A non-contact method of joining two components via direct heating of a thermoset adhesive includes applying the thermoset adhesive to at least a first component of the two components. The thermoset adhesive includes a susceptor to reacts in the presence of an electromagnetic field. The method includes placing the first component and a second component of the two components in proximity to an electromagnetic field. In some aspects, the method includes placing the first and second components in proximity to an electromagnetic field of a capacitor. The susceptor interacts with the electromagnetic field to heat the thermoset adhesive via resistive heating. In some aspects, a method of direct-contact heating of the thermoset adhesive includes attaching electrodes to a film comprising the adhesive. The components being joined together are not directly heated by the electromagnetic field, and as a result experience much lower temperatures than the thermoset adhesive.

The system includes a first ejector configured to eject a first material towards a platen to form an object, a second ejector configured to eject a second material towards the platen to form support for portions of the object, at least one portion of the support having a body with at least one fluid path that connects at least one opening in the body to at least one other opening in the body, and a fluid source that connects to the at least one fluid path of the support to enable fluid to flow through the at least one fluid path to remove at least an inner portion of the support from the object.

A conductive polymer composite includes: a thermoplastic polymer; a plurality of carbon nanotubes; and a plurality of metallic particulates in an amount ranging from about 0.5% to about 80% by weight relative to the total weight of the conductive polymer composite.

A graphene reinforced polyethylene terephthalate composition is provided for forming graphene-PET containers. The graphene reinforced polyethylene terephthalate composition includes a continuous matrix comprising polyethylene terephthalate and a dispersed reinforcement phase comprising graphene nanoplatelets. The graphene nanoplatelets range in diameter between 5 m and 10 m with surface areas ranging from about 15 m.sup.2/g to about 150 m.sup.2/g. In some embodiments, the graphene reinforced polyethylene terephthalate comprises a concentration of graphene nanoplatelets being substantially 3% weight fraction of the graphene reinforced polyethylene terephthalate. The graphene reinforced polyethylene terephthalate is configured to be injection molded into a graphene-PET preform suitable for forming a container. The graphene-PET preform is configured to be reheated above its glass transition temperature and blown into a mold so as to shape the graphene-PET preform into the container.

A thermally conductive curing process adds conductive additives to create pathways for dissipating heat during a curing process, thereby reducing the cure time, increasing the output capability, and reducing cost. Conductive particles or short fibers can be dispersed throughout the resin system or composite fiber layers in pre-impregnated or RTM-processed composite material. By disposing conductive particles or short fibers in a resin as part of the curing process, heat generated during the curing process can dissipate more quickly from any type of composite, especially thick composites. Conductive additive examples include multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs), graphene/graphite powder, buckyballs, short fibrous particulate, nano-clays, nano-particles, and other suitable materials.

A polyolefin packaging film is provided. The polyolefin film is formed by a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.

A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets (GNPs) comprising multi-layer graphene are used to reinforce PET, thereby improving the properties of PET for various new applications. Master-batches comprising polyethylene terephthalate with dispersed graphene nanoplatelets are obtained by way of compounding. The master-batches are used to form PET-GNP nanocomposites at weight fractions ranging between 0.5% and 15%. In some embodiments, PET and GNPs are melt compounded by way of twin-screw extrusion. In some embodiments, ultrasound is coupled with a twin-screw extruder so as to assist with melt compounding. In some embodiments, the PET-GNP nanocomposites are prepared by way of high-speed injection molding. The PET-GNP nanocomposites are compared by way of their mechanical, thermal, and rheological properties so as to contrast different compounding processes.
