The present disclosure relates to a method for producing a structural component for a motor vehicle, in particular a motor vehicle body component, which has a main body made of a metal material. The main body is provided at least partially with a reinforcing element made of a fiber-composite plastic. The method includes the steps of providing the main body, providing the reinforcing element, joining the main body and the reinforcing element together, and simultaneously heating the main body and the reinforcing element to a temperature and for a period of time which are chosen to be sufficiently high in order to harden both the metal material of the main body and also the fiber-composite plastic of the reinforcing element.

Provided are methods for heat curing of various materials, such as heat curable materials or more specifically potting compounds, which are disposed within cavities with limited access to these materials. Also provided are curing for executing such methods. In some embodiments, a heat curable material disposed within a cavity may be heated by a heating rod protruding into the cavity or through the cavity. The heating rod is thermally coupled to the heat curable material and is used to transfer heat to the heat curable material. For example, the heating rod may include a resistive heating element. The heating element may be positioned in such a way that the heat curable material is selectively heated within the cavity without significant heating of surrounding components. In some embodiments, the heating rod may be also used to compress the part containing the cavity or a stack including this part.

A method for producing a fiber composite laminate, including the steps of applying pressure and/or heat to a first preform, which has one or more dry fiber layers and a thermoplastic elastomer, such that the thermoplastic portion of the thermoplastic elastomer completely impregnates the dry fiber layers of the first preform in at least one first region and only partially impregnates the dry fiber layers in at least one second region and, in a thermosetting polymer matrix, impregnating and curing the fiber layers of the second region of the first preform that are still dry and have not been impregnated with the thermoplastic portion of the thermoplastic elastomer.

An additive manufacturing method includes removing material from a sheet to create a plurality of individual layer segments formed, placing at least two first layer segments adjacent to each other at the same height to form a first layer having a hollow interior, the at least two first layer segments defining a first portion of an exterior of a part, and placing at least one second layer segment above the at least two first layer segments to form a second layer having a hollow interior, the at least one second layer segment defining a second portion of the exterior of the part. The method includes attaching the first layer to the second layer and removing material from the first layer and from the second layer to form the part having a continuous surface that extends along the first layer and the second layer.

In an embodiment, the present disclosure pertains to a method of direct ink writing (DIW). In general, the method includes extruding a resin from a print head, applying radio frequency (RF) heating to the resin, and inducing partial curing of the extruded resin layer-by-layer to thereby form a self-supporting structure. In an additional embodiment, the present disclosure pertains to a system for DIW. In some embodiments, the system includes a print head operable to extrude a resin from a nozzle and an RF applicator.

An electronic device includes a first molded product integrated with an electronic component, and a second molded product secondarily molded outside of the first molded product. The first molded product includes a thermosetting resin, and a first additive contained in the thermosetting resin, and the second molded product includes a thermoplastic resin, and a second additive contained in the thermoplastic resin and having a reactive group that chemically bonds with the first additive. At an interface between the first molded product and the second molded product, the first additive and the second additive are joined to each other by one or more joint actions selected from covalent bonding, ionic bonding, hydrogen bonding, intermolecular forces, dispersion force, and diffusion. As a result, the adhesion between both the molded products can be firmly secured through the molding technique such as the transfer molding method or the compression molding method.

An assembly useful for providing structural reinforcement and/or sound/vibration damping to a hollow member of a motor vehicle is provided which contains an injection-molded carrier made of a heat resistant thermoplastic composition, at least one of the first side and the second side of the carrier has at least one receptacle adapted to receive and retain an insert comprised of a heat-expandable resin composition. The carrier may have a plurality of openings in at least one of the first side or the second side forming a grid or lattice and the assembly may include a mounting member adapted to fasten the carrier to an interior wall of a hollow member.

The invention relates to the production of a composite material of a lobed structure (10) of a flow mixer which comprises a portion having a plurality of lobes (17, 19). For this purpose, a fibrous preform containing a resin will be produced in a simple geometric configuration of developable revolution. This is an intermediate state. By exploiting the thermoformable or thermosetting nature of the resin, the geometry of this intermediate preform is modified to deform it with limited offsets towards the final geometry.

A plated tubular lattice structure is described. The plated tubular lattice structure may comprise a backbone structure which may include a plurality of axial posts and a plurality of pyramidal structures extending laterally from the axial posts and connecting the axial posts at nodes. The plated tubular lattice structure may further comprise a metal plating layer plated on an outer surface of the backbone structure.
