comprising: locating a fibre preform between a first diaphragm and a second diaphragm, the preform comprising a heat-activatable binder; drawing a vacuum between the first and second diaphragms so as to hold the preform captive between the diaphragms; positioning a first heater plate in contact with the first diaphragm; positioning a second heater plate in contact with the second diaphragm; drawing a vacuum between the first diaphragm and the first heater plate so as to increase the contact between the first diaphragm and the first heater plate; releasing the vacuum between the first diaphragm and the first heater plate; and drawing a vacuum between the second diaphragm and the second heater plate so as to increase the contact between the second diaphragm and the second heater plate.

A method is provided to fasten a pin in a target position extending at least partially into a cavity with a distance (D) between a bottom surface of the cavity and a facing end of the pin. The pin is positioned at the target position, and the distance (D) is determined between the bottom surface of the cavity and the facing end of the pin in the target position. The pin is removed from the cavity, and a rigid spacer is applied on the bottom surface. A thickness of the rigid spacer equals the distance (D) between the bottom surface and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the rigid spacer, and the pin is repositioned at the target position. The adhesive is then cured to obtain a joint between the pin and the second component.

A method is provided for joining a pin member of a first component to a second component with a cavity, using an adhesive, to fasten the pin in a target position extending at least partially into the cavity. A distance (D) is provided between the bottom surface of the cavity and the facing end of the pin. A flexible spacer is positioned on the bottom surface of the cavity. The thickness of the spacer equals or exceeds the distance (D) between the bottom surface of the cavity and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the flexible spacer, and the pin is positioned in the target position. The adhesive is cured to obtain a joint between the pin and the second component.

A method is specified for producing a structural component, in particular for an aircraft, ground vehicle, or watercraft, or for a rotor blade of a wind turbine, in which method an arrangement of fibers and plastic material is laid in a mold and subjected to an increased pressure and an increased temperature, wherein a mold is used which comprises at least one recess in which a reinforcing element is arranged. The object is to be able to cost-effectively produce a structural component of this type. For this purpose, it is provided that the reinforcing element is laid in the recess together with a core, wherein a differential volume between the recess and core, at least in a predetermined region, is chosen such that it is smaller than a segment of the reinforcing element arranged in said region by a predetermined amount.

Land vehicles, modular systems for forming monocoques of land vehicles, and methods of forming monocoques of land vehicles using modular systems are disclosed herein. In certain embodiments, the land vehicles are provided as delivery vehicles and/or utility vehicles. A land vehicle includes a monocoque supporting a plurality of wheels to permit movement of the vehicle relative to an underlying surface in use of the land vehicle.

The invention relates to injection molded parts, preferably injection molded parts in the form of automotive interior parts, having a low TVOC content and a low tetrahydrofuran content based on polybutylene terephthalate synthesized from butanediol and terephthalic acid, compounded in a compounder under vacuum and subsequently processed by injection molding, wherein TVOC stands for “Total Volatile Organic Compounds”.
